I have found an exploit , its about a wreckage near a portal , i have screen shot of location on map.
The wreckage is located in the Vulture Drift (near Arid sea portal
This trick is Very easy for Any Warrior
U need Points in tactics
U need Sprint
U also need Balanced Stance ( to avoid being knocked out by sand wurm)
The colored lines represents different things :
Blue lines representes the easy part of the run
The yellow lines represents the Hard part (Sand wurm, use balanced stance)
The Red circle and Arrow representes the location of the wreckage and the portal u got to cross again and again.
