Hey ab, following up my Smogon pm...I'm about to finish route 10 and I'm falling out of love with Carracosta...the .txt file says that Rayquaza can be found at the Dragonspiral entrance. Haven't seen one in like 300 encounters, which flies in the face of "4%". Did you make this a post-E4 thing (considering almost every other uber/ledge can't even be accessed until then), or maybe forget to put it in your Pitch Black rom, or am I just that unlucky?
