Muqqadas weapons were implemented here, but they are generally outshined by Dim Glacier weapons. However, their farming requirement is significantly more, requiring 5000 Fragment of Pollutions and 4000 Sources of Pollution just for the base weapon while also being harder to farm.
My suggestion is to increase Mob Density in Power Twisted Plains or increase drop rates of the mats or both.
Additionally, I saw the changes as part of https://forum.muhro.eu/d/258-patch-notes-39-02-june-2022, and I would also like to suggest an increase in the Shadowdecon, Zelunium, and Etel dust drops in Power Twisted Plains and Mjolnir Underground Caves maps. Both are supposed to be late game maps (with higher level requirements than nif 2 and clock tower) but are rarely accessed since they are completely outshined in terms of farming against those two.
Generally, I think having more farming maps would be better.
