Icewind Dale Wiki

Casting this spell opens a channel between the caster's plane and the Negative Energy Plane. The caster acts as a conduit between the two planes, sucking life from a victim and transferring it to the Negative Energy Plane, draining them of 2 levels of experience. The target of this spell loses levels, Hit Dice, Hit Points, and abilities permanently. These levels can only be stored by a priest's Restoration spell. This spell has no effect on undead, constructs, or extraplanar creatures.
