Chaos Stike

You hurl an undulating, warbling mass of chaotic energy at one creature in range. Make a ranged spell attack against the target. Or you can choose to make a 10 foot range melee spell attack instead. Regardless of the range/melee type, on a hit, the target takes 1d8+Spellcasting Mod damage. The number rolled on that die determines the attack’s damage type, as shown below.

At Higher Levels. When you are at higher Ranks you roll more d8s and you can choose between the values of what damage type to use. 2d8 at Rank 2, 3d8 at Rank 3, and 4d8 at Rank 4.
