How do you get Lugia in Pokemon Mystery Dungeon?

Answer 1

You have to get Zapdos (Mt.Thunder) Articuno (Frosty Forest) and Moltres (Mt. Blaze).

Talk to them once you get them (you might have to talk to Alakazam first) and you will unlock Sliver Trench (99F!) Make sure you have done these things.

You must of beaten him once (you can't recruit him the first time).

You need a small pokemon

Recruit ONE pokemon from the dungeon to help you.

You must be adjacent to Lugia and have given him the final blow (if you teamate deafeats him, he will not recruit you.)

Bring LOTS of food and reviver seeds

BRING a friend bow

BRING a trap scarf.

Good Luck

Answer 2

You cannot get Lugia in the Abyssal Ruins in Pokémon White 2. No Pokémon can be found in the ruins and Lugia is not available for capture in the game.
