Due to your willpower to be the strongest, your body has gained the ability to grow and improve faster than any other.

You gain 2X experience from levels 1-6, 1.5X from 7-10, 1.25X from 11-15, and 1.125X from levels 16-20.

At fifth level once per long rest you can copy the fighting style of one enemy that you have fought and killed. You gain one attack from their stat block until you take your next long rest. You can hold up to 3 attacks at once, and any attempts to hold more than that will result in the attack that has been used the least being replaced with the new one.
