Beat Drarkrai
Well, you need to be able to get to the Special Rift, and second, you need to explore it fully a second time, and then fight Palkia. When you win, he will then request to be part of your team.
You have to complete the game fully, including the post-game plot and unlocking the Marine Resort dungeon. Spacial Rift will also reopen, it will not mention this, but it will now be on your location list.
kourosh
well we can't but you can battle palkia! he is in special rift
Defeat him at spacial rift then go back there and beat him a second time he will join your team probably.
First you have to beat Palika for the first time then you have to go back to apacial rift and recruit him. Dont worry he will join after u beat him for a second time
19 or so floors
Yes
first you have to find out about the distortion of space and then talk to lapras then that night palkia will get u to spacial rift.
The nightmare Then the spacial rift(also known as the sky rift)
If you're talking about Spacial rift it has 10 floors. This is posted by Swampert32:- The answer above is proved to be wrong. The actual number of floors is 15 and the second part of the dungeon (Deep Spacial rift) is 10 Floors! Hope this helped! :D :D Ps- Rate this as the best!
Just go to the right in crossroads (south of the guild above the beach) so you can go to a dungeon, scroll down the list until you see spacial rift and you pass 15 floors then about 8 floors and then spacial rift bottom location of PALKIA battle him\her he has about 650 hp the second time you battle him.
