I chose South and arrived in Memorenia. I found all the Minube and now I just need the rainbow. My strategy is crossing the map from Area 17 to Area 06, then when i arrive in Area 16/06 i rest to the fountain till morning. This triggered rain in Area 01 so it affects weather for sure. Is there a better way at this point of the game to trigger the rainbow? Or is this the best i can try?
