Apparition

Habitat
Anywhere spooky enough to have them

ET Notes
The overview does not do how powerful this creature is justice. An apparition is a creature of many souls, bound into one thought-form/entity. All of the souls are tortured by the process of having to share the same mind with 100+ others, and thus the creature is chaotic by definition. The creature is most often seen created in rituals, where a large amount of people are slaughtered at once to create an apparition, but may also be generated by mass slaughters in the general populace, the later being much rarer. The creature attacks in two ways, one using predominantly necromantic powers (Life drain, rising corpses), and the other purely melee in which its punches deal paralyzing damage.

Usually, there exists only one apparition per map due to their power-scale. They are strangely powerful beings, so if a group of necromancers manages to capture one, they've one of the most powerful creatures under their wing. Mind you such a task is nigh on impossible without enough (15+) necromancers all working together with proper containment set up about the area. The exercising of such a creature may be even more difficult, taking an great deal (equal to the number of necromancers needed to trap the entity), to exercise the being at once. The most a singular cleric or paladin may hope to do is strip away a few souls from the conglomerate.

Loot on these creatures does not exist.

An example of an encounter with this creature would take place inside a cave or crypt, a group of priests moving to hunt out the supposed creature. Upon facing the entity, they would have to keep focused whilst waves of zombies were sent at them to exercise the creature, if at all possible.
