At the start of each of your turns, roll 2D6 and add the current turn number. This is the range of the reliquary's dark aura this turn in inches. All enemy units within range of the dark aura immediately take D6 hits, with a Strength equal to the current turn number, distributed as from shooting. Also, place a marker next to all friendly Undead units that were within range of the dark aura at the start of the turn. These units improve their Regeneration saves by one point until the start of their next turn, to a maximum of 4+. If they have no Regeneration save, they are treated as having the Regeneration (6+) special rule instead. Finally, if the 2D6 result was a double, then in addition to the usual effects, the Mortis Engine takes 1 Wound with no saves of any kind allowed. When the Mortis Engine suffers its last unsaved Wound, every unit within 12 plus the turn number in inches, friend or foe, must take 2D6 hits with a Strength equal to the current turn number. These hits are distributed as shooting.
