Lich Transformation 1 Flaw: Phylactery

You have successfully torn your soul from your body and trapped it in a suitable object. The object must be a trinket or item no larger than 1 square foot in size. This item becomes your phylactery.

Phylactery.  A Phylactery is an enchanted vessel containing a Lich's soul. Additionally, a phylactery is a conduit for the Lich to feed on captured souls.

A phylactery has the following statistics:

-Armor Calls: 18

-Hit Points: 90

-Speed: 0

-Damage Immunities: poison, psychic, bludgeoning, piercing, and slashing from non-magical sources.

-Damage Resistances: necrotic, cold, thunder, lightning, force, fire.

When a soul is stored in your phylactery, the phylactery is considered charged. Its charge level is equal to the CR of all the creatures whose souls you have captured. To store a new soul in your Phylactery, add the CR of the creature you killed in your Phylacteries charge level. The souls of creatures with a CR of less than 1/4 are not great enough to charge your phylactery. Your Phylactories charge level cannot exceed 27.

If your phylactery is reduced to 0 hit points, your soul is lost; you crumble to dust and are killed outright.

If you are killed and control a charged phylactery on the same plane of existence, your phylactery's charge is consumed and your body is reconstructed within 5 feet of your phylactery 7 days later. If you are killed and your Phylactery does not have a level of charge, you are reanimated 7 days later as a Demilich under the GM's control.
