Constrict (Ex)

As a swift action, a marilith can transfer a target grappled by its tail slap into its coils and crush their body. This deals 6d12+25B damage to the grabbed target, who must also make a DC 22 Fortitude save or lose 1d4 rounds of holding their breath to avoid suffocating.

Infuse Weapon (Su)

Any weapon a marilith wields functions as is infused with the anarchic and unholy infusion. The weapons also counts as cold iron and magic for the purpose of overcoming damage reduction (in addition to retaining the qualities of its actual composition).


Environment any (Abyss)
Organization solitary, pair, platoon (1 marilith, 1-3 glabrezu, and 3-14 babau)

Demons are fiends that originate from a terrifying realm known as the Abyss. It is a place of pure chaos and pure evil, where a constant war is waged to destroy all of creation. Every living creature… every city… every plant… every standing mountain… entire worlds, if possible, are the ideal target of destruction for a demon.

Demons exist solely to destroy everything they see. While their fiendish counterparts – the devils – seek to manipulate mortal minds and souls, demons desire only to annihilate them. They feed off suffering, mayhem, ruin, and conflict.

Unlike devils, who were once either fallen angels from Heaven or mortals that have had their souls corrupted into a fiendish form, demons are beings created from pure chaos. They are spawned by the foul corruption of the Abyss; an infinite realm of cruelty and depravity. Whenever great death and destruction occurs in the mortal realms, demons begin spawning in ever greater numbers in the Abyss; the wake of destruction seems to call these fiends into existence.

The many different demonic realms of the Abyss are uninhabitable by mortal standards. The rivers and seas are made of acid. The air is poisonous to breathe. Even the land and its plant life seek to devour any unfortunate enough to not watch their step. Demons are properly suited to exist in an environment such as this.

Mariliths are the leaders of the Abyssal hordes and queens of the Abyssal realms. They thrive on grand strategies and plans that will bring about the most destruction across the world. As such, they serve as the generals and advisors to the demon lords of the Abyss.

A marilith appears to be a humanoid woman with six arms from the waist up and has a serpentine lower body. They are often quite alluring, wearing only jewelry. A marilith stands about 9 feet tall and measures 20 feet from head to tip of tail. It weighs about 4,000 pounds (400 bulk). All mariliths carry an arsenal of weapons at all times. Usually this is a sextet of swords, although it can include any number or type of hand-held weapon.
