TOPIC: Ioun Stone Longevity

We haven't seen anything on this subject so I thought I would ask. Are Ioun stones limited in use, or are they permanent? Are they destroyed by anything?

<br /><br />They are permanent.  Per previous information from Jeff & Dave, like all permanent tokens, they can be "destroyed" in a dungeon (although I've never heard of that happening to date), but if they are that just means that they aren't able to be used again during that dungeon run.  The player would retain the token, and could use it in future runs. 

Mike's got all the above correct. It's also worth noting, you can have up to 5 stones active at once. Considering only 3 have been printed to date, you're not in any danger of running out of slots yet
