Black Flame

A burst of black flames erupts in a loud sizzle and flickers towards a target in range.
Make a ranged spell attack if the target is a creature.

The target takes 2d12 fire damage, 2d12 cold damage and 2d12 necrotic damage.
If there were any light sources (including magical) within 30 feet of the target, they get extinguished.
Black Flame can neither freeze things nor light them on fire.

When cast with a 6th level spell slot or higher, the damage per type increases by 1d6 for each spell slot level above fifth.
So at for example 8th level, this spell deals 2d12 + 3d6 fire, cold and necrotic damage each.
