Part 2
For the next part, you'll need to buy other things. 5 super potions and 5 repels will be fine for now. Skipe the train you can, fight the 3 others, and, oh, it's Emil! Dragon Rage will do an easy job. Just remember that even if it's easy to pass, some battles are worth retrying for better RNg, giving you some early finishings and you can economise pp. Use a repel to pass the moutain. Easy battles, I healed at the nurse, then skipped every trainer on the next route (except the first one) to fight Alex right away (just before, be sure to pass talking to the little girl in the house who gives you the charcoal, it'll boost your fire attacks). Even if you crit each time and one shot each of his Pokemons, the grail will kill you, so be sure to heal a way or another. If the nurse healed you, you can go directly in the gym, answering the 3 questions, and accepting the biggest challenge yet: Overheat. Finishing this gym fast needs big luck, Dragon Rage, and big luck. You go heal your pokemons at the Pokecenter and get ready for next.
In route 655, you battle the first guy, then take the bicycle (register it, you'll use it often simply to go faster), then battle the girl on the right. You can pass the last trainer by the bushes to skip the last trainer before Blake. But will you battle it? Good news, I found a way to skip it:
If Macho Brace would not lower speed, it would be effective. Otherwise, it is not.
Have fun trolling him, his recognition hitbox is pretty cool if you pass that way. You can then rush directly toward the next gym. Remember the TM Volkan gived you? It's Overheat, a powerful fire move you don't want to miss. You can skip the girl in the gym, and battle the 2 guys. I suggest to use Overheat on the Quilfish, it's simply faster. Now we are battling Spurge, yeah, it was fast. He, on the other hand, is hard. Use Dragon rages, and try to manipulate the RNG to force him to use less potions. A good thing to take note is that gym leader's pokemons have berry that restores health when their life bar is in the YELLOW. You can calculate strategies to defeat Pokemons in 3 moves or 2 instead of 4, per example. Same thing goes for the potions they use. Keep that in mind. Overheat should one shot the Nidoking. GG, we can continue the route. Go heal now, because you are fighting Alex again. It's raining, making Dragon Rage (again) more effective than Fire Spells. You should have Fire Fang by now, it's way stronger than Ember. Remember to buy 5 hyper potions and 5 super repel.
In the forest, if you past north, you just have to fight the ranger, then you skip one grunt and fight the female grunt. Fight the catgirl the best you can, and you can continue. Remember, for now, to NEVER have 4 out of 4 fire moves, at any cost. If you go against a Growlithe, Houndour, or whatever is immune to fire, you'll be in deep ****. Pass by north, you should have enough to go directly to the next city without problem. Heal, and go fight Emil who is waiting outside of the gym (doing whatever npc do I guess, just standing waiting for the player, it's pretty hilarious if you think of it). Pretty safe battle, you are strong for now, and fast. Dragon Rage will again prove his utility, but be careful: don't let Eevee steal you charcoal. You need that mineral more than you can think. In the gym, you can skip the third trainer, and fight the bug girl. FIRE EVERYWHERE. Piece of cake, you go out, and don't even bother healing, just go take your Lapras from the old guy in the ous at the south exit of this place. Give it surf, and you are set to continue. Zigzag and surf to avoid battles, and you arrive in "lightville". Heal, buy things you want, and get ready for some factory.
