Description: This set of picks count as masterwork theives' tools. In addition, they also automatically glow when within 5 feet of a Hidden Ward effect, thus negating the increase to Perception check DCs provided by that spell. Mostly importantly, however, if used to disable a magical or psionic ward or trap, any telepathic or audible alert that would normally activate does not go off until 10 minutes after the triggering event. Arcane Keys are almost always seen as incredibly illegal.
Construction Requirements: Craft Wondrous Item, Arcane Seal, Hidden Ward
Construction Cost: 900 gp
