well i recently start playing the game 2 monts ago and on my adventure discover a cheese for making infinite money since the intended challenge the game presents you its a diferent one, keep in mind that you cant and i repeat YOU CANT WASTE ANY VALUE ITEMS LIEKE REVIVE, it will be a waste using them also this is my first post i didnt know where to put it so i just put it here, now how does it work and where does the action happens? well nearly close to the end so i dont spoiler you anything, when you get to titania house for the second time after you came up the waterfall and you are given the HM02 fly, the tema meteor as always will figth you for the keys and you will have to batlle 3 consecutive times, the first time is with 2 meteors staff members, the second time is with fern and blake, the third time is with solaris and a meteor member, you want to only win the first and the second battle sice they will give you a total of 68,000+ money and if you lose you will only will lose at least 16,000+ you can repeat this as many times you want, it will also give tons of xp for your low lvl pokemons if you want to evolve some and give them some good evs, have fun and enjoy.
my inglish is not to goo when is about writing so i apologyse if anything is wasnt correctly wroted in this post.
