I haven't started any of the class specific challenges yet so I'm just concentrating on the Madness Auto to get another set of the Eclipse talis...
Been having to work too much today so the team I'm using with pretty good success is:
DDE: Fate / Chance
Baroness Redan : 4 Life / 2 shell
Prisoner: Primordial
Mag Lilith: Destiny / Immunity
Haven't had a loss in about 800 SoT but it's been pretty close now and again and I wondered how I survived.
I know there are better combinations out there, but this is all I had time for today.
Good Luck!!!
