The Materialisation Rift is a thin place in reality — a cold seam in the air where the dead most easily walk out of the warp and onto the field. Place it on the board before deployment. Friendly Damned may arrive from reserve within 3" of the Rift, rather than the usual 6" from an enemy, and any Damned within 3" of it at the end of a round improves its ethereal field-save by 1 until the start of the next round. Any non-Damned fighter that ends its activation within 3" of the Rift must pass a Cool test or suffer a penalty of 1 to its Cool until it moves away — the seam gnaws at living nerves.

The Shrine of the Fallen is a memorial to the dead of the lost Chapter — a death's-head reliquary of bone and blackened ceramite that the Legion gathers around, radiating the grave-cold dread of the walking dead. Place it on the board before deployment; it is impassable terrain and grants full cover to fighters in base contact with it. Enemy fighters within 6" of the Shrine suffer a penalty of 1 to Cool and Willpower. Once per battle, when a friendly Damned within 3" of the Shrine is taken Out of Action, it may be set back up in base contact with the Shrine on a single Wound — the fallen returning to the memorial of the fallen.
