Hey guys. Just wanted to post this up for Scorp and any other Imperial Fists players out there. Was just reading my Vigilus book and had a re-read of the Imperial Fists Siege Breaker Cohort... so there is a Stratagem available to them called Seismic Devastation where on Wound rolls of a 6 you cause a mortal wound in addition to normal damage in either the shooting or fight phase against Vehicles (and buildings). I was thinking of Centurions, with Storm of Fire, a Chapter Master and Lieutenant nearby that could potentially devastating, Especially when you use it concert with Hellfire Shells, or the mortal wound missile strat. Especially with heavy bolter/hurricane bolters and bolter discipline
There is also a decent warlord trait that allows you to automatically pass morale tests which is pretty good for big units, but it also grants you Cover even when you aren't in cover which again, could be great for Centurions especially on the move (if you went for Heavy Bolter/Hurricane Bolters). That warlord trait will cost you an extra CP but I figured it was worth mentioning.
Anyways just wanted to highlight that for you guys. Happy gaming!
Yes these ideas have been mentioned a few times here and there in comments. Would be good to make use of these to give my Fists a bit more 'bite' with their firepower!:)
