Elder-Basilisk said:I agree with the majority of the comments here.
Irresistable Phantasmal Killer, Slay Living, Charm Person, Dominate Person, Suggestion, Blindness (as a 6th level spell no less), etc are too good for their level. In fact, they're probably too good for a non-epic game.
Irresistable Zone of Truth and Irresistable Detect Thoughts (both sixth level and therefore available far before Mind Blank which protects against them) would also be potential game-breakers if the game were more politically focussed.
Like many of the feats in the Kalamar book, Irresistable spell is overpowered and probably unsuitable for most campaigns.
Beowulf said:How about Irresistable Daze? Keep the enemy incapacitated the whole fight while the fighter easily chews it apart and the cleric takes a nap.
All for a couple of 5th level spells.
Cheiromancer said:I haven't heard a whole lot of discussion of the KoK books. Can you name some of the overpowered feats that appear there?
As for Irresistable, I agree with the consensus- +4 is way too low. Even +6 is probably not enough.

Daze has a HD limit. Not exactly the best spell to use at higher levels.
