I've had the unit ages, but I only just used his fell call 'Rage Howler' for the first time yesterday. Ended up with a fleeing unit of Daughters of the Flame, a fleeing Choir and a fleeing Vassal, the -2 to jacks also meant the Crusader and Castigator (now minus Choir support) couldn't land attacks on my Mangler. It's a good day when most of Menoths support just turn tail and run off. I know this isn't going to happen everytime, in fact if it ever gets that good again I'll be shocked. It was just one of them jaw dropping moments that really change the course of the game.
So, anything like this happened to you? Any good war stories that really make you want to give a little bonus pay to the unit after.
