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

===Nurgle Daemonkin===
Mortarion and the Daemon Engines have the '''NURGLE''' and '''DAEMON''' keywords, allowing them to benefit from the buffs of Poxbringers and Epidemius' Tally of Pestilence. With this, Mortarion can be buffed to an S9 T8 21 Attacks monster, and that's without any psyker shenanigans! You can also get S8 Plaguespitters on your Bloat Drones in case you wanted anti-tank flamers. Blades of Putrefaction and Virulent Blessing can also make a nasty combo if applied to Mortarion or a Fleshmower Bloat Drone, and Fleshy Abundance is always useful. Since you can organize an army around the '''NURGLE''' keyword, you can have an Outrider Detachment based on Bloat-Drones and Blight-Haulers (who won't mourn for the loss of Inexorable Advance seeing as they never benefited from it) lead by Epidemius and/or a Poxbringer. Horticulus Slimux can help out further by providing healing (via Cultists dying near him) and planting Feculent Gnarlmaws which provide cover (For infantry), more buffs(Charging after Advancing/Falling Back), aid in summoning, and mortal wounds to non-Nurgle things all at the same time.
* Seriously, never overlook the Gnarlmaws.  They're a pain in the ass piece of terrain for your opponents.  Also, as noted, Mortarion is a Nurgle Daemon so Gnarlmaws will let him charge after advancing.  If you can figure out how to buff him with Warptime, he'll be in your opponent's lines and melting face faaaar quicker than they likely anticipated with an average total movement of 34" at full health. Even if you're not running a Daemon Detachment, consider a Fortification Network for these nasty trees.
* Another way to use Nurgle Daemons is to get a Supreme Command Detachment and fill out the rest with Nurgle '''Chaos Daemons''' ''not'' Death Guard ones. Locus of Virulence will cause any wound rolls of 6 for your Daemon Engines to deal 1 additional damage if they're near a character from this detachment.
* Yet another alternative is to rely on summoning: with Plague Pact (CP 1) summoning most of these are trivial, since 4d6 has an average roll of 14 - which lets you summons basically *any* creature from Codex: Chaos Daemons, including all these mentioned above. Epidemius himself has such a low PR that 2d6 is already reliable enough. Just remember to keep points in reserve - which you might want to do anyway if you're using Typhus and Poxwalkers.
