This writ is easy enough to complete. There is a safe spot next to the crate on the left hand side of the road, just past the 2 green hood scouts, as you make your way from the outpost to 3 toes lake. 2 raiders will pop in the glade directly across the road from this safe spot. 2 more raiders will pop north of this glade. Watch for road guards and lugger adds as well as patrolmen and lions on the more northern group.
Takes about an hour to complete the writ.
