Diamond Farming

2x Abyss tablets with "Map is inhabited by 1 additional Rogue Exile" and a Unique tablet Unforseen Consequences paired with Shadow of Undeath atlas passive give you a big chance to get Diamonds from Rogues.

If you get a Desecrated Currency mod on your tablets you get a lot of bones and Omens too. Omens of Abyssal Echoes (~3 div) is pretty common.

Tablets with Rogues and Currency are 9-10 div each and Unique tablet is 5-6 Annuls, You can get that back in the first 2 maps, rest is pure profit. If you play cleansed maps you can get Fracturing orbs (~33 div).
