Open Ground

Open Ground was originally meant as a tool to help in the Necromancer's primary task of burying the dead. Casting it near a tombstone will open the ground, thus allowing the caster to put a body into the newly created grave. However, it is more potent than this and can be used to open up rock walls and other earth-based obstacles that block the path of the Necromancer.

A very versatile tool in the right hands.
