Errata for the Monster Manual and the Dungeon Master’s Guide

Like the Player’s Handbook back in June, we now get errata for the Monster Manual and the Dungeon Master’s Guide for people who rushed out to get the books. Recent books are already fixed and have the errata in their copy. I’ve included a short overview for everyone and links to the full documents. I’m still trying to figure out exactly how impactful these changes are.

Monster Manual Errata

  • PDF is 2 pages and mostly includes minor changes to wording
  • Increase in the XP awarded for ancient dragons
  • Changes to wording and stats for various monster, such as immunities, saving throws, skills, damage, etc from Aarakocra to Young Brass Dragon
  • Recent printings of the book, starting with the third, include these changes.

Dungeon Master’s Guide Errata

  • PDF is a single page
  • Changes are mostly minor fixes and rewordings.
  • Attunement adds: “If the prerequisite is to be a spellcaster, a creature quali- fies if it can cast at least one spell using its traits or features, not using a magic item or the like.”
  • Magic Weapons adds “If a magic weapon has the ammunition property, ammunition fired from it is considered magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.”. I’m not sure about you, but we were already playing this way.
  • Changes to the wording for poison too.
  • Recent printings of the book, starting with the third, include these changes.

From the Sage Advice article…

“Some errors slipped into the books, and we’ve fixed them in their most recent printings. The tremendous popularity of the books has made it possible for us to reprint and correct them. It’s normal in publishing to correct typos, omissions, and misstatements in later printings of a book. The corrections in the new printings of the MM and the DMG are of that sort. We have cut words that shouldn’t be there, added some that should have been there, and clarified some rules.”

“Most of the Monster Manual changes are minor math corrections that will rarely have a noticeable impact in play. We’ve included such changes in the document for the sake of thoroughness—to show what’s changed—not because we think DMs should fret about such tweaks. Few of the DMG corrections are likely to be noticed often in play either. Even the meatier corrections—such as the ones in the MM for legendary creatures or the one in the DMG about effects stacking—are within the DM’s purview to apply to a game. If you’ve been enjoying these books for the past year, we recommend paying attention only to the changes that will enhance your enjoyment.”
