Unless of course you were a 'person of substance', in which case you would recognize the puzzle immediately and infer the solution as option A at about the point in the conversation where the editor paused for time to guess an answer. If you have never seen this puzzle before and knew the answer was A instantly, your IQ and/or education level is probably pretty high. And if you have to work it out, you're likely not of any meaningful substance. That was the gist of it. Quite of a few of these lowKey classist digs and conversational gotchas end up circulating among communities of people who want to feel high IQ without going through the 'proving it to other people' part.

There's a simpler way of solving this: Step 1: Assume Cedar is the cleric. Then his statement is equivalent to 'I am lying', which is self-contradictory. Thus, Cedar is not the cleric. Step 2: Assume Agan is lying. Then Beorn must be both a liar and the cleric. But then, 'Agan drank a lying potion' is true and 'I am not a cleric' is false, making Beorn's either-or statement correct, which contradicts him being a liar. Thus Agan must be telling the truth. Step 3: Assume Beorn is lying. Then, per Agan's statement, which from step 1 we know to be true, he cannot also be the cleric. But then, 'Agan drank a lying potion' is false and 'I am not a cleric' is true, making Beorn's either-or statement correct, which contradicts him being a liar. Thus Beorn must be telling the truth. Step 4: We know from step 3 that Beorn is telling the truth, and we know from step 2 that Agan didn't drink the lying potion, so the 'I am not a cleric' part of the either-or statement must be the true part. Thus, one of the other two must be the cleric. And per step 1, we know it isn't Cedar, so that leaves Agan as the Cleric by process of elimination. The truthfulness of Cedar's statement is irrelevant to the solution, so ignoring it leads to simpler logic. Just thinking about the problem for a bit makes this obvious: none of the other statements refer to Cedar at all, so we can't determine its truthfulness from them. And in order to determine its truthfulness from the statement itself, we'd need to know who the cleric is, and if we know that, we've already solved the problem.
I solved this in a similar way but with a slightly different perspective. Step 1: Assume Cedar is the cleric (same as your solution), which doesn't work and therefore Cedar can't be the cleric. Step 2: Assume Beorn is the cleric and Agan is lying. Since Agan is lying, that must mean Beorn DID 'drink a lying potion' AND 'is a cleric'. Beorn's statement must then be a lie, but that's contradictory as the core assumption here self-evidently makes what Beorn is claiming the truth. This rules out half of all options where Beorn is the cleric. Step 3: Assume Beorn is the cleric and Agan is telling the truth. Since Agan is telling the truth, that means 'Beorn drank a lying potion' is false. Beorn's statement must then be the truth, but that's contradictory because 'Agan drank a lying potion' is false, and 'Beorn is not a cleric' is also false. This rules out the rest of the options where Beorn is the cleric. By process of elimination, Agan is the cleric. I think this is more straightforward because all steps have "assume X is the cleric" as their starting point. From there it's just checking whether a contradiction arises.
I think you’re right about this [see initial comment] being the most efficient, up until step 3. To recap, the statements are: A - B is not both lying and a cleric. B - Either A is lying or I am not a cleric. C - The cleric is lying. My starting point was to look at whether C is lying or telling the truth (which is perhaps the natural way of approaching logic problems like these). In either case, C couldn’t be the cleric. Next, I used the same step of assuming A is lying, having noted that it makes the first part of B’s statement true. This leads to the contradiction you mentioned, so A is telling the truth. Now for step 3. The simplest approach is to look at B’s possibilities, since A’s and B’s statements refer mainly to B, while we know the other part i.e. A is not lying. If B is telling the truth, the 2nd part of his statement is true and he is not the cleric. Otherwise, B is lying and A’s statement says he is not the cleric. In both cases, A is the cleric.
Yeah, when I was working out the logic on paper, I boiled it down to A: B != (L && Cl) B: A = L XOR B! = C C: Cl = L If A = L, then B = Cl && B = L If B = L, then A != L XOR B != Cl CONTRADICTION Therefore A = T I wasn’t good enough to go further.
My family and I also used a different step 2 and 3. Step 1: Cedar is not cleric. Step 2: Assume Bjorn is cleric and telling the truth. Find out it's impossible. Step 3. Assume Bjorn is cleric and is lying. Find out it's impossible. Conclusion: Bjorn and Cedar are not the cleric. Didn't even have to figure out who was lying or truthing.
