When cast, the spell causes a cone of invisible, silent, mildly cold force to come into being, extending from the caster's outstretched hand.  Any undead creatures within its confines or touched by any part of it are affected as follows:

Zombies, Skeletons, ghouls, shadows, and such undead with less than 4 Hit Dice are instantly blasted out of existence.

More powerful undead, and creatures from other planes that can by turned by priests can make a Will save to avoid destruction, and if successful instantly suffer 1d6 damage per caster level, to a maximum of 10d6. 

The focus for this spell is a strand of cobweb.
