[Non-Renewal] [Ask] How do you kill Kathryne Keyrone on HighRate Server 99/70?

[phaiest]

So, usually on high rate server,
you got Warper NPC, Healer+Buffer NPC,

But I still can't find a better way to kill Kathryne Keyrone on biolab 3.
She is a ghost element, so Ashura Strike /  GF is useless

The only way that I know to kill her is using Assassin Cross
I made this build like this :

as you can see
For you to be able kill her in 1 SB, you need :
Assassin Spirit + ElementScroll/Endow + EDP

I need to farm the for Scroll and Poison Bottle,
And also, 
Everytime I activate an EDP, I only have 1 minute / 60 seconds before the effect wear off,
Sometime, I couldn't find KK in sight



I'm wondering whether there are other way to kill KK.

Well then start farming those mats for EDP then. High rates makes that hardly a problem

I'm surprised no one have replied to this..

Even in a high rate server, you have to do the traditional way which is to lure it to ledge and then use sniper to spam double strafe while having someone (champ) with it in the last cell while having someone ice wall. Funny thing is I never managed to beat BIO 3 MVP and when I almost did we had no sniper LOL

At 130 STR you could use +5 slotted element katar and drop that porcellio card. This remove the need to convert / Asper. EDP is mandatory. If your server activate pet effect , use smokie.
