Welcome to Librarium Online!
Ok what should I buy next to add to this force of sisters:
2 squads of 11 sisters
any suggestitons are welcome
i would consider buting the candian battle force
you get a leman russ infantry platoon plust 3 heavy teams
in adddtion i would pick up an armoured fist squad or two
third idea would to buy a couple whfb empire detachment boxes and play them as zealots
More Sisters and another exorcist
2000pts Orks 4-2-1
Another Immolator, 4 Retributors w/ H Bolter and an Imagnifer and a VSS.
"The sword that takes life gives life."
I'd definitely invest in more Battle Sisters, plain and simple.
You could probably get some IST's if you're not picky.
nah, get some more sisters to bulk up your army, and you already have alot of elites, so you dont need anything there, along with HQ
you could even get some more sephraim
Fill up the rest of your seraphim. And rhinos.
And over there we have the labyrinth guards.
One always lies, one always tells the truth, and one stabs people who ask tricky questions.
