Hey all. Every guide says that Grey Pigment comes from logging lvl 30 mature trees in the South Shroud. My Botany is at 67 and everything is 100% drop rate.

I've cut down maybe 20 of said trees and not seen a single Grey Pigment.

I always use Luck Of the Pioneer to uncover hidden items but so far I got nothing.

Am I doing something wrong or is Grey Pigment just a particularly rare drop?
