5.35 Bozja - You can't level down from mettle

[Driavna]

If you find one, please let me know. If there's a way like there was with the one lockbox farm in Pagos I'll gladly do it

Kill mechanical enemies at the starting/mid area and do any fate (are more common in the area I mentioned) involving the same type of enemy. The more people doing it the better, since everyone gets the item if it happens to drop.
