What is the theme? It's not Slumber, and it's not Cool either... it's some sort of ugly faded version of both mashed together that just looks ugly with everything

Mechanically speaking it's fine, but aesthetically I can't for the life of me understand why you didn't just keep it Cool themed or make it legit Slumber themed instead of some ugly variant

There's probably some other gear that needs to be looked at in terms of cosmetic compatibility. Mercurial is "technically" Volcanic, but would fare way better with some of it's own chrome themed accessories, and then you have stuff like Mad Bomber which are "Rusty" themed and haven't had any accessories put in their color, meanwhile we've got enough time to make stuff for all of the birthstones and status effects.... not to say I don't like them, I'm just asking for some gaps to be filled before you inject another new color scheme in
