Undead Summoning IV

Simply a more powerful version of the earlier undead summonings, this spell conjures 2d4 ghasts (40% chance), 2d4 shadows (20% chance), or 2d4 juju zombies (40% chance) to the caster's aid. 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 mummy, vampire, or lich.

Notes: Restricted to necromancers, rare.
