I haven't seen any ranger solo this before, if it hasn't been discovered and you want to use it just PM me ingame and you can post this video anywhere.
I use to farm him with a R/W build which ill post later if i feel like it :/, stopped farming him since the bow isnt so popular and my only interest in it was selling. All in all you got a nice build there, didnt think a Beastmaster could kill it.
