Appearance and Properties
Gemstones left outside during a highstorm become infused with Stormlight. The amount of Stormlight collected is not directly proportional to the strength of the highstorm. When Stormlight is not encased within a gemstone, such as when held by a Surgebinder or leaking from damaged Shardplate, it appears as a luminescent white vapor. It also increases the speed at which plants grow.
Nightblood, the sentient sword from Nalthis, is powered through the use of Breath. Nightblood can also use Stormlight. This can be seen when Szeth uses Nightblood in the battle of Thaylen Field. The sword consumes a great deal of Stormlight from both him and Lift.
Everyone who uses Stormlight for Surgebinding, perceives the "sucking in" of Stormlight slightly differently.
Stormlight can be used to fuel the operation of fabrials or Surgebinding abilities.[expand] To use Stormlight, a Surgebinder breathes in the Stormlight and then uses it to power their usage of the various Surges.
Stormlight is used as a currency in Roshar's Cognitive Realm, with moneychangers in Celebrant storing it in perfect gemstones which never go dun. A device is used to transfer stormlight from smaller gemstones into the perfect gemstones, and in exchange one receives credit which can be spent in the city.
