I rigged the first Archer miss because if Roy gets hit too much he will die. Bors's miss and the second Archer miss were coincidence. I think the movements are straightforward enough otherwise.

I doubt turns can be feasibly removed since even if I were to rig it so Roy crits Bors multiple times(Roy doubles Bors and deals 3 damage with his Rapier), he cannot reach Bors in less than 6 turns so this wouldn't actually save any.
