Description: The caster summons a planar ally. The creature summoned by the caster will be under the rules of the custom summons system of Neversummer 4, described in the Summons Guide. Good casters will summon a Hound Archon, neutral casters will summon a Green Slaad, and evil casters will summon a Succubus.

Note: If of good alignment, and given the choice between this spell and Summon Creature VI; it has +2 ac, -2ab, but double the spell resistance (~35), and the saves are about +4 stronger on this spell. However; the summon creature spell gets over double the damage in comparison.
