Red eye of the being who inhabits your body. It allows you to leverage some of his hellistic, celestial nature. While in place, you are unable to unattune from this item as it replaces one of your own eyes. While attuned, you are able to read any language which Abaddon would be able to read as his mind is melded with yours. Additionally, once per rest, you may use the attack action to cast the spell guiding bolt except the damage done is necrotic in place of radiant. If you have the ability to do more than one attack, this only counts as one of those attacks.

Notes: Language: All, You and Abaddon must be bound together.
