An eagle claw worked from adamantine dangles from a silver chain.

The wearer of an eagle claw talisman is capable of delivering ruinous strikes against doors, locked chests, or other objects. When you activate an eagle claw talisman, you gain a +5 competence bonus on the next Strength check (or unarmed strike damage roll) you make to break or burst an item. This effect lasts for 1 round or until used.
This ability functions three times per day.