I’ve seen many Ted riddles over the years and this is the first I actually paused to attempt to solve and amazingly I did exactly the correct thing as the explanation. Also I did it in my head quickly so from an outside perspective a person would see me pause the video and stare into space motionless for a minute before suddenly shouting “Agan is the Cleric 100%”
Step 1: Tell them “at least two of you have green eyes” Step 2: Being perfect logicians, they will deduce that they all have green eyes after no one leaves on the first night Step 3: Give Agan some of your treasure as a gift when she leaves on the second night Step 4: Repeat steps 1 and 2 every Monday
This was a fun riddle, but I think one thing that could be made clearer is that Beorn's statement is an exclusive or (although I believe it's still solvable if it is an inclusive or). Generally, "either... or..." is still an inclusive or in logic, even though colloquially it's thought of as exclusive or.
It turns out it doesn't matter, because Cedar's statement is actually a paradox if there isn't at least 1 liar and 1 truth-teller in the group (i.e., if all of them are liars or if all of them are truth-tellers). So once you work out that Agan and Beorn's statements are internally consistent no matter what operator you use (OR or XOR), and either both of them are liars or both of them are truth-tellers, you know Cedar can't be a truth-teller if both Agan and Beorn are liars. So Cedar has to be the liar, Agan and Beorn both have to be truth-tellers, and you can work out who the cleric is from their statements. If you follow that logic chain, you never get into a situation where Beorn's claim evaluates to (true X/OR true) and never have to worry about which operator it is. I thought it was very clever puzzle design, making the OR/XOR not matter, until I watched the video and they apparently based their whole solution around XOR...
Not to mention, they didn't actually state that there weren't three truth potions or three lying potions. We were left to assume that wasn't a possibility.
@@zUJ7EjVDyou don’t need to be told that they drank some of each potion, because their statements would be contradictory if they were all true or all false
The most I managed to work out was that Cedar's statement meant that they couldn't all have drunk the same kind of potion and that Cedar couldn't be the cleric, but beyond that I was stuck
I found an easier way of thinking about this one involving checking each possible person to be the cleric. Also, Agan's statement can be reworded more clearly; NOT (A AND B) is the same as (NOT A) OR (NOT B), so Agan's statement can be recast as "Either Beorn is T or Beorn is not a cleric". If Cedar is the cleric, his statement is basically "I am lying", which is a contradiction, so he can't be the cleric. If Beorn is the cleric, both his and Agan's statements have an "or Beorn is not the cleric" clause that can be dropped (since A OR false is the same as A). So Beorn says Agan is lying while Agan says Beorn is telling the truth, which is also a contradiction. If Agan is the cleric, everything works. Agan and Beorn are both telling the truth since Beorn isn't the cleric, and Cedar is lying about Agan. So this is the only one that works, and Agan must be the cleric. Edit: I interpreted either/or as being OR rather than XOR (both can be true in OR), but it didn't matter.
I like how this riddle effectively explains why the clues aren't clear or direct. The potions compel them to answer with either the truth or a lie, but don't compel clear or precise answers, and they obviously don't want you to know which is the cleric, so they're going to make it as unclear as they can.
I enjoyed this one. I found some annoyance at the wording, particularly that it's hard to figure out exactly what part of B's statement could actually be the lie. It felt good that you called this out specifically. I didn't quite make the 10 minute timer but I got the answer in the end. Thanks for another fun one!
The announcement of Ted games is really exciting! Been watching your videos for half a dozen years or more, and it sounds like the perfect way to see if I retained some of this awesome knowledge:)
This is the first one I’ve actually solved! I went by process of elimination. C couldn’t be the cleric, so I went through every combination of truth/lying and there was no combination where B could be the cleric
Cedar doesn't give any information other than her not being the cleric though. Once we rule her out, the only "info" she gives is that the cleric has either drank a truth or lying potion, ... which really doesn't say anything. You don't need her to finish the riddle.
I read Beorn's statement as an inclusive or and am rather bamboozled by the reading that it's an exclusive or, but this is a nice puzzle where either interpretation gets you the right answer. That way the focus is on the logic and not the exact way you formalize a natural language either/or statement. Thanks, Raymond Smullyan! If I bet someone $5 that "Either most ducks have wings or most ducks have feathers" was false and they took me up on it, I don't think "Ahah! But most ducks have *both* wings and feathers!" would get me the $5.
