The Ritual of the Lich

To cast this spell, the blood of two loved ones is required. The ritual only works if the caster is the one to take their lives. One of the victims must be older; perhaps a parent, mentor, or lover. The other must be younger; perhaps a friend, child or lover. When both victims are slain, a concoction of their blood must be made and drank under the full moon, new moon or an eclipse. After uttering the forbidden words, a specter of death will appear and lock away the caster's soul within the phylactery. The caster's body will remain dead for 1D4 days before he will regain consciousness.

Once obtaining Lichdom, the Caster's alignment is turned to Evil. The caster gains the Rejuvenation and Turn Resistance Features of the Lich and gain True sight to a distance of 120 ft. They have resistance to Cold, Lightning and Necrotic damage, and immunity to poison; Bludgeoning, piercing and slashing damage from non-magical weapons. They also learn the spells Mage Hand, Animate Dead, Cloud Kill, and Finger of Death if they haven't already.

A Lich turned in this way must consume the souls of the innocent to maintain its sanity. A Lich must roll a D20 every day he doesn't consume a soul. The DC of this check starts at 5 and goes up every day the Lich goes without consuming a soul. If the lich fails a save, he gains two levels of exhaustion that can not be cured except by consuming a soul. The DC of the check goes up an extra point for every level of exhaustion the Lich has. If a Lich dies of exhaustion in this way, then he becomes a Demilich and become an NPC in the DMs control. Only a wish spell can return a Demilich to a Lich form.
