The 2023 rules manual is here, and the rules section on the site has been updated to reflect both Ren and Dyad Saber. Among the most important changes:
Dyad Saber added — One primary saber and one parrying saber may be equipped at the same time.
Attacks that whip or wrap around the Ren Saber guard, or would otherwise be considered indirect by previous standards, are now considered inert; these attacks do not score and do not stop the action, and are considered a good block.
The errant (late) attack is now defined by the remainiing degrees of arc required to reach the target.
Novice rules added
Document streamlined
Document totally enumerated for easier reference.
A visual scoring guide has also been added, complete with GIFs!
A few more important rule changes will be coming down the pipeline. Stay tuned.
