Bailey's Brooch Trap

Bailey's Brooch is a security device that comes in the form of a silver brooch inset with a small red gem.  When placed on an item no larger than 5' in any one dimension and the command word is given, the brooch will adhere to its surface and will activate. Once activated the brooch will be destroyed dealing 2d10 force damage to any creature when it tries to wield, hold, open, wear or otherwise manipulate the item Bailey's Brooch is protecting. Casually touching the item will not set off the brooch's damage., Speaking the command word again will deactivate it and cause it to unstick from the item it was placed on.

Notes: Damage, Warding
