The character draws forth the ebbing life force of a badly
wounded creature and use it to fuel the character's own power.
Upon casting this spell, the character touches a living creature
with 1 hit points or lower. If the subject fails its saving
throw, it dies, and the character gains 1d8 temporary hit points
and +2 Strength. Additionally, the character's effective caster
level goes up by +1, improving spell effects dependent on caster
level. (This increase in effective caster level does not grant
the character access to more spells.) These effects last for 10
minutes per HD of the target creature.
