This is identical to Arcane Lock, except as detailed here. If the door or portal does not have a lock, this spell creates a good lock (DC 30). If it does already have a lock, it provides a enchantment bonus to the lock's DC of +10. Whomever is holding the associated platinum key can freely open an Arcane Seal, not just the caster, and if the Arcane Seal is breached, dispelled or suppressed, a mental alert is immediately triggered to whomever has the platinum key, so long as they are on the same plane. Detecting the presence of an Arcane Seal requires the ability to detect magic and a successful Spellcraft check, DC 20 + caster level. A platinum key used in this spell cannot be associated with more than one active Arcane Seal at a time. The second casting disassociates it from the first.
