Deathly Diadem

Alter: This gruesome crown was worn by a powerful lich before falling into the hands of the adventurers who slayed it. While wearing the crown, you have resistance to necrotic damage, are always under the effect of the tongues spell, and you can cast speak with dead at will. When you cast speak with dead in this way, you can only ask th target one question, to which the target answers with either yes, no or maybe. If the question can't be answered in this way, the spell ends. In addition, while you wear this crown, undead creatures have disadvantage on attack rolls against you.

Attunement: Yes, cursed
Curse: This crown is cursed, a fact that is only revealed to you when you die. The first time that you die while attuned to this crown, its curse is extended to you, and you are immediately returned to life with one hit point. While cursed, your alignment becomes evil, if it isn't already, and your utmost goal is to become an all powerful lich. While cursed, your creature type becomes undead, in addition to your other existing creature types.

A creature remains cursed in this way until targeted by a wish spell or divine intervention. removing the crown fails to end the curse. While a cursed creature may not reveal that the diadem is cursed, its allies may be able to deduce its presence and effects based on the creature's behavior.
