Lich ritual

The Lich Ritual is a magical ritual that allows normal beings to become liches.

Things you'll need

 * One vial of water from each of the five Underworld rivers
 * Bone of an ancestor
 * Blood of the caster
 * Mummy linen
 * A vial of ghost ectoplasm
 * Four vampire fangs
 * One vial of hydra venom
 * A vial of gorgon blood, specifically from the left side
 * A phylactery (an object to hold one’s soul).

How to perform

 * 1) Light a black flame using the spell "Illuminabit nigra flamma".
 * 2) When the new moon reaches it’s peak, throw the vial of venom, gorgon’s blood, water from the five rivers, mummy linen, ectoplasm, fangs, bone, and, finally, the blood, all while saying the first part of the spell, "Venenum autem hydram Sanguis goni sinistram, quinque flumina aquae inferis mater lineis ectoplasm larvae, molares eius ut lamia os parentis cruore obducit. Haec utinam flammam dedi te".
 * 3) Finish by placing the phylactery, and finish the spell by saying "Daboque tibi et rei anima taceam, quod fieri non potest attingere mors".

Effect
If performed right, the ritual drains the soul from the body, killing anyone who failed to perform it right or anyone not strong enough to handle the stress of their soul leaving their body, hides it in an object, and transforms the caster into a lich.

Note
Most of the people who have become liches were evil mages. As such, the performance of this spell is considered taboo by magical law.
