Price 50,000 gp; Slot none; CL 7th; Weight 2 lbs.; Aura moderate abjuration
Forged from adamantine and silver, this heavy lock’s shank is large enough to wrap around a humanoid ankle, magically resizing itself to fit any wearer. When the lock is placed on a creature, it immediately suppresses all magical polymorph effects or supernatural shapechanging effects (such as a lycanthrope’s change shape ability) affecting the wearer, returning her to her true form. The lock of formbinding does not negate these effects, and creatures return to their altered form if the lock is removed before the effect’s duration expires. Creatures targeted by a polymorph effect while wearing a lock of formbinding are affected for only a single round before the lock returns them to their true form.
A creature wearing a lock of formbinding can likewise change its own shape, but it must succeed at a DC 16 Will saving throw at the end of each round or revert to its true form; the lock resizes to accommodate whatever new forms its wearer might temporarily assume.
