Hello everybody!
The Chaos Lord is a very important force multiplier to any
CSM army. Not only do they do some
FOC switching around, they are often a key offensive element. Here's my take on how to load out the ubiquitos Chaos Lord.
Note that there are TONS of useless options that you can pile on a Chaos Lord, and for convenience I won't even mention them.
General things:
VotLW: This is a near-mandatory upgrade. If you are taking a Daemon Weapon, you should ALWAYS take this. Those rerolls on the first turn can save your bacon if you roll a 1 for your daemon weapon.
You should always give your Lord an invul save by any means necessary. Unless you are taking Terminator armor (I will explain below) you should always take a Sigil of Corruption, or unless you are going for a cheapo build.
A gift of mutation is never a *bad* choice, but it is so unpredictable to the point where it should only be used if you have the points to spare.
First off, you need to be efficient when loading out a Chaos Lord. From my experience, a Chaos Lord should never hit 200 points. There are multiple upgrades that are counter-productive as far as efficiency goes.
Here are the main offenders

:
Putting a
SoC on a Terminator Lord
Giving a Terminator Lord a Daemon Weapon
The Terminator Lord
A Terminator Lord is paying a Cultist squad minus 10 points for terminator armor, and there's a reason it is more expensive than the Sorceror's Terminator armor. The reason being is that the cost of a power weapon is already factored in. Therefore, if you additionally throw on a Daemon weapon, you are basically throwing away the free cost of a power weapon (unless you plan on taking both for the extra attack, but that's pretty redundant).
Also, although it is tempting to give your Lord a 4++ for an extra Cultists squad minus 25 points, it is really not worth it (unless you are running a Tzeentch Lord, but in that case you're probably better off ditching the Termi armor).
If you are running a Terminator Lord, your best bet is to either keep him with a regular power weapon or give him the
PF +
LC combo.
Sample build: Nurgle Terminator Lord:
PF +
LC,
VotLW' = A Thunderfire cannon + 52 points
Nurgle Terminator Lord: Power Axe/Maul,
VotLW= A Thunderfire cannon + 25 points
These are both very cheap
HQs that should dominate most things in
CC.
The Cheapo Lord and the Power Armor Lord
Even though the Terminator Lord is pretty cheap already, you can build a budget Lord if all you are concerned with is doing some
FOC changes, or just filling your mandatory
HQ slot.
In this case, the Burning Brand of Scalathrax can be useful if you want your Lord to just sit back and cover your backfield.
If you plan on your Lord sitting back and avoiding the fight, you can probably get away with not giving him a
SoC. However, I don't like using units who just sit there doing nothing, but it's your call.
If you want, you can also build a cheap Lord who acts as a Daemon weapon carrier. These are usually only useful in transports, or in a giant blob of cultists. In my opinon they are more effective than Terminator Lords, plus they can sweeping advance.
Sample builds: Nurgle Lord with Burning Brand and
SoC = Thunderfire cannon + 35 points
Nurgle Lord with Burning Brand = Thunderfire cannon + 10 points
Khorne Lord with
SoC, AoBF,
VotLW = Thunderfire cannon + 35 points
Nurgle Lord with
SoC, Black Mace,
VotLW = Thunderfire cannon +45 points
The Biker/Steed Lord
These are by far the most fun Lords to run in my opinion. I have found that running them with spawn is always better than bikes, but that is an analysis for a different day.
I only really have experience with the Khorne and Nurgle builds, and will use those examples.
As far as the Khorne Lord is concerned, ALWAYS take the juggernaut instead of a bike! For an extra 15 points you are getting +1 attack, strength, and wounds over the bike option. Plus you are cavalry and therefore have fleet. It is a bargain
IMO.
With an AoBF, this guy has 8-13 S7 AP2 attacks on the charge in addition to his S5
HoW. He can nuke almost anything on the charge.
Sample build: Khorne Lord with
SoC, AoBF,
VotLW, Juggernaut = Thunderfire cannon + 75 points
With a Nurgle Lord, I used to be torn between the
PF +
LC combo or The Black Mace. After testing them both, I can wholeheartedly say The Black Mace will always be the better choice (plus it looks a lot better modelwise).
Unfortunately the Palanquin of Nurgle is crap, so always take the bike. T6 is the biggest toughness threshold in the game, and helps A LOT.
Here is how I prefer to run him: Nurgle Lord with
SoC, TBM,
VotLW, Bike, blight grenades (helps a lot when running spawn, as giving a cover save within 8" is pure gravy when your spawn have no save) = Thunderfire cannon + 80 points
I obviously didn't cover everything, so feel free to give input!
