in order to open the door at the sootopolis gym
u have to capture GROUDON. u cant enter the cave where groudon leaves because a man wont let u. u have to go to an ohter cave where team MAGMA is. team AQUA is there too. after some battles u will have to battle the leader of team MAGMA. he will use an orb to capture GROUDON but it will fail. then go to sootopolis. at the left island enter the cave and reach GROUDON. try to capture it. i dont know what happens if u dont but i suppose its the same. then u can enter the gym after a short talk with Steven. ^^ i hope i said it correct :x
In ruby and sapphire, the pillar is automatically unlocked after beating the elite four. In Emerald, it is unlocked after seeing Groudon and Kyogre fighting in Sootopolis City.
you eat pie
you have to distory the door
You dont open doors. Theyll be open or when you walk into one youll go through. Some doors may be locked and youll have to find the way to open them.
yes, and also having a wailord in your team
well i forgot
You have to catch Kyogre and Groudon.
The "Six Dots" reference the amount of eyes on every "Regi" you find behind the "3 doors"
Sootopolis. You have to go through the whol Kyogre episode then the gym will open up. (Sootopolis is the white place you have to dive to get into.)
It means that the three doors are to Regice, Regirock, and Registeel.
I don't think you can get regirock in pokemon ruby.
First you need to awaken rayquaza from the sky pillar on route 131 which stops the fight between kyogre and groudon then the doors of the gym are open to you
