Spirit Physiology (Re:Zero)

==Introduction==
Spirits are supernatural beings in the world of Re:Zero, that are born from the Od Laguna- the soul of the world itself and source of all Mana. Spirits both manifest their forms and meddle in the world through the primordial energy of Mana.
==Ability Overview==
Spirits at their most basical level are simply an Od- the core of one's being that is synonymous with the soul- wrapped in Mana to manifest a physical form.
Spirits come in 3 stages of being: Lesser Spirits, Quasi-Spirits, and finally full-fledged Spirits; with particulary strong Spirits being called Great Spirits. 
While they vary massively in power, ability, age, and intellect, all Spirits share the same basic abilities:
*Inorganic Physiology (Type 1; A Spirit's manifested body is composed of Mana,Bond of Ice, Chapter 4 granting various natural resistances)
*Incorporeality (A Spirit's true form is their Od- the core of their being, which is the owner's life energy and synonymous with the soulArc 6, Chapter 86- and their physical body is merely a manifestation created by the Spirit using Mana)
*Immortality (Types 1, 2, & 3; Spirits live forever.Volume 6, Chapter 4 Spirits won't die no matter what happens to their manifested form,Bond of Ice, Chapter 3 and they can easily recover from damage to their manifestation in an instant) 
*Regeneration (Low-Godly; Injury does not exist for Spirits, they will easily recover from any damage to their Mana-based manifested forms, and they can only recieve real damage if their Od- the core of their being, which is the owner's life energy and synonymous with the soul- is targeted)
*Magic and Elemental Manipulation (All Spirits have an instinctual affinity for magic,Re:Loving the Days Gone by From Zero which is most often used for elemental manipulation) 
*Body Control (A Spirit's form is decided upon by themself, thus they can change their sizeVolume 1, Chapter 1 or even reconstruct their own body at will, Tanpenshuu Volume 2, Chapter 6 removing any previous effects, which can for example be used to instantly make themselves sober)
*Telepathy (A Spirit can communicate telepathicallyArc 4, Chapter 92 with either their Contractor or with anyone who has an affinity for Spirits)
*Possession (By gaining permission from someone or by forming a contract with them, a Spirit can possess their body, as long as the terms of the contract allow it) 
*Self-Sustenance (Types 1 & 2; Spirits have no need to breathe or eat as the only energy they require is Mana) 
*Absorption and Sleep Manipulation (Spirits can drain Mana from people,Volume 2, Chapter 1 which can make them faint,Volume 1, Epilogue or outright kill themVolume 2, Chapter 4)
*Intangibility and Invisibility (Spirits are able to dematerialize,Volume 9, Chapter 5 and while dematerialized, a Spirit is invisibleArc 5, Chapter 15)
*Spatial Manipulation (Spirits can manifest themselves anywhere as they traverse spaceBond of Ice, Chapter 2 itself)
*Resistance to Magic (As Spirits are composed of Mana, the defenses of said Mana should withstand intervention of Magic and diminish the might of Magic, so long as the Magical power is not overwhelmingly superior to their own)
==The Exception==
There is a single Spirit that does not possess most of the abilities provided by Spirit Physiology; The Artificial Great Spirit Beatrice. Unlike all other Spirits, artificial or natural, Beatrice cannot use basic Spirit abilities such as dematerializing, or is limited in her use of them such as how she can only make cosmetic changes to her materialized body. This is because Beatrice's body was designed to mimic a human being's as closely as possible,Arc 5, Chapter 12 she has circulation as well as a need to breathe, for example.
