@Dusksong Showdown is totally unnecessary for it unless you really want to use it. You can flat out say you trained and take a level for it if that's easy for you. Major battles (gym battles, admin battles, etc.) account for 2 levels.
@Dusksong Yeah, you can level up from wild battles or make up a trainer battle, though Heckno or I can create a random NPC for you to fight if you want.
@LuckyBlackCat As soon as the business with Hammer's finished, Rheese is going to get his Minior. I've been trodding along with two for a bit too long.
