I need a stealth boy. Ive gotten all from repconn headquarters andthe one in goodspring school. Ive checked all the vendors I've could. If you know anywhere where I can find one, or where I can find nightkin (not Jacobstown or the cave north of Jackobs town), it would be a big help. If thier was one in the abandonded shack north-west of the Yangtze Memorial, I got that one to.
Vault 11 had quite a few, I believe, especially considering the last part of it, which in part necessitates a stealth boy practically. Other than that, not sure. Maybe Black Mountain, considering the Nightkin there, but since I haven't gone through it yet, I'm not sure.
If you're messaging me about a dog I really have no idea, sorry
