Whenever you deal damage directed at an ally, that ally’s attack roll is increased by the level of damage dealt. The damage dealt also has a bonus of the amount of damage that was dealt to your ally. For example, if you dealt 15 points of damage to an ally, that ally would get a +15 to any roll for that turn, as well as a +15 to damage that would go against another target.

This Feat can not be stacked.
