Around 10, i think
he is at the end of spacial rift which is 20 floors in spacial rift 10 in deep spacial rift
I think it has 20 first floors and in deep spacial rift 20 floors and that equls 40.
10 floors True but really 9
Spacial Rift has 15 floors. After Spacial Rift, Deep Spacial Rift has 9 floors. Finally there is the boss room with Palkia. I recommend using the same strategy as Dialga, but Palkia has different strengths and weaknesses. Here they are. Strong Against Fire Ground Rock Dragon Weak Against Dragon
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!
15 then 9
80 levlels
20 floors in all, counting the boss floor. 10 top, 10 bottom ( but really the bottom has 9.)
As soon as you enter there will be 15 floors then after the middle part then there are 9 floors at the end is the boss Palkia
After defeating Palkia in the Spacial Rift to continue in the story-line, you must go back to the Spacial Rift any time later in the game and defeat Palkia. Upon doing so he will ask to join your team.
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.
after you do the nightmare which is 20 floors by the way do a couple missons and then you should be having dreams then 1 night palkia will come in your room and take you to spacial rift you will fall off the cliff and go through a dongeon which is 17 floors + 10 in deep spacial rift and after you beat palkia you will go home and will unlock spacial rift so go through it again and if you beat plakia he will want to be on your team ps. palkia is just as strong as dialga whatch out!
