Fiend Circlet

A fiend circlet is only given to a spellcaster who has made a formal pact of service to a baatezu lord (one of the Dark Eight), and are therefore very rare indeed. The wearer gains a +2 bonus to AC (if not wearing metal armor), and the resistances to attack forms and magical alignment change as per fiend armor. The following powers each can be cast from a fiend circlet, three times a week:

advanced illusion, animate dead, charm person, infravision, know alignment, suggestion.
