The immortality granted to a lich lasts only as long as it feeds mortal souls to its phylactery. If it falters or fails in that task, its bones turn to dust until only its skull remains. This "demilich" contains only a fragment of the lich's malevolent life force-just enough so that if it is disturbed, these remains rise into the air and assume a wraith-like form. The skull then emits a terrifying howl that can slay the weak-hearted and leave others trembling with fear. Left alone, it sinks back down and returns to the empty peace of its existence.

Few liches seek to become demiliches, for it means an end to the existence they hoped to preserve by becoming undead. However, time can erode the lich's reason and memory, causing it to retreat into its ancient tomb and forget to feed on souls. The spells it once knew fade from its mind, and it no longer channels the arcane energy it wielded as a lich. However, even as a mere skull it remains a deadly and vexing enemy.

Enduring Existence. Even after a lich is reduced to a demilich state, its phylactery survives. As long as its phylactery is intact, the demilich can't be permanently destroyed. Its skull reforms after 1d10 days, restoring the creature to its wretched state. If it has the presence of mind to do so, a demilich can reclaim its former power by feeding just one soul to its phylactery. Doing so restores the demilich to lich form, reconstituting its undead body.

Undead Nature. A demilich doesn't require air, food, drink, or sleep. So great is a demilich's will to survive that it always has the maximum number of hit points for its Hit Dice, instead of average hit points.

A Demilich's Lair. A demilich hides its earthly remains and treasures in a labyrinthine tomb guarded by monsters and traps. At the heart of this labyrinth rests the demilich's skull and the dust from its other bones. In its crypt, a demilich has access to lair actions and additional uses for its legendary actions. Its whole lair also has unique traits. A demilich in its lair has a challenge rating of 20 (24,500 XP).


Acererak and His Disciples. The transformation into a demilich isn't a bitter end for all liches that experience it. Made as a conscious choice, the path of the demilich becomes the next step in a dark evolution. The lich Acererak-a powerful wizard and demonologist and the infamous master of the Tomb of Horrors-anticipated his own transformation, preparing for it by setting enchanted gemstones into his skull's eye sockets and teeth. Each of these soul gems possessed the power to capture the souls on which his phylactery would feed.

Acererak abandoned his physical body, accepting that it would molder and dissolve to dust while he traveled the planes as a disembodied consciousness. If the skull that was his last physical remains was ever disturbed, its gems would claim the souls of the insolent intruders to his tomb, magically transferring them to his phylactery.

Liches who follow Acererak's path believe that by becoming free of their bodies, they can continue their quest for power beyond the mortal world. As their patron did, they secure their remains within well-guarded vaults, using soul gems to maintain their phylacteries and destroy the adventurers who disturb their lairs.
