There were ten total on the wall. Two were up on the towers and four on each side. There is still one up on the eastern side that is entangled he has yet to make a successful strength check to break free. The three behind him went down to cross over to the other side and back up. Yes they will have to make saving throws to move through the area like everyone else. There are still four fighters on the western wall that Krusten and Ildrahil are at. Only three of them can attack though due to space. If Albrecht takes a look around yes he will be able to see the man in robes who is with some men in armor that was just hit with a fireball. Many armored men are laying around them unmoving. In fact he can see a lot of armored men laying on the ground in the court yard that are unmoving save for the shifting stones.
Yeah, those first few rolls were bad, but now there are a couple of 17s, which I think I already hit with one, a 16, and a nasty 12. Let's hope that keeps Ildrahil alive until the cavalry arrives. Let's hope it isn't the 7th Cavalry led by Custer *wink*.
