Editing Warhammer 40,000/7th Edition Tactics/Renegades and Heretics (section)

=====The Purge===== 
No fast attack slots whatsoever, but you get 8 Troops slots, six Elites, and 4 Heavy. The only compulsory slots are 1 HQ and 2 Elites. The other restriction is that no unit may have a Mark/Covenant with any god other than Nurgle. The bonus for using this detachment is that any barrage weapons you fire leave the markers in place, and count as dangerous terrain until your next turn. Also any flamer weapons or frag missiles in the army may get the ''Shred & Gets Hot'' rules for free.
*Combo with an Ordnance Tyrant to make your Artillery units into Elites & Troops choices (as well as staying in Heavy) and "literally" carpet the entire board with templates, you're better off using circular paper cut-outs considering the large quantity of templates you can throw out and can lay them carefully over the top of opponents models without damaging them or be flat on the tabletop for them to walk over.
*Despite it saying that the Purge detachment can include units from Chaos Renegades or Chaos Space Marines, ''you don't get both in the same detachment, and have to choose one or the other. [http://www.dakkadakka.com/dakkaforum/posts/list/150/635452.page#7661580| (see here)], otherwise that could open the ENTIRE selection of unaligned & nurgle units (except Fast) to each other.'' (I might look into this further, i'm not seeing evidence, and forgeworld has not released a formal FAQ that i am aware of to resolve this.)
*Running it with CSM is harder, but you can spam Decimators, Hellbrutes, and Achilles, and not go far wrong. Wedging in a bare-bones Cyclopia Cabal can help in this regard, netting you more Infernal Relic unlocks.
*Also, a Fortress of Redemption goes well with this Detachment, adding cover and armor suppression to your anti-infantry game.
*If not using this detachment as your primary, you can basically view this as allied detachment plus as it lets you take elites and heavy support with no troops and stay battleforged - need some anti-horde? 2 Squads of Chosen w/ shredding chemical flamers! Need some Psykers? Take a Rogue Psyker demagogue along with extra psykers who are now elites instead of HQs!
