Multiples of an ioun stone

[Reg06]

Can a character benefit from two inferior ioun stones of the same variety? For example, a cracked and a flawed ioun stone for a +1 competence bonus and +1 morale bonus to attack.

[Fromper]

As long as they don't give the same bonus, they'll stack.

[Guru-Meditation]

Yes. They are slotless items.

[James Risner]

Yes in all ways.

• Different Source (while the same base item, one is cracked and one is flawed)
  
• Different Bonus (one is competence and one is morale)
