Widowgast's Web of Fire (2)

Striking both palms down upon the ground, a web of flame crackles out around the caster and five streaks of fire rapidly snake along the ground towards up to five enemies the caster can see within a range of 60ft, leaping towards their target and exploding into a column of fire upon reaching them. Each target must make a Dexterity saving throw, taking 8d6 fire damage on a failed save, or half as much damage on a successful one.

Alternatively, all five streaks of fire can instead converge towards a single target, dealing 12d6 fire damage on a failed save, or half as much on a successful one.

the fire can travel over obstacles up to 5 feet high, and ignite flammable objects along its path that aren't being worn or carried.
