|Kheradruakh Codex art, doesn't he look awesome... all rights belong to Games Workshop, I do not own this picture.|
To explain why he is so very bad this is kind of going to turn into a unit review but thats alright, the lament of The Decapitator must be heard. First off his stat line.

This straight away should tell you, he is not worth 140 Points, his Strength, Weapons Skill and Attacks profiles are all pretty good but Toughness 3 and no save is concerning. Then we look at his sole piece of wargear, his sword, the Decapitator which is a Power Sword that inflicts Instant Death on a 6, useless now because most characters have 2+ Armour saves or pretty good Invul. saves.
Kheradruakh has a save though, a 5+ Invul. save which with a Toughness of 3 means he is just going to get murdered by Laspistol fire, which for the ultimate stealthy assassin in the Universe that is a living shadow, sucks. His special rules aren't very special, he has Fearless, Stealth, Move Through Cover, Fleet, Baleblast, Power from Pain, Night Vision and then his exclusive rules Shade Stalker, Hunter of Heads and Altered Physique. First rule, Shade Stalker, mean he has to start the game in reserve and can be placed anywhere on the board when he comes in and can do everything normal except assault, which is were a Quad Gun will be waiting. Hunter of Heads is dumb, choose an enemy Independent Character, The Decapitator has Preferred Enemy against him, great that'll help me when my face is being punched in by Abaddon. Altered Physique just gives him a Pain Token which gives him Feel no Pain. Also you'll notice he is a Special Character without the Independent Character rule, I though the was reserved only for the super tough like Mephiston.
Don't worry, Kheradruakh isn't the only Dark Eldar unit that suck, queue Mandrakes, ah yes, the mini Kheradruakhs that took a bat to the face when 6th ed came along, mainly due to the 'no assaulting after coming in from reserve' and 'Independent Characters without Infiltrate can't join a unit of Infiltrator even if said unit isn't Infiltrating' and this made the already hugely unpopular Mandrakes completely unusable which is a shame because the models are really good.
The final nail in the Mandrakes and Kheradruakh's coffin came from the Grey Knights FAQ, where it says they count as Daemons. Now when I read this, I was enraged by the fact that one, Mandrake are not Daemons and two, Mandrakes don't have the Daemon special rule and so they don't benefit from rules like Fear.
But that is just the way things go and I doubt we will see Kheradruakh make an appearance any time soon.
