Ladders, doors and gates limit how many figures may pass through per turn.
How it works
If the passage is opposed, a ladder/window passes 1 figure, a door/stairs 2 and a gate/breach 3; if unopposed, the number passing is 1d6, 2d6 or 3d6 respectively. Unfinished wall passes 1 figure per inch of wall.
Some terrain features restrict the number of figures that can pass if the passage is opposed.
