This grid will farm the material’s required for Manasilver Choker. This Levequest allows you to hand in 3 at a time so it wont drain all your allowances. You will need Mining, Botany and WVR for this to work.
However this grid will not farm Twinthread. You will have to buy 10 of it off the marketboard before you start the scenario. 1 Twinthread per Choker. Just sell a choker after running the scenario to cover the cost.
