Is it possible to find power armor in the wasteland?
If you send somebody out in the wasteland for long enough with good enough luck, is it possible to find power armor or any other legendary gear?
Yes it is possible, I have found Legendary outfits and weapons while exploring the wasteland. It is definitely easier to find gold gear in lunch boxes, but it is still possible to get really lucky while wandering.
To be specific, I found a "Heavy Combat Armor" (4S 3E) in one vault and an "Tuned Alien Blaster" (18-20 dmg) in a different vault.
