Wizard Lock

Spell School: celestial
Spell Level: 6
Effect Group: Eldritch Force
Spell Incant: With Eldritch force I build a Wizard Lock
Spell Description: This spell is identical to a Ward spell except that it is cancelled by a Dispel. If a room or building already has a Ward or a Wizard Lock, any other one may not be added. If you wish to upgrade your Wizard Lock into a Ward, you must first Dispel the Wizard Lock. In all other respects, this spell follows all of the rules for a Ward, including the use of Lesser Investment. The building must be visibly marked with a large “W” to indicate the presence of a Ward or Wizard Lock. There is no way to tell the difference between a Ward or a Wizard Lock just by looking at it; the only way to tell is to cast a Dispel at the portal and see if it remains. You must have a marshal present in order to do this.
