Chaos Blast

You hurl an undulating, warbling beam of chaotic energy at one target within range. Make a ranged spell attack against the target. On a hit, the target takes 1d8 damage. Choose one of the d8s. The number rolled on that die determines the attack’s damage type, as shown below.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
