lol.. so what? that happens like once in every 20 times... I hope that disnt dicourage you on your 1st attempt.

Nah, not discouraged at all, I find it very funny.
Anyway, I used this build:
W/Me
Empathy
Diversion
Mind Wrack
Spirit of Failure
Spirit Shackles
Healing Signet
Signet of Midnight
Sprint
12 Domination
10 Inspiration
Use a 20/20 Domination or Inspiration Wand / Staff is you like, just for faster casting and recharge
Maybe mix it up wand + foci to get fast cast and recharge on both inspriration and domination.
Bigger energy pool as well.
5 runs and nothing, guess I have to keep killing heheh.
7th run is hillarious, Oni gang spawn, but Thousand Tail's friend came and kick the Oni gang's rear ends, then Thousand Tail's friend left. In which I proceed to kick the Thousand Tail's rear end myself.
I prefer this build bcos it is kinda lag proof.
Connection is bad nowdays and I get hit with lag spikes often.
With this build, I can survive even when I got hit by lag spikes.
It is a modified version of Lint's W/Me Sskai farming build.
The build I use to farm various other bosses:
W/Me
Empathy
Diversion
Ignorance
Spirit of Failure
Deadly Riposte
Healing Signet
Signet of Midnight
Sprint
