Wondrous Items - Ioun Stones

Description Source: Pathfinder Society Primer

Resonant Powers

When an ioun stone is set within the special indentation in a wayfinder, a secondary resonant power sometimes manifests to augment the ioun stone’s powers, though this suppresses the wayfinder’s normal magical abilities. This minor function is in addition to the stone’s normal abilities, which continue to affect the wayfinder’s bearer as though the stone were orbiting her head. Two resonating wayfinders wielded by the same character suppress one another’s abilities, but both return to normal when one wayfinder is set aside.

Only 75% of ioun stones grant resonant powers when placed in a wayfinder.

Cracked Ioun Stones

A cracked ioun stone bears an obvious chink or cleft; its power is usually the same as that of an undamaged stone, but weaker. Only 25% of cracked ioun stones grant resonant powers when placed in a wayfinder.

Flawed Ioun Stones

A flawed ioun stone’s power is usually similar to and weaker than that of a normal ioun stone, but sometimes it has side effects or slightly different effects than its normal counterpart. Only 25% of flawed ioun stones grant resonant powers when placed in a wayfinder.

Description Source: Ultimate Equipment
These crystalline stones always float in the air and must be within 3 feet of their owner to be of any use. When a character first acquires a stone, she must hold it and then release it, whereupon it takes up a circling orbit 1d3 feet from her head. Thereafter, a stone must be grasped or netted to separate it from its owner. The owner may voluntarily seize and stow a stone (to keep it safe while she is sleeping, for example), but she loses the benefits of the stone during that time. Ioun stones have AC 24, 10 hit points, and hardness 5. The powers of each stone vary depending on its color and shape.
Regeneration from the pearly white ioun stone works like a ring of regeneration. It only cures damage taken while the character is using the stone. The pale lavender and lavenderand-green stones work like a rod of absorption, but absorbing a spell requires a readied action, and these stones cannot be used to empower spells. Stored spells in the vibrant purple stone must be placed by a spellcaster but can be used by anyone (see ring of minor spell storing).
