These variant ioun stones resemble a thorny sphere—each possesses a circular shape with dozens of needle-like points jutting out. Each type of stone is a different color and grants its wearer a +2 competence bonus on checks for a specific combat maneuver. All varieties of thorny ioun stone have the same price and cost (unless they are cracked or flawed).
Flawed: The flawed version of a thorny ioun stone of any type functions as the normal version, but the wearer also takes a –2 penalty to CMD against the corresponding type of combat maneuver check. Price: 6,900 gp.
See Inferior Ioun Stones for details on cracked and flawed variant stones.
Resonant Powers: A thorny ioun stone’s resonant power grants the bearer the benefit of either the Acrobatic or the Athletic feat. The feat varies by individual ioun stone, and each is equally likely (50% chance).
