Death Vortex

Death Vortex is a very strong attack spell.

Spell Description
This spells creates a swirling, black vortex of death - it literally drains away a creature's life energy. First the vortex will move to the point designated by the mage; if an enemy was targeted, the vortex will follow them until it is killed. Then it will move on to new targets. However, the vortex is totally harmless to the caster and their party. Thus, casting it on oneself will create a zone of death around the caster without any side-effects.

Energy Mist is a lesser version of this spell.