I started by going off of Agan's statement, since the "and" seemed more restrictive. What I got seems to be (to me) a simpler solution. Here is my write-up: *Statements for reference:* Agan: _Beorn is not both a lying-potion drinker and a cleric._ Beorn: _Either Agan drank a lying-potion or I am not a cleric._ Cedar: _The cleric drank a lying-potion._ *The solution:* 1. Assume Agan drank a lying-potion: Agan Beorn Cedar Lying? Y Cleric? 2. By Agan's (lying) statement, Beorn is both a lying-potion drinker and a cleric. Agan Beorn Cedar Lying? Y Y Cleric? Y 3. However, Beorn's (lying) statement is true, as Agan drank a lying-potion. So, (by contradiction) Agan must have drunk a truth-potion. Agan Beorn Cedar Lying? X Cleric? 4. Assume Beorn drank a lying-potion. By Agan's (truthful) statement, Beorn is then not a cleric. Agan Beorn Cedar Lying? X Y Cleric? X 5. However, Beorn's (lying) statement is true, as Beorn is not a cleric. So, (by contradiction) Beorn must have drunk a truth-potion. Agan Beorn Cedar Lying? X X Cleric? 6. By Beorn's (truthful) statement, Beorn is not a cleric. Agan Beorn Cedar Lying? X X Cleric? X 7. If Cedar is telling the truth, there is no cleric because everyone drank a truth-potion. So, Cedar must be lying, making Agan the cleric. Agan Beorn Cedar Lying? X X Y Cleric? Y X X Interestingly, Beorn's statement of exclusivity was not a factor in determining this solution, which is nice because I wasn't sure how to interpret it when solving this puzzle. However, I assume part of the idea behind this puzzle is to expose people to exclusive-or operations.
This is a nice twist on the original riddle, since the solution to that is quite simply asking one of the two what the other's answer would be and choosing the opposite regardless of if you know which is the liar or truth teller.
Oh, I solved this one on my own! I went through every option of truth or lie to find the contradictions and basically solved it in a way more complicated way.
Cedar's statement isn't actually necessary to solve this riddle after we realise they cannot be the cleric. Assuming there is only one cleric (which is given), Agan and Beorn's statements alone are enough to determine which is the cleric. T and T - forces Agan to be the Cleric. All other options (TF, FT, FF) get some contradiction between the two statements, regardless of Cedar's, so they are impossible under the rules of the riddle.
De Morgan's theorem saved me this time. That's the one where if you apply a negative to an AND or OR statement, it switches. In other words, ~(A and B) = ~A or ~B, and ~(A or B) = ~A and ~B. It doesn't really apply to A's statement, because that was the exclusive or, but... wait I think I did the wrong math but got the right answer.
This video is really good. Keep up the good work! Edit: I was looking on his channel then I saw a new video that he posted 56 seconds ago, and I am mediately clicked on it Edit 2: I love your channel
As far as I can tell, assuming that we define A "lying" as meaning that BOTH his propositions are in fact true, while B "lying" means that either BOTH OR NEITHER of his propositions is false, then: (spoiler) 1. A and B are both telling the truth; 2. B is not the cleric; 3. This would create a Liar's Paradox if C was the cleric, so 4. The cleric must be A (and thus 5: C is lying).
Solved it by drawing a tree diagram inspired system feel proud of myself because ted riddles are hard in my opinion but when you solve it it feels so rewardig
I started with Beorn, figuring that that was a response that had both straightforward consequences and gave a lot of information due to specificially pointing at one person (Agan). After that, I just went through the possible options. 1 (Beorn telling the truth, first statement true) : "Agan drank a Lying Potion, and also I am the Cleric." -- If this is true, then going over to Agan, her statement becomes "Beorn is a lying Cleric." But we started this whole thing assuming that Beorn was speaking the truth, so that's a contradiction. This route must be false. 2 (Beorn telling the truth, second statement true): "Agan drank a Truth Potion, and also I am not the Cleric." -- Going over to Agan again, her statement now has a few scenarios. However, if the "Beorn is a cleric" part would be true, then that is again a contradiction. So instead let's focus on the other option, namely "Beorn drank a Truth Potion, and is not the Cleric." Okay, this one makes perfect sense and doesn't contradict itself. In our current version, Agan is telling the truth and is a Cleric, while Beorn is telling the truth and is *not* the Cleric. Assuming for a moment that at least one person is lying, this should then be Cedar. Cedar's statement is that the Cleric drank a Lying Potion, which would itself be a lie in our current setup. Okay, everything checks out! For the sake of completion though, let's check out the other options first. 3 (Beorn lying, both true): "Agan drank a Lying Potion, and also I am not the Cleric." -- Agan's response now immediately causes issue, because in this scenario it is true that Beorn is not the Cleric. 4 (Beorn lying, both false): "Agan drank a Truth Potion, and also I am the Cleric." -- Now we run into the exact opposite issue, with Agan's response being a lie while it is supposed to be the truth. In conclusion, only option 2 does not run into any contradictions, and therefore must be the proper solution. Agan is the Cleric.
