TTRPG news · Source announcement: 2026-11-10
Kobold Press has issued a new round of errata for Book of Blades, its martial-options supplement for Tales of the Valiant. The November 3, 2026 update adjusts rules across class features, combat, and weapons—and existing owners do not need to buy a replacement to get it. PDF purchasers can download the revised file from their library, while print owners can use a free errata PDF to update their physical copy.
An update to an existing Tales of the Valiant supplement
Book of Blades is a 220-page collection of player options for Tales of the Valiant, focused on expanding combat and martial-character customization. This announcement is an errata release for that book—not a new edition or a separate game.
Kobold Press dates the errata to November 3, 2026, and published its announcement on November 10. The distinction matters: November 3 identifies the errata, while November 10 is the announcement date.
What the errata changes
The revisions cover class features, subclass abilities, martial talents, weapon mechanics, and other rules across the book. Kobold Press highlights adjustments to the Frostborn Raider, Iron Bastion, Skirmisher, and Mechanist, alongside weapon options and martial arts weapons.
The examples suggest a practical mix of clarification and mechanical revision rather than one sweeping redesign. For a group already using these options, the useful next step is to check the complete errata against the characters and rules your table actually uses.
- Frostborn Raider features receive clearer ice-gauntlet rules and revised options.
- Iron Bastion shield mechanics and Skirmisher features are adjusted.
- Mechanist feature wording and augment mechanics are refined.
- Weapon properties and selected options, including Disarming Twist and Weapon Trap, are revised.

How current owners can update
If you bought the PDF, Kobold Press says your copy has already been updated. Sign in to your Kobold Store account and download it using the existing library link; there is no need to purchase the supplement again.
A physical-book owner can keep the existing copy and download the free Book of Blades Errata PDF. The publisher’s suggested approach is to print the updated pages and add them to the book. That means print owners may need to consult separate replacement pages rather than a newly printed volume.
What new buyers and tables should know
Kobold Press says new print copies featuring the updates are available, and names its store, DriveThruRPG, and Amazon as places to obtain a new copy. Availability can change, so check the retailer directly before making plans.
For groups using Book of Blades now, consider agreeing on which version is in use before play, especially where a revised feature affects a character’s tactics. That is table-management advice, not a publisher requirement. The announcement does not describe a new Tales of the Valiant rulebook or promise that every existing book is compatible with every other ruleset.
