From publisher blurb:
So your character has just attacked and BAM; Natural 20! You score a critical threat! You follow up the roll and confirm the critical, adding X2 damage to the…WAIT, You don’t want to do that, not when you can have your cleric deliver a savage blow with his war hammer, breaking the infidel’s sword arm in the process!
Hold on just a second.
Breaking his arm? What’s that you say? You can’t do that…
With Critical Feats now you can!
Critical Feats is a selection of 40 new feats designed to add spice to the critical hit mechanic. No longer do you have to simply take the same old damage over and over again each time you score a critical hit. Now, a critical hit can knock your opponent out, slash his throat, break a limb or even rupture a lung!
Ladies and gentlemen, combat just got more dangerous.
