Teleport from Aden GK to Blazing Swamps. Proceed south east (more east than south). On the map it is in the general area listed as "Fields of Massacre". It is actually due south of Disciples. You will see Wretched (formerly and incorrectly "Wrecked" in a previous chronicle) archers aplenty just over a grassy hill. If you see Grave Predators and Doom servants, then you're in the right general area.
The archers like to hide in trees, so be careful when you attack one that is partially visible near a tree. There may be another one just out of view. They are easy enough to kill, especially if you are a melee class.
If you're looking for C grd stuff you chose the wrong Archers since they drop B grd items, Doom Scouts drop Dark Elven Long Bow and Grave Lich drop the Avadon Shield.
For C grd stuff like Karmian Tunic and stocking you will have to hunt the "Archer of Greed" located right before Cemetary which is near Aden. They are surrounded by Ratmen Thieves who drop the Great Helmet and a zombie mobs who drop the Dwarven Chain Shield. ;)
Right outside devastated castle , opposite side of doom knights. Grouped with , doom scouts and graves liches. Doom scouts are aggro, also the liches and archers are social to each other.
