Retribution

Type: General
Source: Dragon #326

Taking damage drives you to greater heights of combat prowess.
Prerequisite: Power Attack.
Benefit: For every 5 points of damage you take from a single creature in one round, you gain a cumulative +1 bonus on damage rolls against that target on your next attack. For example, a monster deals 13 points of damage to a fighter with this feat in one round; in the next round the fighter successfully hits the monster and deals +2 additional points of damage against that monster. If the fighter gets multiple attacks in a round, the bonus damage only counts for the first attack (and only if that attack hits).
Bonus damage provided by this feat does not stack from round to round and only applies to your next attack. If you gain bonus damage from Retribution but you miss your target, you also lose the bonus damage provided by this feat. This feat's bonus damage only applies against the creature that dealt you damage, whether from melee or ranged attacks, spells, special attacks, or any other form. The bonus damage cannot be used to deal extra damage to creatures other than your attacker. In the case of attacks where you cannot conclusively discern from whom or what the attack came, you gain no bonus damage.
