Tomb Citadel Walls

One friendly Monolith, Obelisk, Tesseract Vault or Sentry Pylon model can start the battle on top of this FORTIFICATION’s ziggurat platform. While such a model is on this platform, that model’s ranged weapons have the [HEAVY] ability. Any friendly model can be set up or end any type of move on the ramps or platform sections of this FORTIFICATION.

Each time a ranged attack is allocated to a model, if that model is not fully visible to every model in the attacking unit because of this FORTIFICATION, that model has the Benefit of Cover against that attack.

While an enemy unit is only within Engagement Range of one or more Fortifications from your army:

• That unit can still be selected as the target of ranged attacks, but each time such an attack is made, unless it is made with a Pistol, subtract 1 from the Hit roll.
• Models in that unit do not need to take Desperate Escape tests due to Falling Back while Battle-shocked, except for those that will move over enemy models when doing so.
