Welcome to the ARCANUM—the knowledge keeper for ARC. You won’t adventure alone.
Here are reference documents, from rules to rulings, to help you enjoy ARC’s contents for free.
The ARCANUM doesn’t contain Spells, Techniques, and Creatures (for now!). It’s a living document and may be updated from time to time
to gather additional common alternative rulings and guidance for creators. If you are new to ARC, consider going through each category in order.
