So, I picked up Silver version just for the lulz, and I decided on this run I would try raising an Umbreon (I've never had the patience before.)
I was checking the Happiness guide, and I have a stupid question:
-Usage in Important Battle [Gym Leaders, Elites, Red] (+3 0-199, +2 200-249)
Do I have to actually win the battle? Or can I deliberately lose and deal with the -1 loss from fainting and gain +2 in about a minute and a half? Over and over and over again...
