The core second edition rulebook includes all content from Vaults of Vaarn Issues 1-3, as well as both Adventure Packs. There is also content that previously appeared on Patreon and on my free blog, and some new content written specially for the 2E book. Vaults of Vaarn Issue 04 and Pariahs of Vaarn 01 have minimal overlap with the core rulebook, with only the Alchemy rules and Quantum Daemon summoning rules respectively being reproduced. These zines are offered as add-on products.

No, the core rules continue to be a mutation of the original 2018 release of Knave 1E. There is no deliberate continuity with Knave 2E, although the systems remain quite similar mechanically.

BackerKit Crowdfunding is an all-or-nothing collaborative funding platform. Creators share their project ideas and set a funding goal with a deadline. Backers pledge money to help make the project possible.

If the project meets its goal by the deadline, pledges are charged and the creator moves forward. If it doesn’t, no one is charged.

Pledging in crowdfunding is a commitment to support the creation of a new product or project. Unlike a traditional purchase, you're not buying an item that already exists. Instead, your contribution helps bring a creative idea to life, and in return, you typically receive rewards (such as the product itself) as a thank you for your early support.

1. Select a pledge level with the reward(s) you would like to receive
2. Select any add-ons
3. Confirm your pledge!

• You are charged only if the campaign meets its funding goal.
• Charges happen when the campaign ends, not when you pledge.

After the campaign ends, you'll receive a survey to pay for any applicable shipping fees, calculated based on your shipping address.

Pay Over Time allows you to split your pledge into multiple payments over a set period. Your card will be charged according to the payment schedule (four monthly payments). Only available for projects that enable this feature. Learn More »

Only the project creator and the BackerKit Support Team can see your pledge and contact information. Other backers and the public cannot see your individual pledge amount or personal details.

You can change or adjust your pledge level and add-ons before the campaign ends. After the project concludes, cancellations or changes are at the creator's discretion and may depend on what stage the project is in.

Overtime Mode extends your campaign past its original end time to give backers a final chance to make their pledge. It will add an additional 10 minutes past the end time as long as pledges keep coming in. The campaign will end when there is a 10-minute period without any new pledges.

For specific questions about your pledge or the project, you can view the Project FAQ below, search for your answer within the project, or send a message to the BackerKit Support Team or to the project creator.
