The blue princess dagger DEs into a large brill - that’s currently what I’m farming (obviously doing the WO run while I’m at it) for large brills, any better farms for 1-3 people?
I haven’t found anything reliable. I have been disenchanting wicked leather headbands at a chance for them and greater eternals with some success. I don’t know that there are any other trade items that are cheaper to make than leather that would give you a shot at the lbs.
If they’re for your personal enchants, just wait till next phase
