Rabi-Ribi: Irisu SP (Right Side) on BEX [No Consumables/Buffs] - *BEX’S GRAND FINALE*

Irisu SP beaten on BEX. PLEASE pay attention, because I am not doing this again...Or at least thats what I would like to say, but a certain Cocoa related achievement means I will unfortunately have to do this fight at least 1 more time...[WARNING: Contains Rant inside]
...Or at least there used to be one, but the rant got so big it surpassed the amount of characters TH-cam allows in its description xD.
If you REALLY want to (You dont), you can read the full, original version here:
pastebin.com/S...
But the short, summarized & somewhat more positive version (A bit less salty about it than back when I wrote the original) is:
Fight is frustrating in general- it has a ton of stuff thats not blind/1st try friendly, Rank LOVES to constantly drop the SECOND you stop attacking Irisu (4:42 & 11:40 are great examples), theres a couple of times it is downright cheap/unfair, and the entire thing just seems to be designed in order to be as annoying as possible.
Miru SP was also really really hard at first but it never felt nearly as frustrating as this, nor I ever believed it was being cheap/unfair. It wasnt annoying, and I had fun pretty much the entire time I was learning it. I honestly cant claim the same for this fight.
1st Phase: The worst. Filled with either unfun "Trick" attacks that are either impossible and you get hit by them 3+ times, or hilariously easy and trivial when you know the trick, absolutely no in-between.
NOT a good phase. The faster you skip it, the better.
And you can do so with the Amulet Regen trick at the very start. Follow my exact steps in the video at the very beginning and you will see how to skip most of it.
I am very glad I found this to be honest, because by skipping the worst part it made the fight more fun.
2nd Phase: Very hard, but not too annoying, for the most of the part. Some fun innovations on the original attacks!
You really want to damage Irisu every single time she lands. You HAVE to in fact.
My one complaint is the Mortality Debuff Ring at the very end of the phase.
Theres zero excuses for this. Completely unnecesary BS cheap move that seems straight from a troll game (You know the type, IWBTG games and such- Although even those hardly insta-kill runs after spending 10 MINUTES on it).
Miru SP didnt need to resort to such BS to be a difficult boss.
3rd Phase: Fairly good for the most of the part. Probably the best part. I dont understand most of this stuff but I havent reached it enough times to really tell if they are broken or I am doing it wrong, so I will default to the later...
Very rarely you may get the Instant Death effect for no apparent reason. This happened to me on 3-4 occasions. I am sure there IS a reason for this to happen and its not actually random, but it doesnt changes the fact that theres a fair chance you may just get insta killed from nowhere and NOT EVEN KNOW WHY, and thats hardly good design.
I swear its for things like this I cant fully enjoy this fight. Too many.. questionable design choices...
Everything from 11:45 onwards was done completely blind- as in, it was the first time I ever saw these attacks so I had zero clue on what to do. That also includes the following phase (!)...
Endurance: I-I dont even know...
I just prayed and tried my best to dodge and... I managed to survive it all 1st try somehow O_o. I wasnt expecting to win at all, I was just merely trying to learn exactly what was going on at the time for the next attempt(s) that got here. Cute ending.
So... did I ultimately enjoy the fight?
I am honestly not very sure myself. At times I hated it. Other times I had fun with it.
Towards the end especially, I had some sort of Stockholm Syndrome and started to accept/enjoy it all, annoying/cheap stuff included.
One thing is for sure though:
At 15 hours of attempts, THIS is officially the hardest challenge I have ever done in Rabi-Ribi- I know I have said that a couple of times in the past already in some other of my older clears, but this time is for real- After all, BEX is over, theres no other boss left to dispute Irisu SP’s place as the Hardest Boss in the game.
She was also one of the most rage-inducing bosses in my entire gaming career. For better or worse...
I think this was an ultimately good experience, but I dont think I liked it enough to want a rematch any time soon... except I will have to return to it with Cocoa ... :/
Miru SP is a challenging fight, but its a well-done fight.
Irisu SP is the hardest boss in the game, yes, but perhaps not for all the right reasons.
/Rant
Still love this game, and consider it as one of the best games I have ever played- Just, not particulary because of this boss fight, ok?
...I hope Cocoa is well-prepared and ready for this hell. Because I am not.
Get Rabi-Ribi here!

