As well, mobs' body parts that require incapacitation usually always sell well/decent. PGL's Concussive Blow will knock the horns off Aldgoats (East of Horizon) and Antelopes (Southeast of Tranquil). At one time, I was making 2m/hr. from incapacitating Green Megalocrab Shells when Crab Bow HQ was the hot item. The Wandering Wights in Mun-Tuy drop Steel Ingots fairly often, and there is a concentration of 10 of them in the upper Southwest corner. Wolf hides NPC for 600g each, often dropped by a group of 6 just to the Southeast of Humblehearth.

Used to be that I would look at the most coveted gear ingame, find its materials and/or the item itself and go get it.
