Again, judge about how strong your character should be... for example, after a dungeon, or so, a snivy that didn't start with the move, would learn Vine Whip.... also, move training is a thing in this RP, basically, the more you use them, the stronger moves are here, however, Kabling can't be stuffed keeping track of that, so you'll have to kind of do that, or don't, and just assume that a move that your character uses often will be at about the right strength for whatever you need at the time.