I was momentarily tripped up by Agan and Beorn seeming impossible to resolve. It would have been interesting to mention this fact that although Agan says Beorn can't be both of something, he doesn't have to be one or the other. He can be neither. Whereas Beorn uses the opposite logic forcing the in X OR logic gate that both of Beorn's statements are true or neither of them. I eventually caught this, but that threw me for a loop momentarily and had me running in circles until I focused on narrowing it down and excluding the option that they ended up suggesting in the solution. It's always best to start with the simple and work towards the confusing people. Lesson learned lol
I’m usually pretty good with logic puzzles. But this one straight up broke my brain. I would just randomly put the ring on one of them and hope for the best.
2:43 If Agan is lying I think Beorn can also be a truth-telling cleric or lying non-cleric In Boolean algebra, inverse of ~(A and B) is A or B Not the “A and B” Of course, Beorn can still be lying cleric, it just cut out the scenario where Beorn is truth-telling non-cleric
Step 1- Ask them all individually "Did you drink a potion?" And since I know they all did I can eliminate the ones that say no. Step 2- The ones that say yes I will ask "are you the cleric?" And should get my awnser. Step 3- I turn them into worms for 3 days to get my point across.
I mismatched Beorn and Agan while working it out myself, but I got to the same Cedar conclusion of “False Potion and Not a Cleric”. I did good, but not good enough to save myself from the Cleric.
*SPOILER* the solution could have saved some hassle - Cedar's statement has no bearing on the other two characters. You can just wipe his column from the board and only care about the remaining two statements. At the same time I object to the assumption that "A or B" implies "not A and B", it was or and not xor. The lack of specificity means we have to assume the more general statement that Beorn meant "Either Fact 1, or Fact 2, or Both". The problem is still solvable though, it just means one extra set of conditions on Beorn's statement. Thank you for listening to my TED talk.

There's a simpler way of solving this:
Step 1: Assume Cedar is the cleric.
Then his statement is equivalent to 'I am lying', which is self-contradictory.
Thus, Cedar is not the cleric.
Step 2: Assume Agan is lying.
Then Beorn must be both a liar and the cleric. But then, 'Agan drank a lying potion' is true and 'I am not a cleric' is false, making Beorn's either-or statement correct, which contradicts him being a liar.
Thus Agan must be telling the truth.
Step 3: Assume Beorn is lying.
Then, per Agan's statement, which from step 1 we know to be true, he cannot also be the cleric. But then, 'Agan drank a lying potion' is false and 'I am not a cleric' is true, making Beorn's either-or statement correct, which contradicts him being a liar.
Thus Beorn must be telling the truth.
Step 4: We know from step 3 that Beorn is telling the truth, and we know from step 2 that Agan didn't drink the lying potion, so the 'I am not a cleric' part of the either-or statement must be the true part. Thus, one of the other two must be the cleric. And per step 1, we know it isn't Cedar, so that leaves Agan as the Cleric by process of elimination.
The truthfulness of Cedar's statement is irrelevant to the solution, so ignoring it leads to simpler logic. Just thinking about the problem for a bit makes this obvious: none of the other statements refer to Cedar at all, so we can't determine its truthfulness from them. And in order to determine its truthfulness from the statement itself, we'd need to know who the cleric is, and if we know that, we've already solved the problem.

I think this is more straightforward because all steps have "assume X is the cleric" as their starting point. From there it's just checking whether a contradiction arises.
I think you’re right about this [see initial comment] being the most efficient, up until step 3.
To recap, the statements are:
A - B is not both lying and a cleric.

C - The cleric is lying.
My starting point was to look at whether C is lying or telling the truth (which is perhaps the natural way of approaching logic problems like these). In either case, C couldn’t be the cleric.
