'''Investiture''' is a term describing the energy that infuses the [[cosmere]] and on which all cosmere magic systems are based.
== The Nature of Investiture ==
Investiture transcends the three realms: Physical, Cognitive, and Spiritual that comprise most of the cosmere. However, it is more Spiritual than anything.{{wob ref|5610}} In the Physical Realm, Investiture is known to exist in solid, (i.e. [[atium]] and [[lerasium]]), liquid ([[Perpendicularity|Shardpools]]), and gaseous material forms ([[Mist|Preservation's Mists]], [[
An interesting thing to note is that the color red has a tendency to manifest when a Shard is "co-opting or corrupting another Shard's magic".{{wob ref|8340}}{{book ref|sa3|117}} All Investiture creates some type of emotional reaction in users.{{wob ref|13392}}
=== Anti-Investiture ===
Physical matter is known to have a counterpart called antimatter - matter composed of antiparticles that share many properties with the particles of ordinary matter, but manifest some of them in an opposite way (e.g. a proton and an antiproton have the same mass, but opposite electric charges and magnetic moments). Raboniel describes this in terms of axi with opposite polarities.{{book ref|sa4|97}} A similar relationship exists between Investiture and anti-Investiture in the cosmere. When investiture combines with it's corresponding anti-investiture, they both annihilate resulting in the release of a large amount of energy.{{book ref|sa4|97}} The reaction seems to be more violent when the two are brought together under pressure.{{book ref|sa4|97}}
The only known forms of Anti-investiture are [[anti-Stormlight]] and [[anti-Voidlight]]. It is unknown whether hybrid Lights and Shards outside of the Rosharan system have anti-Investitures of their own. [[Khriss]] states in the Ars Arcanum that, though long theorized, the anti-Lights are her first evidence of an anti-Investiture.{{book ref|sa4|part=ars}}
== Accessing Investiture ==
Many methods of accessing Shardic power have been observed throughout the cosmere, but all share certain cardinal similarities; an established connection or ability to create a connection to a source of power and a way of directing that power. Methods of accessing Investiture can be broadly divided into two types: physical and mechanical; the source of the Investiture (end-positive, end-neutral, or end-negative) also plays a role in the way the power is accessed.
Several end-positive magics share the trait of requiring a Spiritual shift of some kind; Elantrians are more closely attuned to the Spiritual Realm (incidentally, this is why [[Hemalurgy]] gets more from them),{{wob ref|6218}} Allomancers, in Classical Scadrial, had to Snap to access power, and Surgebinders "plug" spren into themselves. Once a conduit has been established, a key, such as an Aon, metal, or Command, is used to tell it how to act.
While a key is generally used, [[Shard]]s can also choose to use their Investiture to power magic: [[Endowment]] breaks pieces off itself to resurrect the [[Returned]], and [[Preservation]] powers Vin's Allomancy with the Mists; some magics, such as [[BioChroma]] and [[Feruchemy]], deal with the use of power that already exists within a human (be that naturally or by Shardic intervention). Others lack an explicit key; instead of pulling power directly from a Shard, Surgebinders draw from the Investiture of highstorms, and direct it through their bond with their spren, similarly to [[fabrial]]s.
== Intent of use ==
The intent of a user is very important to several magic systems
== Color ==
;'''Knights Radiant''': Each Knights Radiant Order is associated with a color. When a Surgebinder summons their Shardblade, their eyes will change to match their Order's color.{{wob ref|6848}}{{wob ref|8628}}
;'''Soulcasting''': When Soulcasting, both Surgebinders and fabrial users are limited by the types of gems available to them.{{wob ref|2784}} While the chemical composition of the gemstone is important, its color is paramount, with every color of a polestone corresponding to one of the [[Ten Essences]].{{book ref|sa3|part=ars}} Some polestones are the same type of crystal but with different color and chemical signatures, such as sapphires and rubies both being types of corundum. Much like how [[iron]] and [[steel]], despite being very similar chemically, are different metals in the Metallic Arts, the exact color and chemical signatures are enough to differentiate the polestones. As a result, an off-color polestone acts much like an impure alloy in Allomancy.{{wob ref|4080}} If a polestone was drained of its color by an Awakener, it would still hold Stormlight but would have the properties of a dusty or cloudy quartz.{{wob ref|3203}}{{wob ref|295}} If a spren was trapped inside,
'''Fabrials''': The color of a gemstone determines its flavor to a spren, and can be used to attract certain types of spren. {{cite}}
=== Healing the soul ===
When healing the soul, such as a missing piece cut off from a [[Shardblade]], a new patch of soul will be created.{{wob ref|126}}{{wob ref|983}} Healing wounds to the soul is much more [[Spiritual Realm]] based.{{wob ref|6435}} If a magic is strong enough to heal from pieces of a body, it will try to heal from the biggest piece.{{wob ref|4128}} If the body was perfectly cut in half, a random half would be chosen to heal from. Not every magic system is capable of healing soul wounds.{{wob ref|6435}} If the soul leaves the body and is then healed, the soul will not return and the physical body will be the only thing healed, leaving the person dead.{{wob ref|9623}}{{book ref|mb3|82}}{{book ref|mb3|epilogue}} If a soul is healed but not reattached properly, the person will leave a glowing afterimage when they move,{{book ref|sa3|90}} though it is only visible to those who are highly invested or connected to the [[Cognitive Realm]].{{
=== Limitations ===
;'''AonDor''': In [[AonDor]], the [[Aon]] Ien is used as the basis for healing.{{book ref|Elantris|19}} To maximize its potential, [[Elantrian]]s use specialized modifiers that can target the part of the body that needs to be healed, as well as define how the healing should take place.{{book ref|Elantris|53}}
;'''Elantrians''':
;'''Forgery''': A form of [[Forgery]] practiced by surgeons is called Resealing.{{wob ref|7759}} Resealing can effect miraculous healing, even allowing to survive otherwise fatal wounds, but it doesn't repair spiritual damage. Forgery can also be used to Forge a new soul.{{tes ref|2}}

It is possible for a natural force to become Invested. On [[Roshar]], [[Zahel]] states that the [[highstorm]]s are Invested.{{book ref|sa2|i|6}} The [[Stormfather]] also states that during a
