Darkfire Spear Imitation

You launch a bar of black and red fire at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d12 equal parts fire and force damage. A flammable object hit by this spell ignites if it isn't being worn or carried. If you hit your first attack with this cantrip you can redirect the beam to a number of other targets equal to your proficiency bonus. You cannot attack the same creature twice.

This spell's damage increases by 1d12 when you reach 5th level (2d12), 11th level (3d12), and 17th level (4d12).
