Anastasis

At 2nd level, you have learned to construct a basic phylactery to ward yourself against the predations of death. The primary phylactery can be stored in a realm of your choice and acts as the Master Phylactery. This Master Phylactery requires you to be attuned to it to receive its benefits. While the Master Phylactery exists and you are attuned to it, you gain the following benefits according to your level:

2-4: While the Master Phylactery exists, you may be revived and resurrected from the dead while requiring only half the material components.

5-8: You gain advantage on death-saving throws and no longer need to eat, drink, and breathe.

9-12: Once per day, you may forge a Phylactery Node. This node connects back to the Master Phylactery. Only a single node can exist at one time for a plane. If you attempt to create a node while one exists on your current plane, the old one crumbles to ash. If your dead body is brought to your Master Phylactery or a Phylactery Node, it casts Raise Dead on you without components. This ability cannot be used again until 7 IRL days have passed.

13-16: You gain immunity to necrotic damage. Moreover, you may choose to be considered to have the Undead creature type as it benefits you. Also, whenever you attempt to long rest near your Master Phylactery or Phylactery Node, the time required to do so is halved.

17-20: Once per 14 IRL days, the Master Phylactery or a Phylactery Node can cast True Ressurection on you without components. If your body is trapped elsewhere, your body and all your possessions are rendered to ash and reformed by the Phylactery (retrieving your gear and your body may only happen once per IRL month).

If the Master Phylactery is ever destroyed, it requires an 8-hour ritual to recreate it as the Phylactery Nodes will be rendered dormant.
