You curl up into a ball and roll super fast in any direction. You're able to turn while doing this, and you can pass through occupied spaces. When you do, the creature in that space takes 1d8 force damage as you hit them. Range for this is your walking speed plus 3 times your DEX modifier. The damage increases by 1d8 at level 5 (2d8), 10 (3d8), 15 (4d8), and 20 (5d8).

You jump up and lock on to the nearest enemy. Make a melee attack roll. If it hits, you do 2d6 force damage. Otherwise, you land in a unoccupied space next to them. The damage goes up by 1d6 at level 7 (3d6), 16 (4d6), and 20 (5d6).

At level 10, you unlock the ability to go into a different form called a super form. This form makes you turn yellow and you give off bright light for 15 feet, and dim light for 15 feet. You can go into your super form a amount of times equal to 3 + your proficiency bonus. In this form, you deal double damage with your weapon (including your proficiency bonus), you can make 3 extra weapon attacks  (not including extra attacks from class levels), and you gain a flying speed equal to your walking speed times 2.
