Duration: Concentration, up to 1 minute
The next time you hit a creature with an elemental attack during this form's duration, your fire flares with white-hot intensity, and the attack deals an extra 2d10 fire damage to the target and causes the target to ignite in flames. At the start of its turns, until the form ends, the target must make a Constitution saving throw. On a failed save, it takes 1d10 fire damage. On a successful save, the form ends. If the target or a creature within 5 feet of it uses an action to put out the flames, or if some other effect douses the flames (such as the target being submerged in water, the form ends.
At Higher Levels. When you initiate this form at a higher level, the damage increases by 1d10 for each level above 2nd.
