Amulet of good and evil

In knowledge and in justice my Oath has been broken and found

By the power of my god, I can call upon the spirits of Anubis to give aid or cast confusion with the wisdom of Thoth. As an action, by clutching the amulet in the palm of your hand, you are able to cast one of the following: confusion or spirit shroud

Once per round you can either deal 1d6 of your choice of necrotic or radiant damage on the first melee weapon attack you hit with.

Notes: Damage: Melee Weapon Attacks, Bonus: Initiative, Giving an Oath or Belief, Necklace
