Shadow Weaver's Guise

This patchwork gray cloak has three bone clasps at its neck. Whenever you cast an evocation spell that deals damage while wearing this cloak, you can choose to change its damage type to necrotic for that casting of the spell.

Curse. Once you don this cursed cloak, you are unwilling to remove it unless you are targeted by the remove curse spell or similar magic. While wearing the cloak, you are considered to be undead whenever you are in dim light or darkness. In addition, if you can normally cast the light or dancing lights cantrips, you are unable to cast them while wearing the cloak.
