Epidemic of Flame

Roaring, animated flame appears in your hands and streaks towards a creature of your choice within range. On a successful hit, the fire wraps around the creature, dealing 4d8 fire damage before slithering outwards to another creature within 20 ft. of the first target. The flames continue to spread as long as long as a hostile creatures remain within range and the attack hits. Upon missing a target or running out of targets, the flames dissipate.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the damage increases by 1d8 for each slot level above 6th.
