I just got captured or whatever by palkia. Was not prepared for that. ..

Try to level up your Pokemon to at least 75. Try and find a Hunger Seed if you can and throw it at him. He will only inflict one point of damage. Try linking your moves as well.

It's imposiblle to find a hunger seed in there or to level up a lot as I know.So what you have to do is to go back to the entrace if you any sleep seeds or reviver seeds in storage because you can take them from the kangakhsan stone near the entrace then after you take oyt what you need try to not get defeated to much in the dungeon so you don't spend what you have.

P.s:I know it's hard to replay the first 20 floors but this is the only way if you don't have sleep seeds.

I did it with out any reviver seeds and only one totter seed, I had a level 70 pickahu and a level 70 charmander. All I used was dragon claw and discharge

I did it with a lv 53 mudkip and lv53 bayleef with only 3 oran beries and a stun seed, here's what I did:I went straight forward and got "ATTACKED!" when my hp is low the first time, I used an oran berry and went back one space 'palkia' followed so it's my turn again, used my best move then got 'attacked again' I used threw a stun seed at 'it' it got stunned'(if you're unlucky, it might not hit, it took me 17 tries before I could defeat it)I ran around the floor so I can get healed, I got to the furtherest tile I can get between palkia, then I used blizzard, it moved one space and I used it again, and again and then didn't remember what else I did, because after I defeated it I saved then my game "STUFFED UP!!" which I have to start from lv 5 again....... :-(
