This brooch is little more than a hunk of gray rock studded with a number of colorful, uncut gems and wrapped in tarnished metal wire.

While wearing this item, you gain darkvision out to 30 feet and a +5 competence bonus on Hide checks. These are continuous effects and require no activation.
Once per day, you can activate the badge to give yourself a blur effect (as the spell).

Prerequisites: Craft Wondrous Item, blur, darkvision, svirfneblin.
Cost to Create: 7,500 gp, 600 XP, 15 days.
