Rank Question

[SilentStorm2020]

I get the opportunity to level up my rank now in hades bedroom. A ghost is there and you give him what he requires such as 1000 darkness and 1 diamond for example. The requirements change each time but im curious what do you get out of this? Do you get anything for maxing your rank? or is it just a cosmic thing? If its nothing, i rather put my darkness and other stuff in the mirror.

Take what the game told you as literal; it's nothing useful, but something for your ego. So yeah, spend your resources everywhere else but there, unless you REALLY wanna 100% the game.
