2 Dexxers could probably take her down in less than 20 minutes. I know with Four accounts You can kick her around in under 8 minutes (ninjas included).
Fastest Way with a group Is to
Have all Melee In wraith form
All Melee with area Weapons
Honor it with your bush guy (Obviously),
Lure it in between a pole and A Wall.
Now, the beauty is that you can stand on the other side of the pole and she will never turn into you. You can summon all the ev's you want/bless/cure/heal your melee guys without having the travesty running around. THIS includes Disco. Just step out, attempt discord instantly step back. If it succeeds she is discorded and so long as you are on the other side of the pole she never steals the ability from you.
Try not to Use Bleed Weapons/Mortal Weapons
Also Steals AI, Concussion, Crushing but I don't view those as as big of a threat.
Lightning strike doesn't do any extra damage, but it does increase your hci, so it can be nice

.
Trick is to Always Have Consecrate/Enemy of One going so you do max damage.
Best support for the dexxers is a Tamer With a runebeetle and mare/bake. Runebeetle lowers the resists and increases the damage alot!
Fastest I've Ever done it was with 3 Dexxers and a Tamer, was about 5 minutes. Beat it so Fast we killed the spawn, looted it, went back in and waited at the table for a minute for the Key to go way.......
With the right scripts you can run this on your own