Also while the title claims it is the end of BEX (And, officially, it IS), I may or may not have a couple of bonus projects on my mind left...

You know, looking back, out of all the things I have done on Rabi-Ribi... THIS, is the one that brought the most joy to me.
It is *not* the hardest thing I have done by any means, but it is definitely the challenge that was the most exciting to overcome.
When I beat this, It felt *so good* - I legit screamed at 14:40 - which I never do, I am usually just mute while playing - because I couldn’t believe it. I just couldn’t. After 15 hours... It was _OVER_ ...
Nothing has come close to replicate this moment. Not Rabi, nor other games. Some can come close, but so far, I think this is the #1 happiest moment I have ever been beating a challenge.

[@flariz4824]

lmfao the rant is hilarious and kinda embarassing but jeez I was legimately so angry back then

[@sgnrnecron]

Thanks a lot for this video, it helped me defeat lvl 500+ Irisu for the achievement.
I wasn't able to replicate that insane combo you did at the beginning (especially jumping and drilling down without letting the boss escape the combo) but spamming boosts and amulets to extend the combo and using bunny memories to block the debuffs still helped me doing some significant damage at the start.
After seeing your item page, I also disabled Water Orb, Wall Jump, Bunny Roll and Max Bracelet, which lowered the level of the boss from 510 to 500 and disabled max boost.
I wasn't totally convinced by your badges configuration at first, but that's also what worked in the end. I even finished with 1 cake and 3 donuts left.
For anyone trying to do that achievement too, you can do this in Hard difficulty. Just make sure to (re)defeat the Halloween boss and SP Saya AFTER your last Irisu fight (cause they reset) or Irisu SP won't reach lvl 500+ on the right path. Try to remember to block the Mortality debuff in the middle of the fight. Good luck.

[@ApolloHoaxTheory]

That stunlock at the beginning tho...

[@flariz4824]

And even with that, this is *still* the hardest boss fight in the entire game by far.
Also, that is pretty okay considering I am not using Buffs, with buffs it’s even possible to do this:

[@FirebunbunYT]

@@flariz4824 The part I don't understand is why you aren't using bunny amulet charges?

[@flariz4824]

@@FirebunbunYT That’s especific to this fight only, it’s seemingly a bug where you don’t use up amulet charges during the first few frames of the fight. Idk if it still works maybe it was patched.

[@TouhouManiaSky]

How much practice does it take to skip the entirety of the first phase jesus
Well learned some tricks to hopefully help me on this fight T-T

[@flariz4824]

Once you get the trick, it’s not *that* bad to execute it most of the time, and if you don’t get it luckily you can just quickload and barely any time was lost.
Also, if you use Buffs, you might want to look at what is possible with them:

Personally, I recommended using the Amulet shortcut key (Default is Shift if I am not wrong) since it seems more consistent, at least to me it was.

[@chris1cc]

How do you do that stunlock combo at the start? I've seen a couple videos of it and I still can't get it down.

[@flariz4824]

It is fairly difficult to get it down, you have to be fairly fast and probably reset it quite a bit. Something that really helps is if you maintain the Quick Amulet button pressed *before* the proper fight begins, in the cutscene I am already holding it so as soon as the actual fight starts, Erina inmmediately uses an Amulet in order to stun Irisu literally the first possible frame.

[@chris1cc]

@@flariz4824 Thanks for the tip, I'll make sure to try it out next time since I was actually able to clear this fight not too long ago.

[@endless2178]

what is different left side or right side ?

[@flariz4824]

Pretty sure on Left Side, aside from being a lower level, she also lacks certains buffs cush as X2 damage and the +1 Attack Boost (Which basically enchances pattern attack speed/density).
Left Side is the easiest of the 4th paths. Right Side is 3rd place, Extreme is 2nd hardest and Extreme+ is the absolute hardest possible setting. For achivements, Right Side and possibly Extreme (Depending on difficulty) may be needed. Extreme+ is just to challenge yourself as far as I know.

[@endless2178]

thanks you for information :)
