Chaos Strike

You hurl an undulating, warbling mass of chaotic energy at one creature in range. Make a ranged spell attack against the target. On a hit, the target takes 3d10 + 2d4 damage. Choose one of the d10s. The number rolled on that die determines the attack’s damage type, as shown below.

If you roll a 4 on either of the d4s, the strike deals 2d6 extra damage to the target. If you roll a 6 on either of the d6s, the strike deals 2d8 extra damage to the target. If you roll an 8 on either of the d8s, the strike deals an extra 2d10 extra damage to the target. If you then troll a 10 on either of the additional d10s, the strike deals 2d12 extra damage to that target. If you roll a 12 on either of the d12s, the strike deals an additional 2d20 extra damage to the target. If then roll a 20 on either of the d20s, the strike deals 1d100 extra damage to the target.
