The Ossiarch legions are an undead force like no other. Created to be autonomous, they are trusted to enact Nagash’s will on a hundred war fronts at once. Their empire gathers war materiel from the cadavers of each battle, harvesting bone with which to create new warriors, build fortifications and begin the cycle of death over again.
This page contains all of the rules you need to field your Ossiarch Bonereapers miniatures on the battlefields of the Mortal Realms, from a host of exciting faction rules to a range of warscrolls. The rules are split into the following sections:Contents | ||

Here, you will find additional rules to use with a Ossiarch Bonereapers army while playing through a Path to Glory campaign. The Path to Glory content in this book is divided into two parts: the Anvil of Apotheosis and Paths for Ossiarch Bonereapers units.
| Your Hero's Warscroll You can download a blank warscroll from warhammer-community.com on which to record all of your hero’s details. | ||
| The Anvil of Apotheosis is a hero creator. Using the rules in this section, you can create a custom warscroll for a HERO to use in your Path to Glory campaign. This can represent any miniature of your choosing, including one you have lovingly kitbashed or converted. After the Anvil of Apotheosis, you will find 2 Paths for Ossiarch Bonereapers units. These follow the rules outlined for paths in the Path to Glory battlepack you arc using (e.g. Path to Glory: Blighted Wilds). | ||

| |||||||||||
Origins
PRECISION DUELLIST: This leader has been crafted with single combat in mind, perhaps as a future Liege-Immortis should Karash ever be permanently felled.
METICULOUSLY CRAFTED: With a frame commissioned to reflect a string of impressive victories, this construct is incredibly durable.
WALKING DEATH: This warlord is animated by the spirits of some of the most aggressive and ruthless commanders ever to walk the realms.
KATAKROSIAN DYNAST: This construct has been imbued with soul-stuff from a number of Katakros's lineal descendants, each of whom continued his fine tradition of military excellence - albeit not to the same exemplary level as their forebear. | ||||||||||||||||||
Flaws
HASTILY REPAIRED: The damaged frame of this construct was hurriedly patched up with beast-bone, resulting in bouts of savagery.
OSTRACISED: Tenuously connected to a grievous failure that resulted in a whole cohort of Bonereapers being transformed into Teratic monstrosities, this hero is spurned throughout the Ossiarch legions.
PETTY RIVAL: When ordered to craft a new, powerful frame for this hero's anima, the Mortisan commissioned to fulfil the task took the opportunity to satisfy a long-held grudge. Thus was a deadly imperfection woven into this construct's form.
FOND MEMORIES: This construct is animated by an indelibly melodramatic soul, causing them to experience moments of acute nostalgia that are difficult to banish. | ||||||||||||||||||
War Form -4DP GUARDIAN OF THE EMPIRE: Using the proven chassis of an Immortis Guard or a Necropolis Stalker, this war form is as adaptable as it is powerful. In addition, make the following changes to your hero's warscroll:Replace your hero's melee weapon with the following:
War Form -10DP NIGHTMARISH OSSIARCH: This war form could easily be mistaken for a terrifying beast from the Realm's Edge, and the horror only intensifies as it wields nadirite blades with impressive skill for a creature of its size. In addition, make the following changes to your hero's warscroll:Add the following weapon to your hero's warscroll:
War Form -20DP TOWERING WAR CONSTRUCT: This osseous colossus is nothing less than an undead siege engine. Its immense frame and tactician's cunning make for a lethal combination. In addition, make the following changes to your hero's warscroll:Add the following weapons and ability to your hero's warscroll:
BATTLE DAMAGED Effect: While this unit has 10 or more damage points, the Attacks characteristic of its Crushing Appendages is 5.

Path of The Conqueror(OSSIARCH BONEREAPERS HERO only)ASPIRING: When a unit on this Path gains this rank, pick 1 of the following abilities for them:
AMBITIOUS DUELLIST: This hero seeks to prove Their superiority over all other foes of renown.
SCHOLAR OF THE DEATHLY ARTS: This hero has spent long centuries perfecting their death-based magics.
DEAD GOOD: This hero is animated by souls from some of the mightiest warrior-lodges in the Shyishan underworlds.
OBSESSIVELY STUDIOUS: Secrets revealed to this scholar are known by a mere handful of souls. Effect: For the rest of the phase, this un it can use that ability as if it had the UNLIMITED keyword.
AURA OF THE NADIR: The necrotic energy emanatingfrom this hero drains the enemy's strength. Effect: Subtract 1 from the Attacks characteristic of the target’s melee weapons for the rest of the turn.
NECROMANTIC PRODIGIES: The souls of highly successful necromancers were ground down into spiritual gristle and used as clay to create this construct's mighty soul.
SINGLE-MINDED RUTHLESSNESS: The necrotic energy emanatingfrom this hero drains the enemy's strength.
MASTER OF THE MORTISAN CASTE: This scholar's knowledge of deathly soul-magics and bonecraft is without compare. | ||||||||||||||||||||||||||||||||||

| Critical hits have no effect on their own but often trigger additional effects (see 20.0 Weapon Abilities). | ||
| Sometimes objective markers get accidentally nudged while you are moving models around. This is perfectly fine - just remember to put them back in their proper positions when determining objective control. | ||
The non-UNIQUE WIZARD keyword is used in the following Ossiarch Bonereapers warscrolls:
| ||
| In some cases, it might not be immediately clear whether a model is visible. If so, stoop down to get a look from behind the observing model. If any part of the other model is visible, even if it is just the tip of a spear, then that model is visible for rules purposes. | ||

Passive |
| When moving flying units, move them horizontally in any direction, ignoring intervening models and terrain, and place them where you wish, so long as they are allowed to end their move on that spot. Note that some units have the FLY keyword even if that unit can’t really fly. This often represents units that bounce, bound or skitter across the battlefield so adeptly that they might as well be flying! | ||

| The Citadel Terrain List shows the number of scenery pieces each terrain feature can consist of. If you are using terrain features that are not included on that list, agree with your opponent before setting up the battlefield how many scenery pieces make up each terrain feature. | ||
| Because a replacement unit is treated as a completely new unit, it could, for instance, use a Once Per Battle ability on its warscroll even if the unit it replaced used that ability earlier in the battle. | ||
| ||
| There may be situations when a unit that has STRIKE-FIRST is not in combat at the start of the phase, but because of moves such as pile-in moves, it is ‘pulled into combat’ later in the phase. In such cases, STRIKE-FIRST has no effect on that unit because it was not in combat at the start of the phase. Abilities that allow a unit to use a FIGHT ability immediately after another unit do not override the STRIKE-FIRST or STRIKE-LAST constraints, so you could not pick a unit with STRIKE-LAST to fight immediately after a unit with STRIKE-FIRST. | ||
