  You draw forth the ebbing life force of all nearby badly wounded creatures and use it to fuel your own power.

  Upon casting this spell, you radiate a consumptive death field.

  All creatures in the area with fewer than 0 hit points that fail their saving throws die, and you may add 1 temporary essence point per death caused by this spell. Creatures that fall to -1 hit points or lower in the area after the spell is cast are likewise subject to its effect. No creature can be affected by this spell more than once per casting, regardless of the number of times that the area of the spell passes over them.
  Whenever you cast another spell while this spell lasts, you may expend 1 or more essence points as an additional component to increase the caster level of that spell by the same amount. Doing so adds the evil descriptor to that spell.

  Once this spell expires, all unspent essence points gained from it are lost.
