This spell was originally taught only to the members of the Conclave of
Aldevan, a secret sect within the Invokers of Malkah, but it was revealed in
all its glory when the Conclave used it to drive away the dissidents who had
been corrupted by the twisted arts. The spell creates a nexus of psionic
energies that will keep striking the enemies of the caster as long as the
spell is held. The devastating power of the spell can further be raised if
more than one allied Invokers are casting it simultaneously.
