A wizard lock spell cast upon a door, chest, or portal magically locks it. The caster can freely pass his own lock without affecting it; otherwise, the wizard-locked door or object can be opened only by breaking in, by a successful dispel magic or knock spell, or by a wizard 4 or more levels higher than the one casting the spell. Note that the last 2 methods do not remove the wizard lock; they only negate it for a brief duration – about one turn. Creatures from other planes cannot burst a wizard lock as they can a held portal (see the hold portal spell).
