From time to time, Wizards of the Coast publishes minor updates to Dungeons & Dragons sourcebooks.

These updates clarify rules questions, correct technical errors, and improve game play. While we make every effort to catch such issues before publication, the sheer volume of material published for the game ensures that a few inevitably creep in.

If you think you’ve found an error in one of our books, please let us know! R&D works with Customer Service to examine each and every potential error brought to our attention, determining what action, if any, needs to be taken to resolve it. All updates are further screened by key members of the development and editing teams before being published here.

Rules updates published on this page are included in the Compendium and Character Builder as part of the soonest available monthly update to those tools.

Each update presented below is the most recent file available for the book in question. Each file was last modified on the date shown (and indicated in the file). In some cases, updates may have been posted at a date after the last modification date.