Next, I used the same step of assuming A is lying, having noted that it makes the first part of B’s statement true. This leads to the contradiction you mentioned, so A is telling the truth.
Now for step 3. The simplest approach is to look at B’s possibilities, since A’s and B’s statements refer mainly to B, while we know the other part i.e. A is not lying. If B is telling the truth, the 2nd part of his statement is true and he is not the cleric. Otherwise, B is lying and A’s statement says he is not the cleric. In both cases, A is the cleric.
Yeah, when I was working out the logic on paper, I boiled it down to
A: B != (L && Cl)
B: A = L XOR B! = C
C: Cl = L
If A = L, then B = Cl && B = L
If B = L, then A != L XOR B != Cl
CONTRADICTION
Therefore A = T
I wasn’t good enough to go further.
My family and I also used a different step 2 and 3.
Step 1: Cedar is not cleric.
Step 2: Assume Bjorn is cleric and telling the truth. Find out it's impossible.
Step 3. Assume Bjorn is cleric and is lying. Find out it's impossible.
Conclusion: Bjorn and Cedar are not the cleric. Didn't even have to figure out who was lying or truthing.
Last time I was this early, the people still didn’t know who had green eyes.

Congrats on finding this video within 99 days
TED-Ed riddles are a master class in making the story framing as much of a nonsequitur from the original puzzle as possible :D
I’ve seen many Ted riddles over the years and this is the first I actually paused to attempt to solve and amazingly I did exactly the correct thing as the explanation. Also I did it in my head quickly so from an outside perspective a person would see me pause the video and stare into space motionless for a minute before suddenly shouting “Agan is the Cleric 100%”
That ending was so uncalled for
How dare you! Lich x Agan is OTP!
0:15 I like the fabrecire eggs from the egg drop riddle and the crystals from the fire crystal riddle
dont forget about the gems from the dongle’s difficult dillema riddle
probably the only ted ed riddle i could solve man
"temporarily, of course; you're not a monster" 💀
Polymorph ends in: 59 minutes
Step 1: Tell them “at least two of you have green eyes”
Step 2: Being perfect logicians, they will deduce that they all have green eyes after no one leaves on the first night
Step 3: Give Agan some of your treasure as a gift when she leaves on the second night
Step 4: Repeat steps 1 and 2 every Monday
uhh, wrong riddle there buddy

This was a fun riddle, but I think one thing that could be made clearer is that Beorn's statement is an exclusive or (although I believe it's still solvable if it is an inclusive or). Generally, "either... or..." is still an inclusive or in logic, even though colloquially it's thought of as exclusive or.
It turns out it doesn't matter, because Cedar's statement is actually a paradox if there isn't at least 1 liar and 1 truth-teller in the group (i.e., if all of them are liars or if all of them are truth-tellers). So once you work out that Agan and Beorn's statements are internally consistent no matter what operator you use (OR or XOR), and either both of them are liars or both of them are truth-tellers, you know Cedar can't be a truth-teller if both Agan and Beorn are liars. So Cedar has to be the liar, Agan and Beorn both have to be truth-tellers, and you can work out who the cleric is from their statements. If you follow that logic chain, you never get into a situation where Beorn's claim evaluates to (true X/OR true) and never have to worry about which operator it is. I thought it was very clever puzzle design, making the OR/XOR not matter, until I watched the video and they apparently based their whole solution around XOR...
Not to mention, they didn't actually state that there weren't three truth potions or three lying potions. We were left to assume that wasn't a possibility.
@@zUJ7EjVDyou don’t need to be told that they drank some of each potion, because their statements would be contradictory if they were all true or all false
Oh wow. I actually solved one. And my thought process was nearly identical to the explanation in the video. I'm gonna give myself a cookie.
0:29 Accurate depiction of DnD 5e Clerics (probably):
The most I managed to work out was that Cedar's statement meant that they couldn't all have drunk the same kind of potion and that Cedar couldn't be the cleric, but beyond that I was stuck
"They drank either a truth or lying potion"
Finally a riddle I can solve give me 30 minutes.
Being a coder and thus knowing logic gates and truth tables inside and out definitely helped with this one.
I solved it myself in just 5 minutes, and the moment the narrator mentioned the XOR, I felt like a god
5 min AND NEW RIDDLE??? WE BEING FED
I found an easier way of thinking about this one involving checking each possible person to be the cleric. Also, Agan's statement can be reworded more clearly; NOT (A AND B) is the same as (NOT A) OR (NOT B), so Agan's statement can be recast as "Either Beorn is T or Beorn is not a cleric".
