Cosmere scholars term the various methods of utilizing Investiture (such as the [[Metallic Arts]], [[Surgebinding]], and [[Awakening]]) '''Invested Arts''',.{{book ref|sa3|part=ars}} Since the Shattering, these can be grouped into three main categories. The most common are those powered directly by the Shards,{{wob ref|4097}} which arise from the interactions between a Shard and the planet they are Invested in.{{wob ref|5269}} Such Invested Arts are capable of far more spectacular results than other Invested Arts.{{wob ref|9385}}{{wob ref|4097}} If a planet does not have a Shard in residence, itits inhabitants can still access and use Investiture by the ordinary laws of Realmatics, but, without a Shard to provide additional power, the results are far more limited.{{wob ref|9385}} The last category is the few Invested Arts left over from before the Shattering of Adonalsium,{{wob ref|4097}} of which the only known example is [[Yolen|Yolish]] [[Lightweaving]].

Much like there is both matter and [[wikipedia: Antimatter|antimatter]], at least some forms of Investiture can be transformed into a substance known as '''anti-Investiture'''.{{book ref|sa4|part=ars}} Currently, the only known forms of [[anti-Investiture]] are [[anti-Stormlight]] and [[anti-Voidlight]], which can be made by at least partially isolating [[Stormlight]] or [[Voidlight]] respectively from their Shard's pure tone and then exposing it to their Shard's opposite tone;{{book ref|sa4|97}}{{book ref|sa4|104}}{{wob ref|14778}} [[Khriss]] seems to believe additional forms of anti-Investiture are possible.{{book ref|sa4|part=ars}} Anti-Voidlight, at least, looks mostly similar to regular Voidlight, but appears to warp the air around it.{{book ref|sa4|97}} When anti-Investiture mixes with Investiture of the same type, the two annihilate in a violent explosion; if the Investiture in question is the soul of a person or that of an entity composed entirely of Investiture, like a [[spren]], then this annihilation results in their permanent death.{{book ref|sa4|97}}{{book ref|sa4|104}}
