Armor of Morvane

You surround yourself with a ward of withering necrotic energy. For the duration, you gain 5 temporary hit points.

While you have these temporary hit points, any creature that hits you with a melee attack takes 5 necrotic damage, as the ward siphons vitality from those who strike you.

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.