If Cedar is the cleric, his statement is basically "I am lying", which is a contradiction, so he can't be the cleric.
If Beorn is the cleric, both his and Agan's statements have an "or Beorn is not the cleric" clause that can be dropped (since A OR false is the same as A). So Beorn says Agan is lying while Agan says Beorn is telling the truth, which is also a contradiction.
If Agan is the cleric, everything works. Agan and Beorn are both telling the truth since Beorn isn't the cleric, and Cedar is lying about Agan. So this is the only one that works, and Agan must be the cleric.
Edit: I interpreted either/or as being OR rather than XOR (both can be true in OR), but it didn't matter.
I love how you both explain the problem and solve it in almost half the time you stated the necromancer to have
Beorn's statement is true no matter what, he's just spitting logical conclusion about Agan's statement
4:53 “Temporarily, of course, you’re not a monster.”
Proud to announce this as the first Ted-Ed riddle I've figured out 100% on my own
Nice
I like how this riddle effectively explains why the clues aren't clear or direct. The potions compel them to answer with either the truth or a lie, but don't compel clear or precise answers, and they obviously don't want you to know which is the cleric, so they're going to make it as unclear as they can.
The real dungeon master's riddle: can everyone make it next Friday?
I enjoyed this one. I found some annoyance at the wording, particularly that it's hard to figure out exactly what part of B's statement could actually be the lie. It felt good that you called this out specifically. I didn't quite make the 10 minute timer but I got the answer in the end. Thanks for another fun one!
First time getting a riddle right with 0 help! Celebration time!
I love how you included the martial-caster divide in this. Heavily exaggerated ofc.
Perfect timing, I was just looking for a good puzzle to throw at my DnD party. This will work perfectly
The announcement of Ted games is really exciting! Been watching your videos for half a dozen years or more, and it sounds like the perfect way to see if I retained some of this awesome knowledge:)
I wish there was a huge crossover of every riddle character having a party 🥳🎉
i agree
ted ed if u read comments pls do the crossover
This is the first one I’ve actually solved! I went by process of elimination. C couldn’t be the cleric, so I went through every combination of truth/lying and there was no combination where B could be the cleric
Cedar doesn't give any information other than her not being the cleric though.
Once we rule her out, the only "info" she gives is that the cleric has either drank a truth or lying potion, ... which really doesn't say anything.
You don't need her to finish the riddle.
close enough, welcome back 3 gods riddle
I read Beorn's statement as an inclusive or and am rather bamboozled by the reading that it's an exclusive or, but this is a nice puzzle where either interpretation gets you the right answer. That way the focus is on the logic and not the exact way you formalize a natural language either/or statement. Thanks, Raymond Smullyan!
If I bet someone $5 that "Either most ducks have wings or most ducks have feathers" was false and they took me up on it, I don't think "Ahah! But most ducks have *both* wings and feathers!" would get me the $5.
I started by going off of Agan's statement, since the "and" seemed more restrictive. What I got seems to be (to me) a simpler solution. Here is my write-up:
*Statements for reference:*
Agan: _Beorn is not both a lying-potion drinker and a cleric._
Beorn: _Either Agan drank a lying-potion or I am not a cleric._
Cedar: _The cleric drank a lying-potion._
*The solution:*
1. Assume Agan drank a lying-potion:
Agan Beorn Cedar
Lying? Y
Cleric?
2. By Agan's (lying) statement, Beorn is both a lying-potion drinker and a cleric.
Agan Beorn Cedar
Lying? Y Y
Cleric? Y
3. However, Beorn's (lying) statement is true, as Agan drank a lying-potion. So, (by contradiction) Agan must have drunk a truth-potion.
Agan Beorn Cedar
Lying? X
Cleric?
4. Assume Beorn drank a lying-potion. By Agan's (truthful) statement, Beorn is then not a cleric.
Agan Beorn Cedar
Lying? X Y
Cleric? X
5. However, Beorn's (lying) statement is true, as Beorn is not a cleric. So, (by contradiction) Beorn must have drunk a truth-potion.
Agan Beorn Cedar
Lying? X X
Cleric?
6. By Beorn's (truthful) statement, Beorn is not a cleric.
Agan Beorn Cedar
Lying? X X
Cleric? X
7. If Cedar is telling the truth, there is no cleric because everyone drank a truth-potion. So, Cedar must be lying, making Agan the cleric.
