Death Drinker (Su)

Benefit(s): The slayer can renew himself with the energy released when a creature is killed. When the slayer makes an attack that kills a creature with a CR or HD equal to at least half the slayer’s character level, the slayer may heal himself as a swift action. This healing restores 1d8 hit points +1 per slayer level. The slayer may use this ability a number of times per day equal to 1 plus his Intelligence bonus.

A slayer may take this talent more than once, but not more than once per two class levels, to a maximum of taking it five times. Each time it is taken the ability heals an additional 1d8 hit points when used.
