One line from the Update 15.2 patch notes caught my eye: “A couple of warg dens have been added to the Lonelands to make finding wargs easier.” I did some research and found two new dens with rumors of a third, but after extensive searching, never found it (Forochel all over again). If you know of any other new dens, leave a comment below.
But these wargs dens only have eight wargs each. That’s not enough for deeding by itself, but as this player suggests, it’s probably best to do the warg and crebain slayer at the same time. I’ll go a step further and suggest that if you grind wargs in the east, do crebain, orcs and maybe spiders simultaneously, and if you grind wargs in the west, do it with the goblins.
