You draw forth the ebbing life force of a creature and use it to fuel your own power. Upon casting this spell, you touch a living creature that has -1 or fewer
hit points. If the subject fails its
saving throw, it dies, and you gain 1d8
temporary hit points and a +2 bonus to Strength. Additionally, your effective
caster level goes up by +1, improving spell effects dependent on
caster level. (This increase in effective
caster level does not grant you access to more spells.) These effects last for 10 minutes per HD of the subject creature.
