You summon a bit of greenish fire to the top of your head, into one hand, or at the tip of your tail. It flares brightly, and all creatures that see your soul fire must make a Wisdom saving throw. On a failed save, the creature becomes charmed for the duration. While charmed by this spell, the creature seeks to follow the light, even into areas of bright light or darkness or into shallow water. The spell ends for an affected creature if it takes any damage or if someone else uses an action to shake the creature out of its stupor.
