Compared to the other rifts, the creeper king does barely any damage. In the other fights, I'd have to fix my armor several times and run away because of the damage. Creeper didn't even do 1/3 of damage to my armor and I never went below 20 health. This would be fine but it gives the same prize as the others, 10 War Keys. I would suggest to either nerf the prize or buff the boss or buff the other prizes.
