I am starting my first ever DH PC and chose Void Born Imperial Psyker.
With a WP 50, I am able to start with 3 minor psychic powers. As of right now I took Lucky, Unnatural Aim, and Inspiring Aura. My thinking here is that my character enjoys using his auto pistol so Unnatural Aim could come in handy.
Lucky, I really just picked for no good reason.
And Inspiring Aura I thought would be good to help boost up the team when the **** hits the fan.
My question is, in your experience what minor powers have come in handy time and again and what are a complete waste of time/"Oh God why did you pick that? It is Warp bait, stupid!"
