Editing Warhammer 40,000/8th Edition Tactics/Death Guard (section)

===Warlord Traits===
Can be chosen freely, but if you have decision anxiety, roll a d6.

#'''''Revoltingly Resilient''''': When using Disgustingly Resilient to resist a '''''non-mortal''''' wound, add +1 to the roll. Consider having your designated sawbones (Plague Surgeon) nearby, to boost this even further.
#*Better than Constitution against 1-damage attacks, but worse against multi-damage ones. It always depends on what army you'll be facing.
#'''''Living Plague''''': Any unit within 3" of the Warlord '''''at the start of any''''' Fight phase takes a mortal wound on a 4+. Typhus comes stock with this one. 
#*Not terrifying on its own, but it allows you to dish out YET more mortal wounds, on top of Typhus' innate ability and a potential Nurgle's Rot stratagem. Works very well on death stars. Makes MSU armies wilt but won't so much as tickle a horde army. 
#'''''Tainted Regeneration''''': Recover a wound at the start of '''''each player's''''' turn.
#*Very good if fighting against jack-of-all-trades armies, but not as good as Revoltingly Resilient against armies that like to annihilate one unit at a time with focus fire (looking at you, [[Tau|weeaboos]]).
#'''''Hulking Physique''''': +1 to Toughness. 
#*Generally bad compared to Revoltingly Resilient and ''terrible'' compared to Rotten Constitution, although it can be useful on a T5 model if you're trying to wade through S3 spam, such as lasguns on a conscript-spamming list, or a T7 model such as Mamon when you’re taking on Marines.
#'''''Rotten Constitution''''': Reduce all damage taken by 1, to a minimum of 1. Less damage taken means fewer chances for Disgustingly Resilient to fail, so it's an even bigger boost than it might look. As mortal wounds are inflicted one at a time, it won’t help versus those. Compared to revoltingly resilient this trait is better vs 2d and 3d weapons, equally good vs 4d and worse against all other. If you are in range of a plague surgeon or has a maxed epidemius buff on a daemon Prince, it is virtually identical on D3 weapons as well (1.22 vs 1.25 D taken per hit), so the choice isn’t obvious. 
#'''''Arch-Contaminator''''': Re-roll all failed wound rolls made with a Plague Weapon within 7" of your Warlord. Mortarion comes with this. 
#*Blatantly the best of the bunch if you want your Warlord to be a force multiplier. Just sit a Chaos Lord (or Mortarion at that matter) with this trait on top of some Blight Launcher Plague Marines and Plagueburst Crawlers and watch the fireworks. Also makes almost every special close combat weapon (including bubotic axes which are hugely available across the codex) into lightning claws for free. In addition, does the same to blight grenades, meaning that this trait is essential for anyone planning to run a Biologis Putrifier. Add the appropriate relic to boost this to 10" and make Salamanders cry over how many more re-rolls you get than them.
**This is awful on Mortarion as he will either outrun his support units that are buffed by this ability, or get shot to hell turn 1/2 because he has more than 9 wounds, gifting your opponent Slay the Warlord and robbing said support units of this buff anyway. Never make Mortarion your warlord - always pick a Lord of Contagion or normal Termie Lord and deep strike them with some Deathshroud if you want to give your warlord this trait.
#Some of your combos become really scary only because of this gemme, grenade combos and blades of contagion combos in particular. Be mindefull of where you want your arch-contaminator to be, it will dictate a lot of you strategy.
