Gray Rift

Calling upon the negative energy of the Gray to bolster the unliving, you conjure a two–dimensional diamond–shaped rift.

An overwhelming stench of decay assaults your nose, confirming the connection to the plane of the dead. This spell tears and holds open a rift between Athas and the Gray. The rift itself is a two–dimensional, diamond–shaped plane 30 feet high and 15 feet wide in the middle. Any creature that touches the rift is affected as if you cast harm on it. A character that attempts to dispel the rift and fails is also subjected to harm. Once per round as a move action, you can move the rift 30 feet in any direction within range. If you cease concentration or are slain, the rift lingers for 1d6 rounds without moving and then dissipates.

All undead creatures within range gain a +4 profane bonus to Strength, 3 bonus hit points per hit die, and fast healing 1.
