In case anyone is confused why the Mage Slayer plot decays as it does, it's because you only use it when failing - so there's a % chance it's still available after every save. Anyway, I agree. This feat goes on any build that can afford the feat, and pretty much on any martial.
i disagree with your use of the word "improved" in the 2014 version you could make an opportunity attack against an enemy who casts a spell within 5 feet of you, and when you damage an enemy they have disadvantage on concentration checks, also if an enemy is hit while casting they have to make a concentration check to keep casting. the 2014 version was a martial's counterspell with unlimited use. the only thing was, you had to get up in their grill, and it had a 5 foot limit instead of a limit of your reach, so you couldn't benefit from, say, a whip. basically in the 2014 version if you were up close with a caster and they started casting you could just go "no" and smack them and make them stop.
@@tuseroni6085 remember that you have to let the triggering action resolve before your reaction goes off (same as with sentinel). So 2014 mageslayer doesn’t actually prevent the casting of the spell. In order to get the reaction attack from 2014 mageslayer, you have to survive the spell. For example, if hold person was cast, you need to pass the save (with advantage) in order to get the attack. If you fail, you’re paralyzed and can’t make the attack anyways. The relevant reaction timing text (from XGE): “If you’re unsure when a reaction occurs in relation to its trigger, here’s the rule: the reaction happens after its trigger completes, unless the description of the reaction explicitly says otherwise.”
@@zSavageWolves i don't think that is in the PHB, might be XGE nerfed the feat, but i think most people would consider the reaction as happening when they start casting the spell, not when they complete it.
@@tuseroni6085 You're wrong, reread the Mage Slayer feat. It does not have any mechanism for interrupting the casting of the spell. Even if your action resolves during the casting of the spell, a caster who is in the middle of casting a spell is not concentrating on it, otherwise every time a caster uses an instantaneous spell while concentrating on another spell their concentration would break and end the spell lol. You basically invented a rule that doesn't exist (casters are considered to be concentrating in the middle of casting a spell) to try to make a bad feat look better. There is no rule that stats that if you are struck in the middle of casting a spell you have to make a concentration check to complete the spell. It is when you HOLD YOUR ACTION to cast a spell you are considered to be concentrating on it.
@@floofzykitty5072 hm, you may be right, i think i may have been thinking about spells with a casting time longer than 1 action where that is the case and abstracted it to all castings, either that or i got mixed up from another version.
Very strong

@@UKHXC yep, that’s the exact reason! As you get to larger numbers of saves, it approaches save chance * number of saves + 1.
My favorite feet in 2024. Warcaster is second.
