When one acquired a stone and wished to receive its benefits, they had to first hold it firmly for a brief time in order to attune themselves and imprint their own magnetic aura into its structure, and then release it or toss it in the air. Thereafter, when functioning, the ''ioun stone'' orbited the bearer's head at a distance of 1–3 feet (30–90 centimeters), or else trailed after the bearer as they walked.<ref name="Bazaar"/><ref name="EM-vII-p613"/><ref name="DMG35-p260"/> Its path was affected by the user's own magnetic field: it generally followed a circular or elliptic pattern but could at times follow a random path, float unmoving in the air, or dance and bob erratically. Occasionally, a ''stone'' might drift up to 12 feet (3.7 meters) from its owner, then swiftly return. Some users noted that if they examined something closely, then their ''ioun stones'' would move toward it.<ref name="Bazaar"/>

An ''ioun stone'' held stored magical energy. An orbiting stone created a link with its owner, through which it regularly transferred small packets of this energy to them.

The bearer could freely grab and pocket a stone, such as when going to sleep, to keep it safe, but they could no longer receive its benefits. Another person could try to catch or net a hovering stone to steal it or break it. In any case, if shifted more than 3 ft (91 cm) from its owner, they ceased to function.<ref name="EM-vII-p613"/><ref name="DMG35-p260"/> If the user went to sleep without storing them, the stones hovered motionlessly over them. If the user was injured and lay dying, the orbit of the stones slowed and stayed close to their head. If the user died, the stone slowly drifted off in a random direction before slowly falling to the ground. However, if the user died suddenly or violently, the stone flew off at great sped in a random direction, fast enough to hurt if it impacted someone, or else hitting the ground up to 120 ft (37 m) away.<ref name="Bazaar"/>

Some stones had only one or a set number of charges, after which they became drained of power and were considered burned out. Rarely, an ''ioun stone'' spontaneously burned out on its own (a 1-in-20 chance each year). Either way, a burned-out stone became dull grey and inert, but it still possessed the characteristic floating power.<ref name="Bazaar"/> Although they were useless for magical purposes, they retained sufficient resonance for a [[psionicist]] to extract a smidgeon of psionic energy—enough to boost their psionic strength or to fuel the lowest of unaugmented powers—before it became completely burned out.<ref name="Bazaar"/><ref name="XPH"/>

Some ''ioun stones'' were apparently created using essences taken from a soul, and bestowed the benefits of these upon their owners. According to legend, the pearly-white ovoid was created from the enslaved soul of a [[troll]], and granted the troll's ability to regenerate wounds. The ''[[pale green ioun stone]]'' came about when the dying warrior [[Rigar Trueblood]] begged his companion, the mage [[Spectorial]], to preserve his skill and fortitude in battle. Although reluctant, Spectorial acceded and extracted these qualities from Rigar's soul, placing them in an ''ioun stone'' so that others might benefit from them.<ref name="BG1" /><ref name="BG2.SoA"/> The unique ''[[Malla's soul stone]]'', which acted as an ''ioun stone'', contained the soul of an innocent young woman, and conferred many different benefits.<ref name="BG2.ToB"/> Similarly, the ''[[mantle stone of Vhyridaan]]'' was a failed attempt to create a [[tel'kiira|''kiira'']] that absorbed its creator, body and soul. Containing the trapped soul of the mage [[Vhyridaan the Mad]], this unique ''ioun stone'' was a sentient item that Vhyridaan could steer somewhat to evade attacks.<ref name="tFoMD-p47">{{Cite book/The Fall of Myth Drannor|47}}</ref>

On the other hand, some ''ioun stones'' seem to have merely been created from the blood of creatures with the necessary essences. Legend told that the ''[[Trollblood ioun stone]]'', a dark-green sphere, was created from the blood of seven trolls that had each been captured and, over seven nights, used in experiments in magic. The ''ioun stone'' that was produced conferred a weaker form of a troll's ability to regenerate wounds, but also gave great skill in slaying trolls in combat.<ref name="BG1" />

''Ioun stones'' did not need to be set orbiting the head; it was possible to mount them in magical items kept close to the body.

The ''ioun stone'' has its basis in the IOUN stone (written all in capitals) appearing in the short story "Morreion" by [[Wikipedia:Jack Vance|Jack Vance]], whose [[Wikipedia:Dying Earth|Dying Earth]] series was very influential on early ''[[Dungeons & Dragons]]''. "Morreion" was first published in the [[Wikipedia:Flashing Swords! 1|''Flashing Swords! #1'']] anthology in 1973. Here, IOUN stones are valuable items that nullify magic and are extracted at great risk from the cores of dead stars. With Vance's permission, the ioun stone was first developed for D&D in ''[[The Strategic Review]]'' #4 (1975), with the ''clear prism'', ''deep-red sphere'', ''incandescent blue sphere'', ''pale green ellipsoid'', ''pale lavender spindle'', ''pearly white prism'', ''pink ellipsoid'', ''pink-and-green ellipsoid'', and ''scarlet-and-blue sphere'' being the first to appear.

The article "Bazaar of the Bizarre: Ioun Stones" in [[Dragon magazine 174|''Dragon'' #174]] (1991) begins by describing Vance's original IOUN stones and presents two possible origins for the ''ioun stones'' in D&D. The main one is that ''ioun stones'' grow naturally but rarely on the [[Quasi-Elemental Plane of Minerals]], at the intersection of the [[Elemental Plane of Earth]] with the [[Positive Energy Plane]], and the article details the hazards in procuring them. The other idea is that powerful human wizards from another [[Prime Material Plane]] simply manufacture ''ioun stones'', but describes this as straightforward, uninteresting, and lacking adventure.

Nevertheless, ''[[Encyclopedia Magica Volume II]]'' (1995) does just that, stating that the powerful human wizard Congenio Ioun invented them. ''[[Netheril: Empire of Magic]]'' (1996) follows suit, placing this origin in the ''[[Forgotten Realms]]'', telling that Congenio Ioun was a Netherese wizard and that subsequent wizards manufactured more, as recounted in this article. Since this is ''Forgotten Realms'' material, this is the version adopted for this wiki.

D&D would once again forget and recreate the origin of the ''ioun stone'' when 4{{th}} edition introduced a goddess of knowledge and prophecy called Ioun, inspired by the ''ioun stone''. ''[[Open Grave]]'' presents a cursed [[artifact]] called the Jet Black Ioun Stone, and says that the goddess Ioun created ''ioun stones'' (including the Jet Black) to spread knowledge in all forms. However, she was not introduced to the 4{{th}} edition of the ''[[Forgotten Realms]]'' setting (although [[Zehir]] was, who had a hand in the Jet Black), so it must be assumed that neither the goddess Ioun, her creation of the ''ioun stones'', or the Jet Black Ioun Stone exist in the setting. This leaves only their creation by the mortal wizard Congenio Ioun and others.

The drifting of the origin story continued in 5{{th}} edition with the eponymous creator being called a god of knowledge and prophecy, rather than a goddess. The stones were described as having a rigid correlation between the benefit they bestowed and the shape and color of the item. They were considered wondrous items valued by rarity and classified as Rare, Very Rare, or Legendary.

Meanwhile, ''[[Kara-Tur: The Eastern Realms]]'' (1988) introduced ''[[warfu stones]]'' with similar function. These are presumably intended to be an eastern version of the ''ioun stones'' of regular D&D, but a connection between the two is unknown.
