Of the 4 options: Divination, Pyromancy, Telekinesis or his three powers, Hammerhand, Sanctuary, and Dark Excommunication, which powers would you choose?
I'm leaning towards Divination hoping to get forewarning or putting him with a blob IG and use perfect timing but I can't decide. I've never really used psykers before but heard good things about putting him together with IG.
How do you use him most effectively when allying with IG?
Any advice is appreciated!
