Okay, Ruby's back on track now. Everyone's in the level 21-25 range, and everyone's got at least one decent damage-inflicting STAB attack. Now I can do some serious training.
Outside Meteor Falls right now. Poked my nose into Team Magma's business and freed Professor Cozmo from their clutches. Now I've just got to pump everyone up a bit for when I go to Mt. Chimney. Maxie's Camerupt will be easy for Marshtomp to take care of, but I want to have some slightly stronger reserves to handle everything else.
