More loot. (Fallout Shelter)

Give them good armor and weapons and send them away to the wasteland and forget about them for one day.

Armor, weapons and pump them better according to stats. Ideally, you can still give an animal to increase the resistance to damage taken or to increase health. You send him to the wasteland and he walks there for two days. If he survives, then two and a half days, personally for me, is enough to fill the inventory to the maximum. Well, I have something like this) Good luck to you!)

I send a resident for 2-3 days, and if he dies (notification comes) you heal and send again
