Call Undead

This spell allows a wizard to summon any undead of 6 hit dice or less within spell range, but does not give the caster any control over them. A wizard may use this spell to bring hidden undead out where they can be dealt with by companions or the wizard's own spells, or bring down an undead attack on foes or captors. The call does not allow the undead to unerringly locate the caller.

Lesser undead within range when the spell is cast immediately move at full normal rate towards the caster. Note that this range extends above and below the caster. Greater undead may accompany them, but are not compelled to do so. This spell is effective through water, solid stone, and all non-magical barriers, but is not effective from one plane to another.

This spell may be used to bring back previously turned undead, forcing another turning attempt. Its material component is a piece of bone from any creature.
