Chaos Blast

You unleash a beam of chaoticenergy at one creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 damage of a type you choose: Acid, Cold, Fire, Lightning, Poison, Psychic, or Thunder.

If you roll an 8 on a d8 for this spell, you can roll another d8, and add it to the damage. When you cast this spell, the maximum number of these d8s you can add to the spell’s damage equals your spellcasting ability modifier.

The spell creates more than one beam when you reach higher levels: two beams at 5th level, three beams at 11th level, and four beams at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.
