The ground catches fire when you move leaving a fiery trail behind you. For the duration, your movement creates a small wall of fire in your path. Whenever you move out of a space, that ground in that space catches fire leaving flames in a 5-foot-cube until the beginning of your next turn. This trail of fire does not harm you. Other creatures that enter within 5 feet of one of these cubes for the first time on a turn or ends its turn there must make a Dexterity saving throw or take 2d6 fire damage. A creatures that enter into one of these flames for the first time on a turn or ends its turn there automatically takes 3d6 fire damage.

The fire ignites flammable objects in its area that aren’t being worn or carried, and each 5-foot cube of flames shed bright light in a 20-foot radius and dim light for an additional 20 feet.
