This is the Dark Eldar equivalent of the pulsar, using dark matter powered lasers. Roll a dice for each point of the Phantom lance's strength when firing, with the following effects:

Dark Eldar ships armed with torpedoes may use leech torpedoes at no extra cost. These must be loaded with a specific Re-load roll, although a ship may start the scenario with them in the tubes by writing a note on the ship sheet. Leech torpedoes cause no damage other than a single, automatic critical hit. Do not roll for the effect of this critical hit, instead the leech torpedo causes a -10cm speed reduction on its target, nor may any All Ahead Full special orders may be executed by the target. Only one -10cm speed penalty applies regardless of the number attached - the effect is not cumulative. However, all leech hits on a ship must be repaired before the movement penalty is removed (e.g. if a ship suffers 5 leech hits, it remains at a reduced speed until all 5 hits have been repaired).

When not firing leeches, Dark Eldar ships equipped with torpedo tubes use the rules for Eldar torpedoes from the Battlefleet Gothic rulebook instead.

The Impaler is a specialised form of prow mounted attack craft, a little like an assault boat, but large enough to carry enough Dark Eldar assault troops to potentially overwhelm an entire ship. An Impaler is launched like an assault boat, and moves in the same way during the ordnance phase. Fighters which attack the Impaler do not automatically remove it from play, but must roll a dice. On a score of a 4 or more the Impaler is removed. Turrets may fire at the Impaler, in the same way as against ordnance, but require a 6 to hit.

When the Impaler successfully moves into contact with an enemy ship, it makes a Hit & Run attack. Roll a D6 as normal. On a score of a 1 the Impaler's boarders are defeated and the module may not be used for the remainder of the game. On a 2-6 the Impaler causes a critical hit. However, unlike assault boats, roll 2D6 and look up the score on the critical hits table (as opposed to just looking up the score of the Hit & Run attack).

If the Impaler is removed (either by turrets, enemy ordnance, attack craft and so on), the Dark Eldar vessel must reload ordnance as normal before being able to fire it again (it is assumed that a damaged module limps back to its parent vessel and must await hurried repairs or else take time for its crew to transfer to a replacement). An Impaler can only be completely destroyed by a failed Hit & Run attack, which would leave it useless by the loss of its crew.

Attack craft ordnance in a Dark Eldar fleet consists of Raptor fighters, Razorwing bombers and Slavebringer assault boats.

Raptor fighters have a speed of 30cm and need a 4+ to remain in play after removing ordnance as with Eldar fighters.

Razorwing bombers have a speed of 20cm and are hit by turrets only on a D6 roll of 6.

Slavebringer assault boats have a speed of 30cm and are hit by turrets only on a D6 roll of 6.

The Dark Eldar receive a +1 on Hit & Run attacks but may forgo rolling on the Hit & Run Critical Hit table in return for +10 Victory points. This reflects the desire of the Dark Eldar for captives, often when to do so is tactically foolish.
