Ioun Stones
Wondrous Item, Rarity Varies (Requires Attunement)
Ioun Stones are marble-sized magical items named after Ioun, a god of knowledge and prophecy on some worlds. Each stone is a distinct combination of shape and color, and different types offer different magical benefits.
As a Magic action, you can toss an Ioun Stone into the air, causing it to orbit your head at a distance of 1d3 feet, granting its magical benefit. You can have up to three stones orbiting you at once. While orbiting, a stone is considered a worn object, automatically avoiding collisions and thwarting attempts to attack or seize it.
You can use a Utilize action to seize and stow any orbiting stones. If you end your attunement to a stone while it orbits you, the stone falls to the ground.
Each type of Ioun Stone has its own rarity and effect:
- Absorption (Very Rare): Cancel spells of level 4 or lower as a Reaction. Cancels up to 20 total levels before burning out.
- Agility (Very Rare): Dexterity increases by 2 (maximum 20).
