An arbiter gains a +4 bonus to recognize and disbelieve illusions created by creatures with the chaotic subtype or possessing the chaotic descriptor.
An arbiter can release electrical energy from its body in a 10-foot-radius burst that deals 3d6 electricity damage (DC 13 Reflex half). Immediately following such a burst, the arbiter becomes stunned for 24 hours. The save DC is Constitution-based.
An arbiter can always sense the direction of the nearest non-arbiter inevitable on the plane, the better to help it report back to its superiors. It cannot sense the range to this inevitable.
