Editing Warhammer 40,000/9th Edition Tactics/Dark Eldar (section)

=====Custom=====
*'''Dark Mirth''': Gain a 12" aura. Any time an enemy movement dares start a move inside this aura, be it walking, advancing, falling back, or charging, they suck a Mortal Wound on a 5+.
*'''Disdain for Lesser Beings''': Units with this obsession add +1 to combat attrition checks.
*'''Merciless Razorkin''': If a model with this obsession rolls a nat 6 to hit with a splinter weapon, you score another hit, equivalent to +1 BS except it stacks with being BS2+. Pairs well with Torturous Efficiency.
*'''Mobile Raiders''': Any model with this obsession that has the {{W40kKeyword|FLY}} keyword gains +2" movement. You're Dark Eldar, movement is key to your army, so this is always worth considering.
*'''Torturous Efficiency:''' If a model with this obsession rolls a nat 6 to wound with any gun, you improve the weapon's AP by 1. Aka it only triggers once every 9 shots (base), so about ''1.11 shots per 5-elf squad'', which goes up as the unit gets more accurate; more relevant for stacking with Merciless Razorkin is that it applies to 1 in 3 successful wound rolls with a Splinter Rifle or Splinter Cannon. Still, not like Merciless Razorkin can be combined with anything else, really.
**Once every 9 shots assumes BS3+, no buffs, but your accuracy can effectively be BS2+ (Trueborn or Razorkin) or BS1+ (Trueborn Razorkin) and you can apply an Archon, so that comes out to this many procs per 5 elves shooting splinter rifles:
**#Base: 1.111 (1 every 9 shots)
**#Archon: 1.296 (1 every 7.7 shots)
**#Trueborn or Razorkin: 1.389 (one every 7.2 shots)
**#Archon + (Trueborn or Razorkin): 1.620 (one every 6.2 shots)
**#Trueborn + Razorkin: 1.667 (one every 6 shots)
**#Archon + Trueborn + Razorkin: 1.944 (one every 5.1 shots)
**Toxin Crafters is better than Merciless Razorkin + Torturous Efficiency if you want to focus solely on poison guns, but Torturous Efficiency affects other guns (Shredders) and Toxin Crafters doesn't.
*'''Soulbound''': Models with this obsession gain a 5+++ against mortal wounds. Kind of not great unless you're going against Smite spam and Tau rail weapons.
*'''Twisted Hunters''': Models with this obsession get +1 to hit {{W40Kkeyword|character}}s - but Haemonculus Covens get sniper rifles, you don't, and Wych Cults are much better at melee than you are.
*'''Webway Raiders''': Whenever the Webway Portal stratagem is used on a unit with this obsession, the stratagem costs 1 CP less.  Since the strat can only be used once, this is equivalent to spending half your obsession on 1 CP.

======All-Consuming======
*'''Deadly Deceivers''': Units with this obsession can shoot after falling back, but suffer -1 to hit when doing so. This costs you two traits and is worth only 1, and hence is best avoided.
*'''Toxin Crafters''': Models with this obsession get to re-roll 1s to wound with poisoned weapons, and if they score a nat 6 to hit with a poisoned weapon, the poison value is set to 2+. Yeah, this is the one you want if you just want to go all-in with splinter weapons: because you're ws/bs3+ (the ability applies to 1 in 4 wound rolls), the net effect on Poisoned 4+ weapons (when the effect applies, it's a 5/3 multiplier on wounding) is another 7/6 multiplier that stacks with the 7/6 this comes with to wound and the 7/6 to hit an archon provides for 343/216 total (1.167, 1.361, and 1.588, respectively). Worth considering if spamming Kabalite warriors, as only the 5th, 9th, and 10th elf in a squad may wield special guns, and that 10th elf can just take a Splinter Cannon.
