Summon undead IV

Summon undead IV, also known as undead summoning IV, was one of the series of summon undead spells available to arcane casters in the Realms.

Effects
This spell could summon an allip, a ghast, or a huge zombie, which was usually the remains of a wyvern. As an alternative, the spell could summon one to three ghouls, one to three huge skeletons, one to three large zombies, two to five large or medium-sized skeletons, or two to five medium-sized or small zombies&mdash;provided they were all within 30 feet of each other.

If a ghast or ghoul were summoned, the spell was considered a chaotic spell in addition to an evil one.

History
This spell was known to be used by wizards of the Cult of the Dragon.
