Black Armor

Cloak yourself in otherworldly armor. This armor does not require you to remove any armor you are currently wearing, and does not count as armor. While this armor is being worn you gain the following benefits.

• Add your Charisma modifier to your AC.
• Your attacks count as magical for the sake of ignoring armor
• Your melee attacks deal an extra 1d8 necrotic damage

At higher levels: You gain your Charisma modifier modifier to you in temporary hit points when you defeat a creature while wearing this armor, when you cast this spell with a 4th level spell slot or higher. Your damage increases an extra 1d8 per spell slot above 3rd level.
