Who are the Ossiarch Bonereapers?
Imagine an undead army that files its paperwork. Where the Nighthaunt are a screaming, ragged ghost-tide, the Ossiarch Bonereapers are cold military order made flesh — or rather, made bone. These are Nagash's elite legions, built to specification from the harvested skeletons of the dead (the grim bone-tithe) and forged by master Mortisans into disciplined, unshakable constructs. They are the sharpest, most controlled army in the Grand Alliance Death range, and a brilliant pick if you want an elite force that hits hard and simply refuses to break.
The Core Fantasy
You are not commanding a horde. You are commanding a machine. Every construct in your army was purpose-built by Nagash's necromancers to do a job, and it will do that job with terrifying, emotionless precision. The Bonereapers do not rout, they do not panic, and they do not care how many of them you break — they simply hold the line and grind you into the dirt. This is the fantasy of the disciplined, unbreakable elite: fewer models, better models, and a general (the peerless Orpheon Katakros) who treats the battlefield like a chess problem he has already solved.
Expect:
- Low-to-mid model count: an elite army, so a full force is fewer miniatures than a horde faction.
- Serious durability: tough constructs that shrug off hits and hold objectives all game.
- Discipline and command: unit-boosting mechanics that reward ordered, deliberate play.
- A striking, clean look: bone and ivory with teal or dark-metal accents — instantly recognisable.
- A cerebral general's army: position matters, and good play is rewarded richly.
How They Play on the Tabletop
The Bonereapers are a control army. You will rarely have the most models on the board, but the ones you have are dense, durable, and hard to shift once they plant their feet on an objective. Mortek Guard soak up punishment, your heroes buff and heal your line, and your elites and artillery punch holes where it counts. The whole army pivots on a resource-and-command economy that rewards you for playing tidily and thinking a turn ahead — this is not a plonk-it-down-and-charge faction.
What you'll love:
- They just won't die: tough battleline plus healing means your line stays intact when other armies have crumbled.
- Fearless to a fault: discipline mechanics make morale and battle-shock a non-issue — you never lose models to panic.
- Fewer models to paint and carry: an elite force is kinder on your wallet, your paint time, and your carry case.
- Rewards skill: smart positioning and command use turns a good list into a brutal one.
What can bite you:
- Low model count cuts both ways: lose a key unit and you feel it — there is no endless tide to replace it.
- Not a beginner's autopilot: the command and resource mechanics take a few games to click.
- Board control over raw speed: they grind rather than blitz, so fast objective-grabbers can pressure you.
- Elite pricing: more expensive models per point of force than a cheap horde.
Order Against the Ghost-Tide
Death has two very different faces, and the Bonereapers are the tidy one. Where the Nighthaunt are grief and vengeance made into a chaotic, wailing storm of ghosts, the Ossiarch Bonereapers are Nagash imposing order on death itself. Everything about them is deliberate: the ranked phalanxes, the identical bleached-bone armour, the cold logic of Katakros directing the slaughter like a spreadsheet with a scythe. If the Nighthaunt are the nightmare, the Bonereapers are the bureaucracy that decides who dies next.
That contrast is a big part of the appeal. Two armies from the same Grand Alliance that could not feel more different to collect, paint or play — the ragged ghost-tide versus the disciplined bone legion. Plenty of Death collectors end up owning both.
Key Unit Roles (What You'll Commonly Need)
1) The Anvil (Mortek Guard): your disciplined battleline. Ranked skeletal legionnaires with spear or blade who hold objectives, weather charges, and refuse to break. Every Bonereapers force is built around a solid block of these.
2) The Support Heroes (Mortisan Boneshaper, Soulmason, Soulreaper): the Mortisans who heal your constructs, buff your line, and keep the army's command economy ticking. The Boneshaper in particular knits your Mortek back together mid-fight.
3) The Hammer (Necropolis Stalkers, Morghast, Kavalos Deathriders): your damage-dealers and hitting power. Stalkers are versatile elite killers, Morghast are heavy hitters, and Deathriders bring speed and a charge that actually hurts.
