(The WoB referenced doesn't specify that Vasher doesn't know how to convert Stormlight to Breaths, but it does name Vivenna and Hoid. In fact, it specifies that Vasher uses Stormlight to keep himself alive.)

== Appearance and Properties ==
Stormlight appears as luminescent white vapor with a faint blue tint. When free, it behaves similarly to smoke, dissipating in puffs and leaving trails when its source moves.{{book ref|sa2|85}} [[Gemstone]]s left outside during a [[highstorm]] absorb it, becoming infused, which manifests as the gems glowing.{{book ref|sa1|11}} The amount of Stormlight collected is not directly proportional to the strength of the highstorm.{{wob ref|11482}}
 
Absorbed Stormlight, if unused, will eventually begin leaking out through miniscule cracks in the gemstones.{{wob ref|15131}} The speed at which it leaks varies depending on its current vessel. A person can only hold Stormlight for a few minutes at most, while a gemstone will hold it for several days -- the ones used as currency glow for about a week, while bigger gems last a while longer.{{book ref|sa1|prologue}}{{book ref|sa1|17}}{{book ref|sa2|83}} [[Perfect gemstone]]s, like the [[King's Drop]], can hold it for centuries, if not forever.{{book ref|sa3|i|13}} When leaking from gems, Stormlight assumes their color.{{book ref|sa1|56}} It can be transferred from one gemstone to another through various means, such as using tuning forks that resonate to Honor's pure tone.{{book ref|sa4|42}}
Stormlight is the primary fuel of [[Surgebinding]] abilities. To absorb it, a Surgebinder breathes it in from sources such as gemstones or the [[highstorm]] itself. When inhaled, Stormlight gives the user a sensation of increased energy, restlessness and desire to move, with several people comparing it to a storm raging inside them.{{book ref|sa2|42}}{{book ref|sa2|89}} While held, it will automatically heal wounds, exhaustion and even conditions such as poisoning or drunkenness.{{book ref|sa1|38}}{{book ref|sa3|18}} If the Surgebinder is pregnant, then the child can also be healed by Stormlight.{{wob ref|14919}} Stormlight doesn't give the Surgebinder much additional raw strength.{{book ref|sa4|39}} It can also be consumed to power the use of [[Surge]]s.{{book ref|sa2|7}}
 
There are other methods of obtaining Stormlight, such as the method used by [[Vasher]], which can be used by others.{{wob ref|5727}} Stormlight can serve as replacement for other forms of [[Investiture]], most notably [[Breath]]. A [[Returned]] can survive off consuming it.{{wob ref|4553}} Likewise, [[Nightblood]] can be fuelled by Stormlight, and when unsheathed, will begin to absorb it from its environment before going for living beings.{{book ref|sa3|119}} It's possible to transform Stormlight into Breath and use it in [[Awakening]], though that is noted as extremely difficult, with neither [[Vasher]], [[Vivenna]], noror [[Hoid]] having figured out how to achieve this so far.{{wob ref|12667}}
 
[[Fabrial]]s will not function unless the gems comprising them are infused with Stormlight.{{book ref|sa1|part=ars}}
