Celliwig's Desire that Burns

Two points form in the shape of golden slitted eyes, white veins throb as pink flame churns the air around them. You target a creature within range that you can see. Creatures that can't be charmed are immune to this effect. Each target must make a Wisdom saving throw. On a failed save, they take 3d6 as they are lit in a pinkish flame shedding dim light for ten feet. They take 2d6 fire damage at the start of their turns and may use an action to make another Wisdom saving throw, ending the effect on a success.

When a creature under this effect is subjected to a different enchantment spell the recurring fire damage increases by 1d6.
