The Pet System
page has been created.
It could use some information about pet satiety and energy drinks, and there are probably a few things that could be clarified like when exactly a pet gains xp: When it's summoned, in storage or some sort of training mode? Is xp gain affected by satiety? Google translate on the official page is typically confusing on these points.
I thought it best to split the cash shop aspect into it's own page (which does not yet exist) and mounts/bikes is too small a topic to need more then one page.
Also reshuffled the main page's Game Basics, Systems and Mechanics categories a little, since it was a bit of a mess. I'm aware it was based on the KR website, but that site is a bit cludgy and dated.
I got a bit lazy about adding things to the wiki in the last week or so, so if there's any good info I missed feel free to link it.
