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

===Contagion Discipline===

#'''Miasma of Pestilence''' - Warp Charge 6. Select a visible friendly {{W40kKeyword|DEATH GUARD}} unit within 18". Any attack that targets that unit is at -1 to hit. Note that overwatch hit rolls cannot be modified in any way, so you can't become immune to Tau shenanigans. However, this can cause overcharged plasma shots to overheat on 2s (including in Overwatch), so there's that. With Deathshroud and Blightlord Terminators, this spell will be absolutely horrifying, as it makes the unit you target not so much immune to plasma as it makes opponents shooting them with plasma <s>spontaneously combust</s> even more motivated to fire on safe mode, and thus increase your 'nators durability even further. Alternatively, throw this on one of the FW flyers that you've given a Mark of Nurgle to and laugh as your opponent pathetically attempts to take it down when they have a -2 to hit it; even dedicated anti-aircraft weapons will struggle (not true in v9 anymore).
#'''Gift of Contagion''' - Warp Charge 7. Select a visible enemy unit within 18" and debuff them with either -1 Attack, Strength, or Toughness (randomly rolled for.) Since you can't pick and choose which of these happens, this isn't as impressive as it could be. That said, if you plan on going into melee with the target unit anyway, any result is going to be useful to some extent. 
#'''Plague Wind''' - Warp Charge 5. Select an enemy unit within 18" and roll a die for each model in the unit; 6s cause mortal wounds. Effectively, this won't ever do much, but as it is one of the very, VERY few things left that scale with target unit size, you should take this if you are seeing tarpits on the other side of the table. And hey, what other Warp Charge 5 power can kill 8 Conscripts (assuming a 48-50 man blob) on average?
#'''Blades of Putrefaction''' - Warp Charge 5. Oh my, this thing. Choose a visible friendly {{W40kKeyword|DEATH GUARD}} unit within 18" and add 1 to all wound rolls it makes in the fight phase. Rolls of 7+ using melee plague weapons inflict a mortal wound. Stab that Land Raider with a rusty knife! It is probably the most synergistic power in the entire codex, since nearly every cool weapon we have is also a plague weapon.
#* Or just use the wormspitter to make it a plague weapon. Full combo, you can one shot a knight with poxwalkers now.
#'''Putrescent Vitality'''- Warp Charge 6. A visible friendly {{W40kKeyword|DEATH GUARD INFANTRY}} unit gains +1S and +1T. Unlike other buff spells, this one affects units and not models, so use it on those Poxwalkers and make them undying. (You did bring Typhus, didn't you?)
#'''Curse of the Leper'''- Warp Charge 7. If manifested, roll 7d6. The closest enemy unit within 14" takes a mortal wound for each roll that exceeds its toughness characteristic. It might not have the potential to cause more mortal wounds than Plague Wind (and won't work at all on units with T6 or higher for obvious reasons), but it's more reliable against units with lower toughness. Like, just as an arbitrary example, the ones that have been debuffed by Gift of Contagion or Mortarion's aura.  Generally speaking, only better than ''Smite'' against T3 or below; if the caster is carrying the Pandemic Staff, only better against T2 or below (after debuffs, of course).
