Price 16,000 gp; Slot none; CL 12th; Weight —; Aura strong transmutation

This stone grants you a +2 enhancement bonus to any one ability score of your choosing. The selected ability score can be changed only once per day at a time unique to each stone (typically sunrise or sunset). A stone attuned to a specific ability score maintains that attunement until changed at the specified time of day, regardless of how long it has remained unused or how many times it changes hands.

Cracked: This stone grants you a +2 competence bonus on checks with any one skill you choose, and you can change the skill modified once per day, as a normal magenta prism ioun stone. Price: 800 gp.

Flawed: This stone functions as a normal magenta prism ioun stone that has 4 charges. Changing the ability score modified uses 1 charge, and the stone loses the ability to change when reduced to 0 charges, though it still grants a bonus to the ability score to which it was last changed. Price: 12,000 gp.
