This set of picks, pins, and levers is housed in a supple leather bag decorated with arcane runes.

This set of masterwork thieves’ tools is the perfect accessory if you depend on a blend of magic and skill to achieve your thieving goals. In addition to granting the normal +2 circumstance bonus on Disable Device and Open Lock checks, these tools can grant a character with the trapfinding class feature a special benefit.
When activating the tools, you can expend an arcane spell or arcane spell slot of 1st level or higher to gain a +5 competence bonus on either a Disable Device check or an Open Lock check begun before the end of that turn.

Prerequisites: Craft Wondrous Item, knock, trapfinding.
Cost to Create: 500 gp (plus 400 gp for base item), 40 XP, 1 day.
