Like in final fantasy you can get new armor, but it doesn't show up on your character, but does in games like diablo.
I tried searching for it under every name I could think of. Nothing. Should probably be in there. Should probably call it 'Visible Equipment Changes' or something simple. I am usually not a fan of weird names for stuff as I think it kind of defeats the purpose of having an easily searchable wiki if you can't easily search the wiki.
