I'll do some more testing after next patch to see if LUCK is working. But I definitely did not see any 'clover' pop out even always using player with luck 6 to open every container, and can't remember any magic items in basic containers.

I haven't done any save scumming, except at the well, so maybe I'll test that too on chests and such to see what happens.

But my original point in this thread was that with the well it seems if it gives random loot, it doesn't not happen at the moment you interact with the well. Loot is set sometime before that or is static. And was wondering if loot is set in advance on most containers, how do they implement Luck.
