Undead Summoning V

This spell resembles monster summoning V, except that it conjures 3d4 ghasts (40% chance), 2d3 giant skeletons (40% chance), or 1d3+1 banshees (20% 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.
