stock up huge on reviver seeds get to maybe level 60 (ur fine at that level) and get a
move that can affect at least three pokemon (such as lava plume, wide slash, discharge,
roar of time etc) p.s. recruiting and using dialga for this battle helps a TON

forgot to login lol

I thought you couldn't bring any extras on that...?

Icicles, who exactly said that? =P

Have dialga on ur team and let him use roar of time it should be easy and for your
cyndaquil just keep on making him use lava plume that helps alot. I beat him with a lv 45
piplup and 44 cyndaquil its pretty easy

I would get a bunch of moves that can affect everyone in the room. Some examples are roar
of time, vacuum cut, and discharge. Bring lots of reviver seeds, and oran berries. Oh, and
I might just be crazy, but I thought you couldn't bring partners. It wouldn't let me.
Doesn't that include dialga? Oh well. It doesn't really matter. Just get out there and try
your best!

The best way to recruit Darkai is;

1. Be on Super Rank or above
2. Be close to Lv. 60
3. Have the Friend Bow

I recruited him in the Spacial Rift.... with Latias on the team...

The random pikachu is right. Only bring one pokemon with a one star body size. It makes
other pokemon easier to recruit.

Like I said, the Spacial Rift is the best place to recruit legendaries. Latias is on B10F,
Darkai is between B14F and B17F, and Latios is in the Deep Spacial Rift B2F.
