Demon Idol contains several rules extensions. These are always marked with an ^Ex. This mark indicates that the rule is not a part of an official publication. Instead, it's a rule that extends the game in fashion we feel is in the spirit of the rules.

Since Demon Idol is about convention over configuration, we recommend adopting all rules extensions. If you find that a rules extension doesn't work for you, you can throw it out. We also hope you let us know by emailing eapoems@riseup.net. Feedback is deeply appreciated, and we hope to get a lot of it.

Any rules extensions which have not been sufficiently playtested will be marked as such.

Most rules extensions are found on the page regarding the rules they extend. There are some rules extensions which are entirely new systems, though. The following is a list of such rules:

- Lair Hunting - Class Quest - Character Token - Wills - Final Words
