Aura of Solaris

Softly glowing flames surround you and your gear, shedding dim light in 30 ft. radius, ready to violently flare in your defense. You gain 5 temp hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the creature takes 5 fire damage.

At Higher Levels. Casting this spell with a spell slot 2nd level or higher, both the temporary hit points and the fire damage increase by 5 for each slot.
