Avatar State

The power of your ancestors flows through your veins as you go into the avatar state. In this state, you gain the powers of the four elements. Roll a d4 to see what elemental attack you can make. 1: water; 2: earth; 3: fire; 4: Air. On a hit, the target takes 1d10 damage. Hit or miss, the elemental explodes. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d6 elemental damage.

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