I think allowing only one boon would fix the issue. I don't think allowing the boon only to last the adventure is a good idea since they are usually given out instead of treasure. Adventure judges keep an eye on things anyway, so there is a less potential for abuse (there is character approvals as well).
What if a character already has more than one boon if this gets voted in? (not that I know of any) Would they be "grandfather clause-ed" in until they switch boons? Also, would a character be able to "sell" a boon (at the boon level or level they got it at with custom boons) or would it just replace the current boon?
