Dark Moonstone of the Covenant Farm?

[N33T_1337]

Has anyone found a reliable way to farm it?

You can buy them off Poledina if you give him the final krat supply box

There is a finite number for sale even after all things have been given. They can drop from broken puppets and ballerinas rarely. I think they can also drop from spiders. Basically enemies in the rose street or opera house drop them rarely. Realistically though, it's faster to just go to NG+ to farm more. It's full moonstone of the covenant that are the real issue. You only get 6 on NG and 7 on NG+ (the extra is from the 4th trinity room on NG+ and beyond only).

Unlike normal weapons, you need full moonstones of the cov for both +4 AND +5 so your weapons are pretty gimped without them compared to leaving a normal weapon at +9. You need 1 for +4 and 2 for +5.
