Each carries a complement of necrocaches – devices once toyed with by Nagash before being left to gather dust in ancient necropolises around Shyish. When shattered they release a cloud of grave sand that rapidly desiccates flesh on contact, leaving only a skeleton behind – or a convenient downpayment on the bone-tithe depending on your perspective. Sharing orders across a unified mind, units of Mortis Reapers act with the terrifying synchronicity that unnerves even their fellow Ossiarchs, to say nothing of the dread they inspire in the living.
Battletome: Ossiarch Bonereapers
Every single one of these new units and heroes will have rules in Battletome: Ossiarch Bonereapers. We can’t promise it will give you the distilled knowledge of countless military generals – even our writers have their limits – but it will provide you with a wide range of new tactical and strategic options.

Inside you’ll find lore and history for the Ossiarch Empire and their deathless legions, accompanied by gorgeous art and miniatures photography. The Ossiarch Bonereapers also received an updated battle trait, which reinvents Relentless Discipline – your heroes on the field now generate a pool of points you can spend to use various abilities. Katakros himself generates 10, while a Liege-Mortek creates 5, with some abilities gaining power for additional points spent. We’ll be covering this in greater detail on Warhammer Community closer to release.
Additionally there are rules for two Armies of Renown – one of which is the cavalry and chariot focused Lance of Ossia – two Regiments of Renown, a new Spearhead, and Path to Glory rules including an Anvil of Apotheosis, so you can play Mortisan and build your own osseous overseer. There will also be a gamer’s edition, separate warscroll cards, and dice available.**
Battleforce: Null Myriad Phalanx

Releasing alongside the new battletome and miniatures is a battalion boxed set. It’s a bumper bundle of bones carefully arranged into a powerful force under the command of Arkhan the Black, Mortarch of Sacrament. He is joined by a Mortisan Soulmason, four Morghast Archai – which can alternatively be built as Morghast Harbingers – and a unit of 20 Mortek Guard. It’s a great way to kickstart your own tithe-reaping force.
Spearhead: Kavalos Vanguard

The Kavalos Vanguard is a brand new Ossiarch Bonereapers spearhead which utilises a nimble Teratic Cohort to pin enemies down ahead of a cavalry charge. A Liege-Kavalaos and two units of five Kavalos Deathriders are the primary damage dealers, while the Teratic Cohort can be relied upon to claim objectives and herd enemy forces under the hooves of their masters.
Regiment of Renowns: Heralds of the Bone-tithe

One of the two Regiments of Renown in the Battletome will be available to buy alongside the initial release – the Heralds of the Bone-tithe. This small force is led by Vokmortian, Master of the Bone-tithe, who joins the vassals of Nagash to impress upon them the importance of their help in ensuring their dues are paid. It also contains three elite Immortis Guard and 10 Mortek Guard, ensuring that Nagash’s emissary can conduct his duties unhindered.
There we have it – a whole Ossiarch Bonereapers announcement without one single humerus comment about bones. We’re going to give ourselves a pat on the back with our one remaining arm. You can check out the rest of today’s awesome reveals by clicking the button below.