Agan Beorn Cedar
Lying? X X Y
Cleric? Y X X
Interestingly, Beorn's statement of exclusivity was not a factor in determining this solution, which is nice because I wasn't sure how to interpret it when solving this puzzle. However, I assume part of the idea behind this puzzle is to expose people to exclusive-or operations.

Yay!! More riddles, I love these to just listen to and sometimes try my hand at shoveling them. Please do more.
Using the liar paradox to make people ignore C and to obscure C might be lying, this is a brilliant riddle.
Must be during holiday season, otherwise groups of adventurers usually break into lairs rather between friday afternoon and sunday😀
This is the earliest I've been in a Ted-Ed video
Me too lol
Lol yeah the recommendations I usually get from the algorithm are from 5 years ago.
This is actually the first TED-Ed riddle I've ever gotten 😭
FINALLY all my years of study computer science has paid off!
FINALLY all my years of DMing have paid off!
This is a nice twist on the original riddle, since the solution to that is quite simply asking one of the two what the other's answer would be and choosing the opposite regardless of if you know which is the liar or truth teller.
Oh, I solved this one on my own! I went through every option of truth or lie to find the contradictions and basically solved it in a way more complicated way.
Cedar's statement isn't actually necessary to solve this riddle after we realise they cannot be the cleric. Assuming there is only one cleric (which is given), Agan and Beorn's statements alone are enough to determine which is the cleric.
T and T - forces Agan to be the Cleric.
All other options (TF, FT, FF) get some contradiction between the two statements, regardless of Cedar's, so they are impossible under the rules of the riddle.
I had a passing thought halfway through the riddle, "what if romance lol" and it actually happened fr? Crazy (not complaining tho, gimme sequel)
The correct answer is that the dungeon master is playing with the other players, not against them
so Agan's plan is well executed, congrats Agan for the engagement
Beorn was the MVP of that team trying to confuse us with the XOR statement...still solved it when I realized it was an XOR and not an OR lol
Spoilers:
We know who the cleric is, but I am going to guess Beorn is the rogue because he is the one who swiped the cursed skull without checking.
And Cedar is the fighter, not really overthinking about the answer they give, talking is for weaklings anyway.
Ted Ed watched Kenadian's parody video and said "yeah, let's do something like that"
De Morgan's theorem saved me this time. That's the one where if you apply a negative to an AND or OR statement, it switches.
In other words, ~(A and B) = ~A or ~B, and ~(A or B) = ~A and ~B.
It doesn't really apply to A's statement, because that was the exclusive or, but...
wait I think I did the wrong math but got the right answer.
Proud to say I paused the video, and thought for a while and then shouted out
"IT'S AGAN!"
in a middle of food court full of people
This is like the magic crystal riddle with one less person.
Another riddle by TED-Ed!
I like these types of puzzles. They are both simple and complex at the same time. Had fun working through it on my own. :)
This video is really good. Keep up the good work!
Edit: I was looking on his channel then I saw a new video that he posted 56 seconds ago, and I am mediately clicked on it

Not sure who writes these story beats for the riddles but they make me smile 😊
I like that the Lich doesn’t seem to be a complete villain and seems like he is just trying to defend his minions and treasure.
I ACTUALLY SOLVED THIS ONE! As a fourteen year old I'm very happy.

Oh wow this was the first Ted-Ed riddle I've solved!
Thanks for making this, kudos to you, Ted-Ed.
you know kudos is a currency in a battle royale game called fall guys
First *that* video on *that* site and now a Ted Ed riddle about DND? These are good times.
As far as I can tell, assuming that we define A "lying" as meaning that BOTH his propositions are in fact true, while B "lying" means that either BOTH OR NEITHER of his propositions is false, then:
(spoiler)
1. A and B are both telling the truth; 2. B is not the cleric; 3. This would create a Liar's Paradox if C was the cleric, so 4. The cleric must be A (and thus 5: C is lying).
Even TED-Ed knows that only spellcasters pose a legitimate threat to high-level villains.
I was expecting "Frostmourne Hungers" as the video quote.
I've been waiting for another riddle! Huzzah!
Y’all, I got this one right before the countdown to figure it out by pure luck, and I’m still very proud of myself.
