Lensing Palm (3.5e Martial Artist Maneuver)
From D&D Wiki
Some creatures are too tough for their own good.
Level: Tempered 1
Type: Action (Attack)
Description: During the round in which this maneuver is used, if the damage you deal with your unarmed attacks is reduced by an opponent's damage reduction, that opponent is dealt damage at the start of its turn equal to the total points of damage its damage reduction absorbed from your attacks. A successful Fortitude save against a DC of 10 + ½ your initiator level + your Intelligence modifier halves this damage.
Special: This maneuver may be initiated as a swift action. Its effects apply to all unarmed strikes you make during your turn.
