After you beat dialga there are several things you must do. If done Cresselia appears in your dreams a little while after Cresselia appears you have to do a few things then the night you talk to Lapras Palkia appears and takes you to Spacial Rift.
You get Palkia in a dungeon called spacial rift.
Spacial rift 12f
spacial rift
You find him in spacial rift.
he is at the end of spacial rift which is 20 floors in spacial rift 10 in deep spacial rift
I dont know losers U suck
chatot tells you about palkia and when you go home palkia comes in and brings you to spacial rift.
you have to get hit 99 then it will work.
To unlock the Sky Stairway dungeon in Pokemon Mystery Dungeon: Explorers of Darkness, you must first recruit Uxie, Azelf, and Mesprit. After recruiting them, a new dungeon called Spacial Rift will open up. Complete Spacial Rift and then Sky Stairway will be unlocked. Good luck!
Giratina is found in the final dungeon of Pokemon Mystery Dungeon: Explorers of Darkness, named Spacial Rift. It is recommended to be well-prepared with strong Pokemon and items before attempting to face Giratina.
to complete Explorers of Sky, you need to defeat Darkrai (with Cressilia on your team) in dark crater after defeating Palkia in the spacial rift.
The same way you do in Pokemon explorers of time. You have to go to some mission in the spacial rifts then you have to be the person to hit him last, if your partner hits him. It will just say you defeated Palkia, oh and I don't remember how to get the mission on the spacial rift, nor do I know how to get the dungeon. Well, hope I helped. :)
