Think just the torque ones likely, not even sure the loot is even right for those, since its suppose to always drop 2 right?
Jungle Boogeyman loot pool seems to work, we got 2x torques and a bunch of other drops.
I think Amphibian assault works as well, but haven't personally done it.
Legion XI Comitatensis does NOT work properly, one run we only got 2 total items, 1 torque.
Which makes me suspect he could have added the lynx leather into the loot pool since he clearly screwed with drops. Either he did it wrong, or he made it absurdly rare, like oxblood orb, so <3-5% droprate. Would need to do a few dozen runs to confirm if the lynx leather is there or not, and I don't think people want to burn 1000+ seals just to test it. Especially when it's equally as likely that he left it out of game and its currently unobtainable.
