Elite 4

From Lacunosa Town, go to Route 13 then enter the Giant Chasm's cave.. Now heads toward the west, you will see an exit here.. Now, you will be on Route 23.. You will meet lots of trainers before reaching the gate.. Before you reach the fancy gates, you will meet N who will give you Waterfall HM.. Now go through the road till you reach the gates that check all your badges.. Heal your Pokes and buy lots of healing items.. We are heading to the Victory Road BW2 version..

You will first go through a nicely decorated underground.. Once you have reach outside of the cave, march toward the north.. You will eventually see a doctor outside of another cave.. Go inside the cave and head to north-west.. If you go to other exits, it will most probably leads you back to the "nicely decorated" cave.. Through you will get items in process, so it's up to you whether you wanna explore or not..

March all your way to the top.. When you enter the old Victory Road's cave, your rival will ambush you for a battle.. BUT! You should be glad, because the moment you sees him, it means you are just few steps away from Elite 4! After defeat him, you will get Thunderbolt TM from him.. Get out of the cave.. Head north and of course, here's the Elite 4..

Buy LOTS of Super/Hyper Potions, condition items and Revives.. For those who are using Emboar, you might want to get Arm Hammer from Remember-old-move in PWT.. X-Scissor is pretty a must for Serperior.. Serperior will totally be useless against Iris, so for those who use it, you need tons of hard work on other pokes..  Samurott shouldn't be a problem, since it can learn Ice Beam..

Like BW, you can challenge the Elite 4 in any sequence.. IMO, it doesn't matter which one you battle first though.. It doesn't change the fact you have to face him/her later.. They will be using 4 Pokes each with lvl 56~58.. The champion will have 6 Pokes with lvl 57~59.. The first will be ghost, second will be dark, third will be psychic and fourth will be fighting.. Iris will of course be dragon-type.. After each battle, heal all your Pokes with your items then save before entering the next room..

The real shit comes from Champion Iris.. She started with Hydreigon, I would highly suggest you kill every Poke she uses within a turn or two cause most of her pokes hit hard.. Be alert that she has wide type usage, means she can hit you by weakness more than you can do to her.. So yea, speed is important here.. Her trump, Haxorus, will of course be the deadliest here.. It will be holding Focus Sash, so OTK won't work.. Don't ever let it Dragon Dance twice, you might need to turn off your Ds if she did that..

After you have won, it will be the Hall Of Fame time.. Then you (automatically) leaves the Elite 4 with their escort.. The credits will then roll, while showing you backtrack all the way back from where you came from.. You will visit the gym leaders from the last to the first one.. And eventually meet up with your mom.. The End... And welcome to the Post Game.. :)
