|Components:||V, S, M|
|Casting Time:||1 standard action|
|Target:||The door, chest, or portal touched, up to 30 sq. ft./level in size|
An arcane lock spell cast upon a door, chest, or portal magically locks it. You can freely pass your own arcane lock without affecting it; otherwise, a door or object secured with this spell can be opened only by breaking in or with a successful dispel magic or knock spell. Add 10 to the normal DC to break open a door or portal affected by this spell. (A knock spell does not remove an arcane lock; it only suppresses the effect for 10 minutes.)
Gold dust worth 25 gp.
