In a game last night, I had a unit of Chaos Warriors in the watchtower. My opponent charged with High Elves. The rules for buildings say that we get ten models per side fighting. His Hero cut my Champion down in a challenge, while his Swordmasters killed about another three.
How many of my models get to attack back? The rules are clear that, despite suffering casualties, other models will 'step up' to take their place - so the three casualties didn't matter, but what we weren't clear on was the effect of the challenge. Since only the Champion can fight in that, and he is now dead, does this mean that only nine of my rank and file models can attack? Or do I still get ten models' worth of attacks on the rank and file of his unit (i.e. can someone still step up to replace the Champion in my ten models)?
