Not entirely true. Some sources are restricted to Purple or E-Tech at best. White Chests and their other manufacturer counterparts (Hyperion Yellow, Dahl Green, Bandit Toilet? Yuck) cannot contain Legendaries or better as they follow a different RNG system independent from the normal world drop one.
In three years nobody has ever found a Legendary in them.
Otherwise, if it can spawn a completely random drop then it can be Legendary or Pearlescent which most of the dirt piles and similar sources do.
Need to add the red pirate chests with a big 'ol check mark by them.
If it’s an “ammo” or “money/eridium/health” chest, that doesn’t otherwise have a chance to spawn a weapon at all, there’s also no chance for a legendary one (I’m looking at the little Dahl and Hyperion strongboxes). In principle, this list should just include items that have a chance to spawn a weapon, just not a legendary.
Also, I take it the chest wouldn’t count if, while it can’t spawn a legendary item on its own, it can spawn a LLM, who then drops a legendary item?
you can add a check mark to the green piles on the ground I just took a video clip of a legendary popping out of one the other day. If you are on xbox one you can verify it in my clips GT: lissybaby001
are missing from the OP. They can contain Legendaries, I’ve found a few myself actually, but I’ve never seen a Pearls in there. Maybe someone has as it should be possible as they appear to be no different than ordinary enemy drops in terms of quality (and even boxes got some…).
I’ve gotten 2 pearls from lockers. Oddly enough, they were both in one of the lockers right by the entrance to the Torgue arena outer circle, and they were both Stalkers.
FWIW, I’ve never gotten a legendary from a stalker pile, etc., but I did get a Topneaa from a skag pile once. I don’t know where it was hiding.
Actually, enemies and chests are incapable of dropping Legendaries before you enter Three Horns (Normal Mode only of course).
Random drops are rarity locked entirely in the first few areas and I am pretty sure I’ve never even seen anything better than Green in Red Chests there.
Hornet, Bonus Package, Kerblaster and Thunderball Fists (and technically his Skin) are assigned drops and follow a different system so they aren’t bound by world drop restrictions.
