>>58458106I posted in the Lets Play thread but I'm going for Shiny Larvitar on the Wild Area 15 roof. Right now I'm running in, checking if the Larvitars are shiny (or even there), and then running across the rooftops until I hit the one with a ton of Mega Energy crystals, then running back and repeating the cycle. I think this is the best way I can be doing this.
How feasable is the Beldum hunt? At first I was planning to try for Skrelp or Noibat, but I don't think exiting and re-entering the sewers guarentees a reroll for spawns. At least, mons that I knocked out stayed knocked out.
