• There's a whole bunch of new siege equipment.
  • I've expanded the rules for walls and gates to allow more units to simultaneously assault and garrison them as we found that the attacking army often had units standing around because all walls were already being assaulted.
  • Same goes for towers, but you need special siege equipment to assault them from ground level now (they're higher than walls after all).
  • I've also added some benefits for ethereal units and flying that assault the fortress. They're mostly flavour (it "makes sense" but it might not be balanced).
  • I expanded the rules for breached sections so they provide less cover due to the damage.
