Telepathy (Compulsion) [mind-affecting]
You broadcast a telepathic cacophony calculated to snap the minds of those caught within the area. Affected subjects undergo a psychotic break and begin to attack the nearest creature (for this purpose, a psicrystal doesn't count as a creature). Any psychotic character who is attacked automatically attacks its last attacker on its next turn, as long as the duration continues. A psychotic character will not make attacks of opportunity against any creature that it is not already devoted to attacking (either because of its most recent action or because it has just been attacked).
For every 2 additional power points you spend, the power's save DC increases by 1.
