After testing my various army builds over the past few weeks against some friends, I have come to the conclusion that the Imperial Psyker Battle Squad is the single, most powerful unit in the IG army by far.
Here are some things I have done with the Psyker Squad so far, in no particular order;
1) WR + DP = Turn 1, 15 strong Necron Warrior unit with Lord forced off the board.
2) WR + NS = Turn 4, Callidus kills 8 Plague Marines, and finishes off the rest in close combat, taking a super tough unit off an objective
3) WR + NS = Necron Lord and Immortals Deep Strike near my lines. Next turn, Callidus shows up, and all but 1 Immortal and Lord killed. Perma-fall back.
4) WR + NS = Callidus kills 7 Nob Bikers, forces fall back off table.
5) WR + Shooting = Forcing a Morale Check from shooting usually means death to a unit
6) WR + Pur = Guaranteed way of dropping an IC's LD to 3 for entire game. Worked great on Marine Commander after Callidus killed entire retinue with Neural Shredder.
7) WR + DP = Got a 20 something strong Kroot unit out of a forest and off object, securing the win for me.
WR = Weaken Resolve
DP = Divine Pronouncement
NS = Neural Shredder
Pur = Purgatus
When I use these combinations the games are pretty much not fun for me, and especially my opponent. But I can imagine the Tournament fun you can run with these guys.
So far, the most potent base for a Psyker Army I have come across consists of;
1 Inquisitor Lord w/ DP and random Retinue
1 Callidus Assassin
10 Psyker Battle Squad (with or without Chimera. I use a Chimera for protection)
10 Psyker Battle Squad (with or without Chimera. I use a Chimera for protection)
What else can you come up with?
