Fly back to Ecruteak City and head out of the city to the East to Route 42. Swim out to the East stopping at the first island. There are Apricorns and also Suicune. Suicine will run off yet again and so Eustine will show up YET AGAIN. No battle this time, just more talking. Then keep working your way East to Mahogany Town
Not much to do in Town at this time since the Gym is closed. Head to the East to buy a RageCandyBar for 300. It's a Key Item you are going to need later. Then head out the North to Route 43.
You can either pay the toll at the Gatehouse of a 1000 or head through the Grass. It's your call but the grass means Pokemon which means EXP. This is a rather long area that contains a lot of Trainers. Continue North to the Lake or Rage.
Lake of Rage
Surf out into the Lake of Rage to find the Red Gyarados. This is a Unique Shiny Red lvl 30 Gyarados so if you want to catch it make sure you save right before hand and have a GreatBall ready. I'm not the collector type so I just took him down. After the battle you'll get the Red Scale. Then head to shore and talk to Lance. The Red Scale can be traded for the EXP Share with Mr. Pokemon above Cherrygrove and I suggest you go there now to do that. It gives one of Pokemon half the EXP for not being in the battle. A great way to level up lower level Pokemon. Then fly back to Mahogany Town.
Mineral Badge - Lake of Rage
Mahogany Town / Rocket Hidden HQ
Head to the small store and Lance will already be there. He finds the secret stairs and you follow him down. As you head left past the first statue it sounds the alarm and brings two Rocket Grunts at you one after the other. Don't worry though you can turn these off. (Alternately leave them on for extra battles and extra EXP.) Head left and down and then follow the path to a Scientist. Beat his 3 lvl 20 Magnemites and then use the computer to turn the security system off. Then head back to the main path. A Grunt will be up ahead for you to battle. Then continue on and head down the stairs to the next level.
On the second floor Lance will heal you up. Then continue to the right get to third floor.
Lance is just always one step ahead of you. He's already gotten the first part of the door code. Head to the giant room on the center and fight the female there to get thepart of the door code and then a grunt to the bottom left. Now go to the upper right to get to back to the second floor.
As you go around to the door your Rival will show up to talk. Just talk. Then use your new found codes on the door and go in and fight Petrel.
lvl 22 Zubat, lvl 22 Koffing and lvl 24 Raticate vs. lvl 38 Typhlosion
My 38 Typhlosion destroyed his entire team OHKO style. As always if you are having any problems with battles look up the Pokemon on the Supercheats.com Pokedex. After that follow the Murkrow back to the first floor door and it will unlock it for you.
BATTLE: Arianna & Grunt vs You & Lance
The Murkrow will get you in so you can fight Arianna and a Grunt. Lance will show up to make it 2 v 2. Lance has some very high level Pokemon so no matter what you have if you can just survive he'll take them all out but my lvl 30s stood their own.
After that battle you need to head up the left side and take out 3 lvl 23 Electrodes one by one. Then the system will shut down. Then head to the Center to heal and go to the Gym to get your next badge.
