Hunt 8 a highland chargers. (-102, 103, -169) and ( -90, 107, -198 ) Copy/waypoint -90, 107, -198
Note: One source of Highland Chargers is to stand at ( -121.12 49.80 -23.81 303.22 0.00 0.00 ) and look over to the pillar that rises out of the water in the oasis. There is usually one up there. Targeting and pulling it with a mercenary (I was using a flying one, and I needed to tell it to back off once it got there,) will bring it down into the oasis so you can kill it.
Note 2: Another place to find Highland Chargers is ( -19.57 107.66 -310.02 ) inside the Raj'Durabad area.
Gather 8 Wild Bulgur Wheat. Often in between the tents of the Raj'Dur. ( -176, 107, -209 )
Find the silenced detractors along western edge of the Kalickia River ( -127, 100, -395 ) Copy/waypoint -127, 100, -395 (look for a Red Banner-Flag on a cliff-side right by the top of the Falls). This is an auto-update when you approach the Skeletons on the pikes.