Solved it by drawing a tree diagram inspired system feel proud of myself because ted riddles are hard in my opinion but when you solve it it feels so rewardig
I didn't expect that ending with the necromancer giving the ring 🗿
I started with Beorn, figuring that that was a response that had both straightforward consequences and gave a lot of information due to specificially pointing at one person (Agan). After that, I just went through the possible options.
1 (Beorn telling the truth, first statement true) : "Agan drank a Lying Potion, and also I am the Cleric." -- If this is true, then going over to Agan, her statement becomes "Beorn is a lying Cleric." But we started this whole thing assuming that Beorn was speaking the truth, so that's a contradiction. This route must be false.
2 (Beorn telling the truth, second statement true): "Agan drank a Truth Potion, and also I am not the Cleric." -- Going over to Agan again, her statement now has a few scenarios. However, if the "Beorn is a cleric" part would be true, then that is again a contradiction. So instead let's focus on the other option, namely "Beorn drank a Truth Potion, and is not the Cleric." Okay, this one makes perfect sense and doesn't contradict itself. In our current version, Agan is telling the truth and is a Cleric, while Beorn is telling the truth and is *not* the Cleric. Assuming for a moment that at least one person is lying, this should then be Cedar. Cedar's statement is that the Cleric drank a Lying Potion, which would itself be a lie in our current setup. Okay, everything checks out!
For the sake of completion though, let's check out the other options first.
3 (Beorn lying, both true): "Agan drank a Lying Potion, and also I am not the Cleric." -- Agan's response now immediately causes issue, because in this scenario it is true that Beorn is not the Cleric.
4 (Beorn lying, both false): "Agan drank a Truth Potion, and also I am the Cleric." -- Now we run into the exact opposite issue, with Agan's response being a lie while it is supposed to be the truth.
In conclusion, only option 2 does not run into any contradictions, and therefore must be the proper solution. Agan is the Cleric.
One of the few puzzles I actually paused to solve. It was a lot easier when I started writing things down.
I was momentarily tripped up by Agan and Beorn seeming impossible to resolve. It would have been interesting to mention this fact that although Agan says Beorn can't be both of something, he doesn't have to be one or the other. He can be neither. Whereas Beorn uses the opposite logic forcing the in X OR logic gate that both of Beorn's statements are true or neither of them. I eventually caught this, but that threw me for a loop momentarily and had me running in circles until I focused on narrowing it down and excluding the option that they ended up suggesting in the solution. It's always best to start with the simple and work towards the confusing people. Lesson learned lol
I’m usually pretty good with logic puzzles. But this one straight up broke my brain. I would just randomly put the ring on one of them and hope for the best.
2:43
If Agan is lying
I think Beorn can also be a truth-telling cleric or lying non-cleric
In Boolean algebra, inverse of ~(A and B) is A or B
Not the “A and B”
Of course, Beorn can still be lying cleric, it just cut out the scenario where Beorn is truth-telling non-cleric
Step 1- Ask them all individually "Did you drink a potion?" And since I know they all did I can eliminate the ones that say no.
Step 2- The ones that say yes I will ask "are you the cleric?" And should get my awnser.
Step 3- I turn them into worms for 3 days to get my point across.
Realistically the classes of each should be pretty obvious based on their gear and stuff
could've just asked "yes or no: are you the cleric?" to each one, but this works too ig
Yo! New riddle!
Listen, you may have even worse mondays, but imagine the pain of the weekend boss, sundays and saturdays are working days! horrific!
FINALLY, MY ANSWER IS RIGHT, FOR ONCE!!!
If I ever become a lich I'm using EXCLUSIVELY truth potions in my traps.
I mismatched Beorn and Agan while working it out myself, but I got to the same Cedar conclusion of “False Potion and Not a Cleric”.
I did good, but not good enough to save myself from the Cleric.
Cleric definitely multiclassed as an Eloquence Bard
I hate that I intuitively got the right answer, but spent ten minutes trying to reason out why I knew the Cleric was the Cleric, without success.
*SPOILER* the solution could have saved some hassle - Cedar's statement has no bearing on the other two characters. You can just wipe his column from the board and only care about the remaining two statements. At the same time I object to the assumption that "A or B" implies "not A and B", it was or and not xor. The lack of specificity means we have to assume the more general statement that Beorn meant "Either Fact 1, or Fact 2, or Both". The problem is still solvable though, it just means one extra set of conditions on Beorn's statement. Thank you for listening to my TED talk.
