DESCRIPTION

This ritual calls a servitor of the Outer Gods at the center of a large ritual circle. The servitor so called will often in turn summon other servitors or eldritch horrors with malign intent to bring forth something beyond the casters’ ability to deal with.

Sometimes, it may be the creature’s goal to parley and offer knowledge to the casters, and at other times its primary desire is to summon a Great Old One or other horrendously destructive entity.

Tomes containing this spell occasionally recommend not casting it under conditions in which it could accidentally summon powerful creatures that can immediately summon other creatures, since the required circle is often sufficiently magically charged and large enough for the servitor to summon nearly any creature it desires after it arrives.

The ritual’s casting time can be shortened to a minimum of 1 hour by sacrificing prepared conjuration spell slots, which reduce the casting time by 1 hour per spell level so used. Spellcasters who cast spells spontaneously can sacrifice available spell slots this way so long as they know a conjuration spell of that level.
