That, and if you have Pain Inverter to use, should be all it takes.

Did it in 3 minutes on my Factions only ranger.

Seriously, look around, read the Wiki article about it. Your best shot is Echoing your celestial skill, having ur pet to ravage the shiro'ken. No conditions though, he returns them to you. Heroes = get a SS hero ONLY with SS insidious parasite and empathy + rez sig and ENERGY MANAGEMENT like mana drain or signet of lost souls. One warrior with Wild blow for the last 10% of his hp, be ready to click on wildblow, disable all other skills. Preferably for the war to get glads defence or sth with 75% block. NO CONDITIONS though. Pain inverter is very well advised.

key is the kuunavang skill, take it.
h/h definately possible. The problem atm is that heroes don't use/get the kuunavang skill but henchies do. So at least take more henchies cause they use the kuunavang skill. SS/SV nec heroes as above helps well (did it with my ele a month ago in hardmode)
goodluck

thanks guys.. I will try
