You’ve seen the box art. You know the drill: chainaxes, chainswords, and more chain-related weaponry than a hardware store gone rogue. But there’s a specific niche in the XII Legion—the World Eaters—that feels almost like a throwback to a more elegant, albeit much bloodier, era of the Great Crusade. I'm talking about World Eaters with lightning claws. It’s a loadout that honestly gets overlooked because everyone is so obsessed with the "chainax-go-brrr" meta, but if you actually look at the math and the lore, there’s something terrifyingly efficient about a Berzerker or a Chaos Lord coming at you with ten energized blades instead of a spinning motor.
Blood for the Blood God. It’s a simple mantra.
In the current state of Warhammer 40,000, specifically with the 10th Edition codex and the way the World Eaters army functions, you’re looking at a force that thrives on the "Blessings of Khorne" mechanic. Lightning claws have historically been the red-headed stepchild of the Chaos Space Marine armory for the XIIth, mostly because the faction has such a hard-on for strength modifiers and AP (Armor Penetration) that come with their signature axes. However, a pair of lightning claws offers something those axes often lack: reliability through volume and the Twin-linked keyword.
The Reality of World Eaters with Lightning Claws on the Tabletop
Let's get into the weeds. Why would you actually run this? Honestly, most players won't. They’ll stick to Eightbound or standard Berzerkers. But if you’re kitbashing or looking at Horus Heresy-era models to use in 40k, the lightning claw becomes a fascinating tactical choice.
Twin-linked is the secret sauce here.
In 10th Edition, "Twin-linked" allows you to reroll the Wound roll. For a Legion that already gets bonuses to Strength on the charge (thanks to the Relentless Rage army rule), hitting a Strength 5 or 6 threshold is common. When you’re wounding most infantry on 3s or 2s and you get to reroll every single failure, the mathematical "chip damage" turns into a total wipeout. You aren't fishing for big hits; you're ensuring that nothing survives the sheer volume of cuts. It's death by a thousand energized needles.
It’s also about the aesthetic of the "Red Butchers." If you look back at the lore—and specifically the Betrayal books from Forge World—the World Eaters used lightning claws to devastating effect during the Shadow Crusade. There’s something specifically "XII Legion" about the visual of a Cataphractii-armored Terminator just walking through bolter fire to literally pull a Loyalist apart with his hands.
Building the Narrative: More Than Just Axes
The World Eaters weren't always just mindless drones. Before the Nails really took over, they were the "War Hounds." They were disciplined. Even after Angron took command and the Butcher's Nails became mandatory, different companies maintained different combat preferences. Lightning claws were often favored by the assault specialists who found axes too clumsy for close-quarters boarding actions. Imagine being stuck in a cramped hallway on a cruiser. An axe needs a swing arc. A lightning claw just needs a thrust.
Basically, it's more personal.
If you're building a 40k army, you might find your Chaos Lord or Exalted Hero of Chaos (if you're running them as a proxy) benefits from that high-volume output. You lose the "Dmg 2" or "Dmg 3" of some heavy weapons, but you gain a level of consistency that is rare in a dice-heavy game. You’ve probably had those games where you charge a unit of Intercessors, roll a handful of 1s and 2s to wound, and watch your expensive World Eaters get slapped back. With lightning claws, those 1s and 2s get picked back up.
The Kitbash Problem and the Rule of Cool
We have to talk about the models. The current World Eaters Berzerker kit doesn't actually come with lightning claws. This is a tragedy, frankly. To get World Eaters with lightning claws, you’re usually looking at poaching bits from the Warp Talons box or the standard Chaos Space Marine Terminators.
It’s worth the effort.
There is a specific joy in seeing a World Eater model that deviates from the "bunny ears" helmet and chainax combo. Using the claws from the Horus Heresy MkIII or MkVI kits gives them a scavenged, "Long War" veteran look. It tells a story. It says this guy has been killing people since the Siege of Terra and hasn't bothered to change his gear because, well, it works.
- Buy a box of Eightbound.
- Realize the claws are cool but maybe not "classic" enough.
- Source some Tartaros Terminator claws.
- Profit (in skulls).
