ALBE=Autarch Lasblaster equivalent

Army-wide special rules:
Night Vision - Acute Senses USR

Strength Through Pain – Most standard Dark Eldar Infantry units will have this rule, although some of the more out there ones will not. The unit (and only the unit) gains an upgrade every time it wipes out an enemy unit (3 max). 1st Feel No Pain, 2nd Furious Charge, 3rd Fearless.

If an IC or IC's join a unit then their cumulative pain points are added together and they gain the benefit of all of them combined. Should the IC leave the unit, the pain points must be distributed as evenly as possible with any remainder being left to the owning player's discretion. If multiple enemy units are destroyed in a combat against multiple DE units, then all the pain points are randomly assigned to the victorious DE side, they don't EACH get a point for every unit destroyed by the combat's results.

Combat Drugs - Succubus (no drugs for Lelith), Wyches, Reavers, Hellions, option for Archons
Roll once. All units with the Combat Drugs rule get the same benefit. One result confers a free pain point.
Results are:
3D6 pick the highest Run moves
+1 S
+1 WS
+1 A
reroll to wound rolls in close combat
+1 free Pain Token

12" Assault and "always attacker" results are gone.

Weapons:

Dark Lance: S8 AP 2 Heavy 1, Lance (even for Scourges)

Splinter Rifle 24" SX, AP5, Rapid Fire, Poisoned.

Shard Carbine 18" SX, AP5, Assault 3, Poisoned.

Splinter Cannon 36" SX, AP5, Assault 4, or Heavy 6 Poisoned.

Splinter Pods - 18" S X AP5 Assault 2, Poisoned

Blaster - 18” S 8 AP2 Assault 1, Lance

Disintegrator – S5 AP2 Heavy 3

Shredder - still in

Heat Lances - 18" S6 AP1 Lance, Melta

Wargear:

Webway Portal:
archons, haemonculi only
dropped in shooting phase, dropping the portal counts as shooting and the person who drops it CANNOT be in a vehicle when he drops it. It then acts like a board edge that you can bring reserves on. The WWP is indestructible and impassable once it's down...and in a change, cannot be used to bring on vehicles. Also, if you have a WWP you can always put things in reserves even if the mission doesn't allow. Outflanking and deepstriking reserves can use the portal.

Agonizer: power weapon, no poison rule, but wounds always on 4+

Djinn blade: is not a weapon, but gives 2 additional power weapon attacks, rolled separately, on doubles hits wielder instead

Plasma Grenades: wyches have acces to them, warrior can buy them

Orgasm Grenade Launcher: whole unit has offensive and defensive grenades

Soultrap: If bearer kills an enemy MC or SC in close combat he doubles his Strength to 6. If he kills another one, he doubles his Strength to 10.

Clone Field: is a wargear item which allows the bearer to nullify D3 attacks directed at him each turn; the specific attacks are chosen by the bearer. Mutually exclusive with shadow field

Shadow Field: same as before

Huskblade: Power weapon that causes Instant Death.

Drug Dispenser: access to combat drugs

Hexfire Rifle - Sniper Rifle, wounded model takes a wounds test or is removed from play (yes this does circumvent EW)

Blast Pistol - 6" range Blaster, counts as CCW.

Mindphase Gauntlet: any IC or MC HIT (not neccessarily wounded) by this weapon must take BOTH a Strength and a Leadership test for EACH hit. If ANY of these tests is failed, that IC or MC may not attack this assault phase. NO power weapon,

Special Characters:
There are 8 special characters, all are HQ choices:

Asdrubal Vect
Can be taken mounted or on foot. It has been said his throne fits nicely in the spot where the sail goes on the new Raider kit. This implies no new model. Personally, I think the new kit would look a little silly without the sail.
Seizes the initiative on a 4+
has preferred enemy against all unit types and re-rolls to wound against all Eldar models (including Dark Eldar)
Armed with Obsidian Orb: S10 AP3 Assault 1 Blast Weapon that rolls against the target's Ld stat rather than their T. Any unsaved wound caused heals Vect up to his starting number of wounds.
Dais: optional, 200 albes, 13/13/13 raider, transport 10, 3 dark lances
vect and 9 other passangers MUST be deployed in the dais at the start of the game

Duke Sliscus
A corsair captain described as a nasty counterpart to Yriel.
Gives you 2 rolls on the combat drugs chart, picking the result you want.
2+ poison weapons, if he rolls a 5+ to wound, they also ignore armour. A single unit of either warriors or kabalite trueborn have their poison weapons upgraded to 3+.

Apparently there's a strong indication that Drazhar is actually Arhra.
