Kumawakamaru crazy price for no effect

Hey guys, just a heads up, im playing on mobile. So I have Kumawakamaru on lvl14, and it ONLY has an effect of "-1.05 monsters required to advance to the next level", meaning that it takes me 9 monsters for a new zone. The next level costs 32768 souls, which is absurd, as it will only give me an increase of +- 0.04 less monsters. Shouldnt it only have 5 levels with each of them removing one monster?

Also, I cant find any relics that add to the kumawakamaru level, are there none?
