Where do you recruit all the legendaries in Pokemon Mystery Dung
First of all, complete the entire game, including Darkrai and Regigigas. You should have Cresselia already. After this get a Wonder Mail code for a Golden Mask/Amber Tear, a code for Mystery Part/Secret Slab. Here are the codes.
Golden Mask: 7#RW &&-6 @03R &X02 5SY@ -155
Amber Tear: 9@9# -+3J RF+& &3=F %080 @-@H
Mystery Part: M-M6 CCKY 6Y@P %54P R0P+ YWCJ
Secret Slab: &1@X 2FM9 +36P 6255 =9@Y M#F%
Also, after Manaphy leaves, sleep a few days, and he will come back and join your team. Sleep a few more days and you will unlock the Marine Resort. You must do a mission each day. You will need this dungeon to unlock the following.
You also must have completed the Froslass mission. Talk to Mr.Mime at the Kecleon Shop and you will gain access to Blizzard Island. Rescue Scizor and he will promote you to the Secret Rank. You can now take Wonder Mail missions such as Shimmering Desert, Sky Stairs, etc.
Darkrai lost his memory after Palkia shattered the Dimensional Hole he had created with Darkrai still inside. I recommend going to Miracle Sea, 3F. Be sure to take your Golden Mask/Amber Tear and your Mystery Part/Secret Slab. Pack some Oran Berries and Escape Orbs, as well. After you reached 3F, Send Home all of your team members. Then, walk around until you find Darkrai. Make sure you have the Golden Mask/Amber Tear equipped. Defeat Darkrai. If he doesn't join your team, use your Escape Orb and repeat the process until he does.
Go back to Temporal Tower. Defeat Dialga for the second time and he will automatically join your team. You do not need a Golden Mask/Amber Tear or a Mystery Part/Secret Slab.
Same as Dialga. Go back to Spacial Rift. Defeat Palkia and he will automatically join your team. You do not need a Golden Mask/Amber Tear or a Mystery Part/Secret Slab.
You will need a Shimmering Desert Wonder Mail.
Shimmering Desert: #&S6 NY2& YJN= 1P57 F0MN MH7Y
This has 10 floors. Defeat Groudon. I suggest bringing a Golden Mask/Amber Tear and Oran Berries. Bring a Pokemon that can protect against monster houses (Ominous Wind, Discharge, Roar of Time, Spacial Rend, Silver Wind, etc.). After you defeat Groudon, you will receive an Earth Cymbal. This increases the recruitment rate for Ground Pokemon. Groudon might reappear and decide to join your team.
You will need a Sky Stairs Wonder Mail.
Sky Stairs: HW+8 66%T 5S51 +J5Y 4-K# H@P-
This has 50 Floors. At the Sky Stairs Apex, defeat Raquaza. Its recruitment rate is very low, so bring a Golden Mask/Amber Tear, but BE CAREFUL! You might be defeated from Ninjasks, Salamences, Misdreavuses, etc. Bring plenty of Reviver Seeds. If you defeat Raquaza, you will receive a Flying Pianaca.
You will need a Bottomless Sea Wonder Mail.
Bottomless Sea: FN01HWN-00%F 8678 +XY@ &%#3
You will need a Bottomless Sea Wonder Mail. This dungeon has 50 Floors. At the end, defeat Kyogre, and you will receive an Aqua Monica, which increases the recruitment rate of Water Pokemon. You can bring a Golden Mask/Amber Tear if you want.
You will need a World Abyss Wonder Mail.

This dungeon has 30 Floors. Defeat Giratina to receive a Rock Megaphone. You can bring a Golden Mask/Amber Tear if you'd like.
You will need a Mt. Avalanche Wonder Mail.
