A Blackstone Fortress cannot go onto special orders but is assumed to automatically pass all other Leadership tests it is required to make.
The Blackstone Fortress can move up to 10 cm in any direction in the movement phase: it does not turn like a normal ship.
It has no crew and so does not add a D6 to its boarding score during a boarding action.
Super-Mega-Death Shot (not while crippled): after two turns without moving or firing it stays still and fires in the next shooting phase - trace a straight line 90 cm from its stem with the Nova Cannon template. Any ship, friend or foe, whose stem touches the template takes 8 lance shots ignoring shields and similar mechanisms; a ship whose stem touches the centre is destroyed. In Exterminatus, from the low orbit table, the planet is destroyed on a 2+. Up to three Fortresses never further apart than the template's diameter may combine the shot: each extra Fortress adds 90 cm of range and 8 lance shots. While charging, ordnance and escorts touching the area between them are destroyed; a capital ship touching it takes 8 lance shots per charging Fortress (no shields, no Brace), and each Fortress then takes D6 hits, cannot move or shoot next turn and must recharge.
