2nd-level conjuration
Casting Time: 1 action
Range: 20 meters
Components: V, S, M (a bit of tallow, a pinch of brimstone, and a dusting of powdered iron)
Duration: Concentration, up to 1 minute
A 1-meter-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 1 meter of the sphere must make a Dexterity 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, you can move the sphere up to 10 meters. 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.
When you move the sphere, you can direct it over barriers up to 2 meters tall and jump it across pits up to 4 meters wide. The sphere ignites flammable objects not being worn or carried, and it sheds bright light in a 6-meter radius and dim light for an additional 6 meters.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd. When you cast this spell using a spell slot of 4th level or higher, the diameter of the sphere increases by 1 meter for each two slot levels above 2nd.
