Goblin seems to want 50,000 beads for the Aeonic weapons.... Where would I get that many beads? I practically live in Escha for WHM and MNK job point soloing, and got a few thousand. Not even 10,000 I don't think.

I'm not against working hard for a good thing, but that is just an inconceivable number of beads. Unless there's some effective way of farming them that I never found.
