Special Abilities

Discorporate (Su) Formed by hundreds of humanoid bones, an ossumental can drop its form into a scattered pile of bones, allowing it to take 20 on Stealth checks to avoid being noticed for what it is. In addition, when an ossumental uses its breath weapon, it can, as a free action, transport itself to any unoccupied area affected by the breath weapon.


Ossumentals are found exclusively in the enigmatic location called the Slave Trenches of Hakotep. It is here where the strong elemental forces and the massive loss of mortal life used to excavate the earthworks combined to create these terrifying creatures.

Hakotep I drove thousands of slaves to dig the elaborate system of earthworks and deep trenches, and though no one’s certain of the site’s purpose, some speculate that it is an arcane device constructed to defend against any perceived Shory invasion using their flying cities.

Obelisks bound with elemental spirits were erected throughout the system, and as time crept along, some of these spirits escaped their prisons and fused with the remains of the slaves who once toiled in the trenches. Now, ossumentals act as unintended guardians and caretakers of the site. Those exploring this region have reported that some of the ossumentals maintain the Slave Trenches of Hakotep by keeping the deep trenches clear of the ever-encroaching desert sands, though they are only successful for a matter of time before the winds drive the sand again.

The creatures aren’t always active; at rest, their bones lie scattered under the oppressive Osirian sun, waiting for living creatures to wander by before clattering together to attack. An ossumental is a tricky combatant, attacking with its four arms in melee combat and then using its breath weapon to attack multiple targets that are out of reach. It makes use of its discorporate ability to quickly shift position on the battlefield and get behind its attackers.

Fully formed, an ossumental stands approximately 16 feet tall and weighs around 300 pounds.
