Ran an Imperium Maledictum intro and combat test to see how the system handles itself. I encouraged the players to go at it deep and hard. They got overrun by cultists before long and cut down, the last one standing being the psyker who proceeded to push his powers twice on a row. Built up an absolutely massive warp charge and, after getting hit with the Fatigued condition from a crit and rolling with disadvantage to contain his power, proceeded to then roll the max result on Perils of the Warp.
I understand a little bit better now why Psykers need to be culled.
