Armor of Orcus

You surround yourself with the clinging essence of undeath — a chilling aura of necrotic decay that seeps from your flesh like spectral rot. Wisps of black mist coil around you, carrying the faint sound of whispers from beyond the grave.

You gain 5 temporary hit points for the spell’s duration. While you have these hit points, any creature that hits you with a melee attack takes 5 necrotic damage as your aura of death lashes out, leeching life and vitality.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both the temporary hit points and the necrotic damage increase by 5 for each slot level above 1st.
