In HeartGold, you have to go to Pewter City and there will be a man who will give you the wing. In SoulSilver, I think you have to get all eight badges, but I don't know for sure.
To catch / find Lugia
For Ho-oh you need the Rainbow wing For Lugia you need the Silver wing
I believe it is after you catch suicune that you can obtain a silver wing.
If you want to catch lugia you need silver wing, tidal bell, beat all the kamino girls, complete all eight gyms
Yes you do.
To catch Lugia in HeartGold, go to an old man atop a slightly raised platform in Pewter City. He'll give you the Silver Wing. With the Wing in your Special Items pack, go to the Whirl Islands and find Lugia in there. Lugia is at level 70.
Once you have the Silver Wing and Tidal Bell you can go to Whirl Islands to catch Lugia.
yes once in viridian city a man on a platform will give you the silver wing. you can then go to the whirl islands and catch lugia at level 70
you need a silver wing
The Silver Wing in Pokemon Silver lets you interact with Lugia in the Whirl Islands to fight and catch it. Lugia can be found in the deepest part of the Whirl Islands.
To catch Ho-oh you need a clear bell and the wing. For Lugia it's the silver wing and a tidel bell.
Go to whirl islands and catch Lugia..! Good luck!
