Chaotic Flame

You blast a cone of fire from your hands that extends 30ft in front of you. Creatures caught within the cone must make a Dexterity saving throw or 3d8 fire damage and 3d6 damage of other kinds. To determine the other damage types, roll a d4. The number rolled on that die determines the attack’s damage type, as shown below. Each d6 requires a separate roll, and does different damage types respectfully.

You cannot change the rolled damage types in any way.

At Higher Levels. When you cast this spell using a spell slot of 4nd level or higher, each target takes 1d6 extra damage of the type rolled for each slot level above 3rd.
