Hey. Just wanted to share a good place to farm champion and elite mobs.
In act 3 you teleport to Tower of The Cursed level 1.
This only work for ranged classes!
The point is you stand on the ledge and they can't reach you.
Even teleporter mobs wont reach you.
I've been using this to farm in Hell as a witch doctor.
They tend to be quite hard to do the normal way for me with all the insane abilites
There is also a spot for this on level 2.
So just make a game, go check the spots out. If no pack you can just remake :-)
I've gotten a lagendary and a lot of rares this way, hope you get as lucky as me.
