Undead Creatures
Undead creatures arise from the death of natural creatures, often humanoids, that are given new life by an infusion of necromantic energy. Some of these creature are simply reanimate corpses, having lost all knowledge and memory of their former life and continuing on as Mindless automatons. Others maintain their abilities and memories from life, simply gaining new form and ability from the necromantic energies infusing them. Since all Undead are considered "dead", they are immune to Necrotic damage, Death effects , and Energy Damage. Additionally, they are also immune to conditions and effects that require a living anatomy, such as Disease, Poisons & Toxins, Sickened and Nauseated conditions, and Sleep. All Undead are susceptible to, and most are Vulnerable to Radiant damage.
