Essence of the Lich
By consuming the essence of the Lich, you gain several boons:
No Basic Needs: You no longer require eating, drinking, sleeping, or other basic needs of living creatures.
Undead Body: Your body is undead, making you immune to fatal damage unless completely destroyed. If destroyed, your body will be rebuilt from a nearly indestructible phylactery that houses your soul.
Tireless: You have limitless stamina and feel no pain.
Immunity: You are immune to disease and poison.
Soul Manipulation: You can manipulate spirits and souls, consuming them to increase your power in various ways.
Miasma of Death: You can generate, manipulate, and control a miasma of death with extreme entropic effects on anything it targets, including immortals.
Necromancy: You can raise, summon, create (from nothing), and command the dead and undead. You can bring back any dead entity as long as you have its corpse, fragments, or soul. These undead are absolutely loyal and cannot be turned against you. Hostile undead must be overpowered or slain before you can control them. You can also animate vehicles, objects, and buildings, even if they are wrecks.
