Glittering jewels encrust this leering skull as it floats up into the air on a swirling vortex of dust and shimmering magic.
In their endless years of unlife, some liches lose themselves in introspection, and can no longer rouse themselves to face the endless march of days. Still others cast their consciousness far from their bodies, wandering planes and realities far beyond mortal ken. Absent the vitality of the soul, such a lich's physical form succumbs to decay over the centuries. In time, only the lich's skull remains intact. Yet the bonds of undeath keep the lich's remains from final dissolution. Vestiges of the lich's intellect remain within the skull, and wake to terrible wrath should it be disturbed. Traces of the lich's will to live strengthen the skull, rendering it harder than any steel. The lich's greed and lust for power manifest in the growth of gems in its skull. Lastly, though only the barest remnants of the lich's eldritch might survive, a demilich aroused to anger still retains enough power to flense the very soul from any defiling its final rest. The lich's phylactery invariably fails during the slow decline of lich into demilich, losing its last vestiges of enchantment if not crumbling into dust with the lich's body. But even without the preserving power of the phylactery, demiliches retain a tenacious grip on existence. Only powerful and precise use of magic can permanently destroy a demilich and its remains. To the unwary adventurer, a demilich looks like nothing more than dust and bones within the lich's former sanctum. Indeed, until disturbed, a demilich has only the vaguest awareness of intruders, and ignores their presence. Any attempt to steal the demilich's possessions, disturb its remains, or harm its domain rouses the demilich's slumbering mind, causing it to rise up in the air and voice its wail of the banshee before again settling to the ground. Should the interlopers relent, the skull returns to its torpor. But if they persist, the skull rises again, not to rest again until all in its sight have perished. Fortunately for intruders, demiliches never pursue those wise enough flee. BECOMING A DEMILICH Most demiliches achieved their state through apathy, not volition. For each decade that a demilich fails to stir itself to meaningful action, there is a 1% cumulative chance that its corporeal body decays into dust, save for the skull. Any return to activity resets the chance of transformation to 0%. Once the lich's body decays, the lich's intellect returns to its phylactery as normal. However, the skull rejects the return of the lich's consciousness, keeping the lich trapped in its deteriorating phylactery for 1d10 years. If during that time the lich's remains are destroyed or scattered (for example, by wandering adventurers), the lich's phylactery forms a new body and the intellect leaves the phylactery as normal, returning the lich to life. But if the lich's remains survive unperturbed, the phylactery's magic fails catastrophically, releasing the lich's soul and causing 5d10 points of damage to the phylactery. Regardless of whether or not the phylactery physically survives, the energies released by its failure channel into the lifeless skull of the lich, allowing the last remnants of the lich's soul to transform it into a demilich. The lich's soul itself either is utterly destroyed, reaches its final reward or punishment, or is condemned to wander the edges of the multiverse forever. For wandering liches, the process is similar, but based on the number of decades the lich spends without its intellect returning to its body. While the lich's body still decays, its mind remains at large, only becoming trapped in the phylactery if the lich tries to return during the period in which its body has failed, but it has not yet become a demilich. Should the lich's phylactery fail before the wandering lich returns, the skull becomes a demilich, and the lich's mind is doomed to wander until the end of days. AWAKENED DEMILICHES Under exceptional conditions, a lich's full consciousness survives its transformation into a demilich, or a lich's wandering intellect manages to return to its jeweled skull. Such creatures are awakened demiliches, and combine the powers and near-invulnerability of a demilich with the mind and spellcasting prowess of a lich. An awakened demilich has the full spellcasting abilities of the lich it was before, and gains Eschew Materials and Still Spell as bonus feats. Awakened liches keep their original lich Hit Dice, and any mental attributes that are higher than the demilich's minimums. They otherwise have all the special abilities and defenses of a demilich, except torpor, and no abilities of the original lich beyond spellcasting and mental attributes. An awakened demilich has a CR of 16, or the CR of the original lich + 3, whichever is higher.
