So I think I might have broken Mechanicus, because the boss fight against Void Admiral Agrolekh was such a resounding victory for the Adeptus Mechanicus it was honestly surprising. One Kastelan Robot deployed in front of him, and four Tech-Priests hiding behind it, furiously healing it with advanced level Curatio Mechadendrites. It was bad enough, but then I played the Canticle that allowed 6 attacks to ignore armor and we just stomped a mudhole in him in seconds. I think he got like one hit in and then we sent him into oblivion.
