sorry for the interruption, but we had a similar question with stairs and knockback in our game yesterday! Can a hero be thrown through a staircase?

This was important, because the next hit would have triggered devine retribution, so in my opinion the monsters on the other side of the staircase should be save! (i see, that this question about the retribution is discussed here too, so dont bother...)

I want to say no, because it costs a movement point to move between staircases but I could also see the answer being yes.

Figures under the effects of knockback ignore all terrain until the space they "land" on, right?

Yes, but I can't remember if stairs count as terrain. In any case I'm pretty sure the answer is no now that I think about it, but it would make for a cool move.
