Initiation Time: 1 bonus action
Range: 60 feet
Duration: Concentration, up to 1 minute
A 5-foot-diameter sphere of fire appears in an unoccupied space of your choice within range and lasts for the duration. Any creature that ends its turn within 5 feet of the sphere must make a Constitution saving throw. The creature takes 2d6 fire damage on a failed save, or half as much damage on a successful one.
As a bonus action, on your turn, you can move the sphere up to 30 feet within range. If you ram the sphere into a creature, that creature must make the saving throw against the sphere's damage, and the sphere stops moving this turn. The sphere ignites flammable objects not being worn or carried, and it sheds bright light in a 20-foot radius and dim light for an additional 20 feet.
At Higher Levels. When you initiate this form at a higher level, the damage increases by 1d6 for each level above 2nd.
