Magic Weapon Abilities - Prismatic Burst
A multicolored beam of light plays over the victim of this weapon when its wielder strikes true. On a successful critical hit, the weapon strikes the target with a prismatic spray effect (save DC 20). This effect activates even if the creature struck is not subject to critical hits (roll to see if a critical hit occurs, then apply the prismatic spray effect if appropriate).
