Unpickable Lock

This spell can be cast on any lock (key or combination) and lasts for 2 to 4 months. Any character attempting to pick the affected lock suffers a -25% penalty to his Open locks score. This spell can be keyed to a single individual (not necessarily the spellcaster) who can open the ensorcelled lock freely, even without the proper key or combination.

The material component of this spell is a sliver of bone.

Notes: Rare spell.
