The guide for Azure Bay is missing a hidden Star Piece and Hyper Potion. One is on the far right side while the other is in the small rock where the DeepSea items are located. TM81 is also found there, but it's not listed.
Small error. Sky Trainer Elata uses a lv28 Fletchinder, not Talonflame.
Not sure if it's been mentioned, but several of the trainers have different pokemon, depending on which version is being played. Twice now I've encountered teams that are slightly different than what the routes have listed.
I'm playing Y and Ace Trainer Mireille (Route 21) has Sableye...
