Scanned the forum but did not find anything on this topic (granted i am not the most observant).
Can a Deamonsmith use his infernal engineer ability on a Hellcannon which is classed as a monster rather than a war machine.
Anyway, this issue came up in my last game after i decided to try to use the ability on a hellcannon and we decided that he can only use it on war machines.
Our reasoning was the Hellcannon is a monster, though it may fire as a war machine it is not one by rights of its 8th edition unit profile, thus an deamonsmith would not be allowed to re-roll any dice for it.
Just wondering if any one else has run into this issue and if so how did you handle it. I have been deliberating and have come to the conclusion that we were correct in our ruling, but would like to know how more experienced players have dealt with the issue.
