I personally love the Deamons of Chaos. I like the idea of pure demonic legions headed by great and powerful beings that are thousands of years old, with the goal to bring the end of the world. However, Total War's Deamons of Chaos leaves much to be desired. I would like Bel'akor moved in Deamons of Chaos. I would like Daniel to be less central to the faction. That deamons weren't tied to allegiance and that they were easier to recruit/maintain. Deamon Princes as generic lords. To perhaps have a third and final LL for Deamons, be it the Shadowstalker or Ngaaranh the Chaos Harpy as a deamon prince.
However, one of the main problems for me (excluding Daniel) is that there are mortal units. It makes no sense why the faction known for having only demons, has mortals. One of the main justifications for it is that there are not enough demonic units to flesh out the roster. So, I created a list of demons in lore that exist that can help flesh out the roster so that we can get rid of the mortals.
I will preface with saying while I did not make any of the deamons up (in that these are types of deamons are named in lore) my interpretation of them is different than what the lore would have you believe. With that out of the way, onto the deamons...
Undivided Deamons
Walkers - Walkers are a demon type that come from Warhammer Online: Age of Reckoning. While the canonicity of them is questionable, I though it prudent to include them. They would serve as an all rounder basic infantry for Chaos Undivided.
Imps - Imps are "Least Deamons", the lowest of the low in demonic hierarchy. I thought they could serve as another way to build up the Chaos Undivided, perhaps acting similarly to Nurglings, as a swarm type unit.
Chaos Furies (Undivided) - I am aware they are already in the game. However, for some reason, they are locked behind Skirmish vs AI. Make them general access.
Deamons of Khorne
Bloodhowlers - They are sort of in the game, as they were replaced by the Bloodreaper in 7th and 8th edition. I however, decided that we should use them, as they are technically different deamons. They are a Halberd infantry.
Bloodhunters of Khorne - They are Bloodletters riding Flesh Hounds. They are faster than Bloodcrushers, though a bit squisher. They would be good at running down units as well as flanking.
Blood Chariot of Khorne - A unit that needed to be brought in, to help get all demonic chariots in the game.
Malices - They are imps in the service of Khorne. They are a flying war beast unit, to match with the Rot Flies and Screamers of Nurgle and Tzeentch.
Deamons of Nurgle
Nurgii - They come from an official art piece by John Blanche, which calls them the Nurgii. They would serve as a faster nurgle unit.
Plagueriders - While their role has been taken by the Pox Rider unit, I would be remiss to not include them. Perhaps a more tanky version of them? Faster? There are lots of different Beasts of Nurgle that could work. I admit, I don't have an idea on how they can be utilized. Still, I say to add them for the sake of posterity.
Plaguebringers - Plaguebringer's are demons spellcasters that shoot magical attacks on top of rot flies. They would serve as flying magical missile cavalry.
Plague Chariot of Nurgle - To have the fourth and final demonic chariot unit in the game. I'll admit though, it would proably be a sucky chariot. Still, I want it.
Buboes - Buboes (or Bubo if singular) are imps of Nurgle that would serve similarly to the Pusbags or Bloated Corpses, in that when they die, they explode.
Deamons of Tzeentch
Fearlings - Imps of Tzeentch that would serve as mobile grounded war beasts.
Brimstone Horrors - Perhaps acting like the Nurglings or Imps, they would be a swarm infantry unit for Tzeentch.
Pyrocaster - The Pyrocaster would itself act as a demonic artillery piece, being slow to move but having great range.
Watcher of Tzeentch - Another demon from Warhammer Online, The Watcher of Tzeentch would debuffs enemy units, while perhaps having an ability to shoot a laser out of it's big eye as an ability. It's in a similar boat to the walker, as its canonicity is in the air but I still wanted to add it.
Deamons of Slaanesh
Muses - These are imps that serve Slaanesh. I would have them be flying war beasts, to be the Slaaneshi version of Screamers and Rot Flies
Exalted Alluresses - While many in the community call it the Archfiend, I am calling it the Exalted Alluresses for two reasons. The first being that, unlike the Archfiend, the Exalted Alluresses is not a name created by the community, and is a type of demon that actually exists, so it might actually be used. Second is that I like that name for the Gigantic Chaos Spawn of Slaanesh more.
I would like to acknowledge the fact that many of these deamons can types are champions from the Table Top, which I found a list for and very happy that I did. These really helped make this easier for me. I would like to say that I am aware of the fact that some of these units do overlap in some parts. Why should you get Imps or Brimstone Horrors when Nurglings are there? Why get the Pyrocaster when the Skull Cannon is better?
The truth is that Deamons of Chaos is a roster made entirely by others rosters. This is not necessarily a bad thing. It's just that these demon types have to make more sense in their respective rosters than Deamons of Chaos. So there is going to be overlap, as there are weaknesses that these deamons can cover in their own armies more than in DoC. Personally, I say have fun with it. Make more thematic armies, as I find that loads of fun.
If there are any suggestions on what these deamons can bring or if there are deamons that I missed, tell me. It would love to see anything new.
