Notes
- The original Kingdom of Loathing Certificate of Participation is obtained by using a Certificate of Participation, which is in turn obtained as a reward for having completed the Toot Oriole Quest.
- The Kingdom of Loathing Certificate of Participation is not affected by ascension; you do not have to re-obtain it in your next incarnation.
- If you don't use your certificate before ascension then you will find you have one at your campground after ascending anyway.
- It is possible to obtain a shiny version of this certificate by attending KoLCon.
- At one point in time, it was possible to obtain a Shiny Certificate by visiting a now removed test page. However, these Shiny Certificates have now been removed and the original certificates have been restored.
