Undead Summoning II

An improvement of the 3rd-level spell undead summoning I, this spell resembles its weaker relation, except that undead summoning II conjures 2d4 zombies (75% chance) or 2d3 heucuvas (25% chance). The monsters attack the caster's enemies to the best of their ability until he commands the attack to cease, the spell duration expires, or the monsters are defeated or turned. The undead summoned by this spell vanish when slain. If no enemy is present for the undead to engage, they follow any other commands or undertake simple tasks as the wizard directs.

The material component is a bit of bone taken from a wight, ghast, or mummy.

Notes: Restricted to necromancers; rare.
