Edge of the Empire

This strange, emerald disk is covered in glowing runes. When presented strongly to one or more undead creatures within 45 feet as a standard action, each must succeed at a DC 13 Will save or be unable to attack the wielder or the wielder's apparent allies for as long as the wielder continues to present it as a move action each round. Any undead that succeeds on this saving throw or that is attacked by a protected creature is immune to that disk of the Hyades for 1 day.
