How about a way to take down armor as a monk in Pathfinder?
Crack the Shell (Combat)
Prerequisites: Improved Unarmed Strike, Ki pool class feature, Wis 13
Benefit: You learn how to channel your ki into the armor of another to devastating effect. When you make an unarmed strike, you may declare you are using this feat and may spend up to 1 ki point per three character levels. If you successfully strike the target and the target takes damage from the blow and the creature must attempt a Fortitude saving throw (DC 10 + 1/2 the character’s level + the character’s Wis modifier). On a failure the armor takes damage equal 5 times the ki points spent. If the saving throw is successful, the target’s armor is unaffected. Creatures with natural armor have the bonus from their natural armor reduced by the number of ki points, up to to the natural armor bonus. After a week of natural rest or healing magic the natural armor bonus returns. If the target as multiple armor bonuses from natural and artificial armor, you may choose which one to attack.
