Armor of Morgana

You surround yourself with a fey-woven ward that lashes at the minds of those who strike you. 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 psychic damage, as the ward inflicts a sudden surge of disorienting mental pain.

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