Aura of Heroism

A golden aura spills out from you in a 10ft radius. Creatures you choose that begin their turn within the aura are immune to being frightened and gain temporary hit points equal to your spellcasting ability modifier at the start of each of their turns they remain in the aura. If a creature moves out of the aura they remain immune to being frightened but lose any temporary hit points gained from this spell. When the spell ends, all remaining temporary hit points gained from this spell are lost.
