Blood Infusion (3.5e Feat)
From D&D Wiki
 Blood Infusion [General]
You may heal others with your blood.
Prerequisite: Staunch class ability
Benefit: You can now heal others wounds with your blood. You must take a full round action to slice your veins and those of your recipient, letting your blood travel into their body. You may subtract any number of hit points from your own, healing your recipient of the same amount.
Special: For every 5 hit points you give up, you are dealt 1 point of Constitution damage. For every 1 point of Constitution damage you take, your recipient is healed an equal amount.
