I farm this one spot, because it seems unique in the game—maybe it’s not?
When rescuing Lucky, there are two white and one red crates that seem to have a decent chance to offer up a unique item, if not a quality purple or blue at or slightly above the player’s level. The range seems to be six levels below to one level above player level. The weapon vending machine also appears to have a chance of offering a unique gun.
For a while, that is. It seems there is a countdown modifier affecting the odds negatively. What I’ve observed is that after opening the crates and using the vending machine, one can exit to the main menu, restart the game, open the crates and buy from the vending machine anew—without enemies around. But it seems to me the chance of getting anything noteworthy diminishes over time.
You can do this so long as you do not turn in Road Warriors: Bandit Apocalypse. Once you turn the mission into Helena Pierce, enemies will again spawn at Lucky’s. You can farm the crates, but not without a fight.
Of course, the odds described are anecdotal. I’m just reporting observations. I think it’s a cool trick, because the game gets a little harder once New Haven is reached.
All of this was to ask if anyone else out there farms these crates, too. And, if Lucky’s isn’t unique this way, where else does this happen?
