Hyperborea: The Helmet of Nabu

 

"The Helmet of Fate was created by the Lord of Order Nabu along with two other mystical items: the Amulet of Anubis and the Cloak of Destiny."

Helmet of Nabu: Only a Lawful character can wear the helm and while wearing it they gain an AC of 5, their Hit Points increase by 20,  they can speak, read, and understand any language, gain a +2 to all saving throws, and may cast the following spells: charm person 1/day, detect magic 3/day, dispel magic 1/day, fly 2/day, light at will, lightning bolt 1/ day, magic missile 3/day, protection from evil 1/day, shield 1/day, and teleport 1/day. If a Neutral character attempts to wear the helm they must make a Sorcery saving throw and take 2d8 damage on a failed save or 1/2 of that on a successful save. If a Chaotic character attempts it they must make a Sorcery saving throw at a -2 penalty and take 4d8 damage on a failed save or 1/2 of that on a successful one.
