Meeki said:Why don't you make it work only when the target is flat footed (or denied its dex bonus to AC I suppose, but that is more common than flatfooted) so it can't be used every round against a flanked foe. Would definitely limit its use.
maybe but whats the logic behind that? (yes i know i put down the "logic" argument before) just trying to understand what would let you use it on someone flatfooted but not on someone flanked.
any comments on my idea to attach a skill check for knowledge:anatomy instead of a save?
