Effect one dimensional shambler
Duration instantaneous
Saving Throw Will negates; Spell Resistance yes


This ritual summons a dimensional shambler, which appears outside the caster’s protective circle. Although it gets a Will saving throw and spell resistance to resist being called, it suffers a penalty to each if the caster has an appropriate tome. It is not under the caster’s control until the bind dimensional shambler ritual is complete, and in the meantime will attempt to attack or abduct any available companions of the caster who are not safe inside protective circles of their own.

The dimensional shambler cannot attack or affect creatures through the barrier of a protective circle for as long as the circle remains unbroken. Shamblers are loathe to depart the place to which they have been summoned without taking a meal along to other planes.
