Ioun stones, originally called Congenio's pebbles,[2] were magical stones that granted enhancements or powers to a creature.[3][1]

Description

They were small, crystalline stones, coming in a wide range of colors and shapes that determined their powers.[1]

Powers

Ioun stones hovered permanently in the air.[1]

When one acquired a stone and wished to receive its benefits, they had to first hold it for a brief time and then release it. Thereafter, when functioning, the ioun stone floated in a circular pattern around the bearer's head, at a distance of 1–3 ft (30–91 cm). They could only bestow their benefit on an owner when within this range. Two stones of the same type would repel each other.[3][1] Another person could try to catch or net the stone to steal it, or break it. 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.[1]

The stones granted various benefits based on their color, as listed below. When drained of power, a stone became a dull grey, but it still possessed the characteristic floating power.[3]
