ok done dual its about 3-4mins/run using 2 perma slivers one going for wiseroot and one for scareater. the one going right(scareater) meets 2 groups of foes after 1st sliver a 3rd group joins. usually is the time when the 2nd perma going left (Wiseroot) have balled all groups up around him, as soon foe counter hits 12 1st perma goes for (scareater)
since sliver always target that boss you get the skill recharge so wiseroot perma gets to use sliver again faster. and the trouble of targeting wiseroot is what gives the extra faction and while the wiseroot perma try to kill him, the scareater perma finish of his groups. Usually ends up in 30-40 foes killed. 35x20=700+250+250=1200.
also both permaslivers use same builds atleast i do with my guildie.
that way if one being unlucky and dies the other can finish it and when the "dead" perma maps to town other one gets his wanted drops. so no need to wait for res.
perma skills
GolE
Ebon battle standard of honour
Sliver
ear bite
brawling headbutt
last 2 skills target wiseroot

to help speed up run until sliver targets him.
if you see a hex (blurred vision) move away...or you are dead if more than 2
dragon roots or wiseroot targets you, if you cant, try to kill the minion with lowest hp fast..
drops are gothic weapons but all seems to be 15%vs hexed:P
elite tomes, alot of materials (granite, plant fiber, spiritwood)
and the white/blue/purple merchfood.
other downside is you can only farm faction when the right faction owns the place.
when it dont i just play the game.
and primary, like most people i used this for tome farming but tested with a guildie and noticed it can be used to farm stuff and faction at a decent rate at same time.
and there is.
better places to farm faction
better places to farm elite tomes
better places to farm gold drops
better places to farm materials