4) The Bodyguard (Immortis Guard): elite constructs that screen your warlord and hold the centre. Tough, dangerous, and the perfect babysitter for Katakros.
5) The Firepower (Mortek Crawler, Gothizzar Harvester): the Crawler is your bone-flinging artillery for softening enemy blocks at range, while the Harvester lumbers about reaping the fallen and topping your force back up.
Getting Started the Smart Way
Step 1 — Start with a battleline core.
- A solid block of Mortek Guard is the backbone of any list — get comfortable ranking and painting them first.
- Batch-paint them together; the bone recipe is quick and they reward assembly-line hobbying.
Step 2 — Add a Mortisan hero.
- A Boneshaper or Soulmason gives you the healing and buffs that make your line feel unkillable.
- One characterful centrepiece hero is far more fun to paint than yet another rank of infantry.
Step 3 — Bring some punch.
- Round the force out with a hammer unit — Necropolis Stalkers or Kavalos Deathriders — so you can actually take objectives, not just hold them.
- A Mortek Crawler adds ranged threat and changes how opponents approach you.
Step 4 — Learn the paint scheme early.
- Nail your bone recipe on one test model before committing to a unit — see our beginner painting guide to get the basics down.
- The Warhammer Colour paints range makes the classic bone-over-the-whole-model, wash, drybrush approach genuinely fast.
Common Beginner Mistakes (Avoid These)
- Playing them like a horde: you don't have bodies to throw away — every unit matters, so protect your line.
- Ignoring the command mechanics: the Bonereapers' discipline economy is where the army's power lives; learn it, don't neglect it.
- Skipping the Mortisans: without your support heroes healing and buffing, your durable line becomes merely tough instead of unkillable.
- Overcomplicating the paint: bone is meant to be a fast contrast-and-wash job — don't fight it with fiddly layering on rank-and-file.
- No hammer: an all-anvil list holds forever but never wins — bring something that kills.
Who the Ossiarch Bonereapers Are For
“Choose the Bonereapers if you want an elite, low-model-count army that is fiendishly hard to kill, rewards clever positioning, and looks stunning in ranked bone-and-teal. Give them a miss if you crave a swarming horde, a blitzing alpha-strike, or an army you can play on autopilot.”
Frequently Asked Questions
Are Ossiarch Bonereapers good for beginners?
They are a fantastic collecting starter because the elite, low model count means fewer miniatures to buy and paint, and the bone scheme batch-paints quickly. On the tabletop they ask a bit more of you — the command and healing mechanics take a few games to master — but they are very forgiving once they click, since they rarely lose models to panic.
How many models do I need for an Ossiarch Bonereapers army?
Fewer than most factions. As an elite army, a full force is built around a durable core of Mortek Guard, a couple of Mortisan heroes, a hammer unit and some support or artillery — far fewer models than a horde army needs to field the same size of force.
What colours are Ossiarch Bonereapers painted?
The classic scheme is clean bone or ivory across the whole model with teal or dark-metal accents. A contrast bone basecoat over the entire miniature, a wash into the recesses and a light drybrush gets you a striking, tabletop-ready result fast — ideal for batch painting a ranked army.
Who leads the Ossiarch Bonereapers?
Orpheon Katakros, Mortarch of the Necropolis — a genius undead general who commands the legions on Nagash's behalf. Other notable heroes include Arch-Kavalos Zandtos and the Mortisans (Boneshaper, Soulmason and Soulreaper) who forge and sustain the constructs.
How do the Ossiarch Bonereapers differ from the Nighthaunt?
Both are Grand Alliance Death, but they are opposites. The Bonereapers are disciplined, ordered bone constructs that hold firm and grind you down; the Nighthaunt are a fast, chaotic ghost-tide built on fear and vengeance. One is the bureaucracy of death, the other is its nightmare.
Final thought: the Bonereapers won't win a popularity contest at the club bar — they are cold, humourless and a bit terrifying — but if you want an army that plants its feet, refuses to break, and looks immaculate doing it, Nagash's legions are hard to beat.
