Will-o'-Wisp

You conjure a fiery wisp and sends it flying towards an object or creature. Make a ranged spell attack against the target. On a hit, the target takes 1d8 fire damage. The wisp then attaches itself to the target and sheds bright light over 15 ft. and dim light for another 15 ft.. The wisp fades at the start of your next turn, or if a creature uses an action to brush it off.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
