I'm partly high right now but hear me out, what if for like 80-100 eps, you could buy a spirit animal skill from Ep shop, the skill can summon an that can Animal can follow you around and either give you a boost, attack along side you, or nerf an enemy, ect.
Ex.
Spirit of Dog
Cost: 95% of Rei
CoolDown: 120 mins
Dog
Health: 20k-100k (depending on owner's level)
Rei: 1k-10k (Depending on owner's level)
Atk: .3 of owner's overall attack
Def: .4 - .5 of owner's overall def
Reiatsu: .3 of owner's overall attack (there is no need for this but just including, dog shouldn't be able to use skills anyway)
Ability: When summoned Dog can follow you around and attack enemies that you attack/target
