Wizard Lock

A wizard lock spell magically locks a door, gate, similar portal, or any item that has a lock. The magical lock is permanent but may be bypassed as follows:

• The caster can freely pass his or her own wizard lock.
• A knock spell allows passage.
• Any magic-using character who is at least 3 levels higher than the caster of the wizard lock may pass through unimpeded.

Bypassing a wizard lock does not destroy it.
