Mhw 4th Farm Slot
Monster Hunter World Iceborne How to Upgrade Your Farm and Get The 4th Slot Once you’ve gathered 20 of these, head back to see Seliana and receive your next upgrade, which increases the capacity.
- To unlock all farming slots in Monster Hunter World, you need to complete 2 optional quests. The first one is called Persistent Pests and is a 4 Star quest.
- Remove all deco button I really like tbh. Also it seems just a repeat of our end-game grind base MHW is, deco grinding. Though I'm more interested in the drop rates of these deco's as thats a huge pool of deco to pull from tbh.
- Fastest Way to Farm 4 slot Decos (60-80pcs/hour) Duffel Duty.