Competitive Viability: A Nuanced Take
Let’s be real for a second. If you’re going to a Grand Tournament (GT), you’re probably taking Lord Invocatus and as many Eightbound as you can fit in a Land Raider. In that hyper-competitive environment, the "Accursed Weapon" profile has largely swallowed up the unique identity of the lightning claw for standard infantry.
But for the Chaos Terminator Squad in a World Eaters detachment, you still have choices. Paired lightning claws on a block of ten Terminators coming out of Deep Strike? That’s a nightmare for an opponent’s backline. You're putting out an absurd number of attacks. When you factor in the +1 Attack and +1 Strength on the charge from the World Eaters' faction rules, those claws are suddenly hitting at a profile that can threaten light tanks, not just infantry.
Most people get this wrong. They think World Eaters are only about Strength 10 hits. They forget that 40 attacks at Strength 6 with full wound rerolls will kill almost anything in the game through sheer attrition.
The Psychological Factor
There’s also the "fear" element. Seeing a unit of lightning claw-equipped madmen across the table changes how an opponent plays. They know their invulnerable saves will eventually fail. They know their high Toughness won't save them because of those rerolls. It forces them to screen differently. It forces them to waste shots on a unit that might not be the "optimal" threat but is definitely the scariest one visually.

How to Actually Play Them in 10th Edition
If you're going to commit to this, you need to lean into the synergies. Don't just throw them forward and hope for the best. You want to be looking at your Blood Tithe—excuse me, Blessings of Khorne—rolls every turn.
- Total Carnage: If you can trigger the 6+ Feel No Pain or the movement buffs, your claw-wielders get into range faster.
- Sustained Hits: Rolling a 6 to hit and getting an extra hit is great. Rolling a 6 to hit and getting an extra hit that you then get to reroll the wound for? That's the sweet spot.
Honestly, the best way to run World Eaters with lightning claws is as a vanguard unit. They are your "chaff clearers." While your Khârn the Betrayer or your Angron is busy hunting the big stuff, the claw unit is there to make sure you don't get bogged down by 20 Imperial Guard Conscripts or a swarm of Gaunts. You don't want your expensive chainaxe units wasting their high-damage swings on 1-wound models. The claws are the surgical tool for the mass-clearing.
What Most People Get Wrong About the XIIth
The biggest misconception is that the World Eaters are "tactically simple." People think you just push everything forward and roll dice. While that's mostly true, the nuance comes in the equipment. Choosing lightning claws is a declaration of intent. It shows you understand the math of the game. It shows you know that sometimes, "More" is better than "Harder."
If you look at the legendary "Red Butchers" (the World Eaters' specialized Terminator elite), their lore is defined by being so lost to the Nails they have to be chained up between battles. When they are unleashed, they don't use delicate tactics. They use their claws to rip through power armor like it’s parchment. If you're a fan of the fluff, you owe it to yourself to have at least one unit that represents this absolute savagery.
Actionable Steps for the Aspiring Conqueror
If you’re sold on the idea of adding some clawed carnage to your warband, don’t just buy a box and hope. Start by looking at the Horus Heresy range for your base models; the scale is slightly different, but the "relic" feel is perfect for 40k.
Next, focus your painting on the transition between the power cables and the blades. Lightning claws look best when they actually look energized. Use a bright blue or a startling white-green to contrast against the deep Khorne Red of the armor. It draws the eye to the weapon, which is exactly what you want on the tabletop.
Finally, practice your target priority. Know which units in your opponent's army rely on "Toughness over Wounds." Those are your targets. A Gravis-armored Captain might think he’s safe because he’s Toughness 6, but he isn't ready for 6-8 lightning claw attacks hitting him with rerolls.
Stop worrying about what's "top tier" on some meta-ranking website for five minutes. Go get some claws, glue them onto some angry red Space Marines, and start harvesting. The Blood God doesn't care if the wound came from an axe or a claw, as long as the blood flows.
Next Steps for Your Warband:
- Audit your current list: Identify where you are over-killing small units with high-damage weapons and consider replacing that unit with a high-volume claw alternative.
- Kitbash Check: Source lightning claw bits from the Warp Talons or Tartaros Terminators kits to ensure your World Eaters look distinct from standard Chaos Marines.
- Math-Hammer: Run a quick simulation of 20 chainaxe attacks versus 20 twin-linked lightning claw attacks against a Toughness 5 target; the results will likely surprise you.
