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.
