Feat: Living Anatomy (3.x or others)

[J-H]

Yes, this is a take-off from Fallout 2.

Requirements: 10 skill ranks in Heal.

Any attack made by the character against a creature whose species he has healed at least 3 members of gets an insight bonus of +1 to-hit and +2 to damage.

Very good idea, seems a bit overpowered in its current incarnation, but I don't know what level to set it at to get it to work... even +1 damage might be OK given that it is so open ended.

I wouldn't let just stablizing someone or treating a caltrop wound count... countering poison maybe, and definitely long-term care should count.
