'''Raysium''' is the God Metal ofassociated with the Shard of [[Odium]]. It is rare and available only to a select few amongst Odium's forces.{{book ref|sa4|97}}
 
== Properties ==
=== Physical Properties ===
words words?
Raysium is a bright golden metal, so light it is almost white.{{book ref|sa3|121}}
 
=== Investiture Conductivity ===
Raysium can naturally conduct Investiture, drawing it in from any source. This applies to all of the [[Lights]], but also to spren - allowing someone to transfer spren between gemstones, including spren halves produced during the creation pairing fabrial.{{book ref|sa4|84}}
Raysium can naturally conduct Investiture, without the need for mechanical aids.
 
== Uses ==
As raysium has no notable physical properties, most of its uses have to do with its ability to conduct Investiture.
 
=== Weapons ===
Odium's forces have been using raysium in weapons for several Returns leading up to the True Desolation, utilizing the metal's Investiture conductivity to drain enemy Radiants of their Stormlight, and also fill gems with Light.{{book ref|sa4|84}} The spears used by the ''[[shanay-im]]'' during the True Desolation are likely such weapons.
Vyre's knife, Raboniel's soul-harvesting knives, and Fused spears probably
 
Soon after the imprisonment of [[Ba-Ado-Mishram]] during the [[False Desolation]], a Fused known as [[She Who Dreams]] realizes that raysium could also be used to direct the soul of a [[Herald]] to a gemstone prison.{{book ref|sa4|84}} At least a few such soul-harvesting daggers have been created in the years since - the knife used by [[Vyre]] to kill [[Jezrien]] is one of them, and [[Raboniel]] is in possession of at least two more during the occupation of Urithiru: one she uses to permanently kill [[Essu|her daughter]] (and is later used by [[Navani]] to mortally wound the Lady of Wishes herself{{book ref|sa4|106}}), while the other is charged with [[anti-Stormlight]] and given to Vyre to eventually be used against [[Phendorana]].{{book ref|sa4|102}}
 
=== Fabrials ===
Raysium has no known uses in cage construction, but its ability to transfer Investiture - spren, specifically - from one gem to another allows for a half-spren trapped in one half of a conjoined pair of gems to be transferred to another gem, not part of the original pairing. This can lead to an asymmetry between the movements of the two spren halves, as moving a larger gem a certain distance will now make its smaller paired counterpart move a larger distance.
Not known uses in cage construction, but it can be used to move one half of a split spren in a different gem without the spren escaping
