Sage Advice is a monthly column that gives official clarifications of D&D rules. Sometimes it also provides reference documents to help your D&D game run smoothly. Despite its official status, Sage Advice doesn’t trump the rulings of a Dungeon Master; the answers and information provided here are meant to assist a DM in adjudicating the game.

If you have questions for a future installment of Sage Advice, please send them to, or reach me on Twitter (@JeremyECrawford), where I answer questions between installments of this column.


Earlier this year, we released the Player’s Handbook errata document to correct and clarify some things in that book. Now we’re releasing similar documents for the Monster Manual and the Dungeon Master’s Guide.

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.

If you’re interested in seeing what’s changed and already have a copy of the MM and the DMG, we have prepared two short PDFs that list changes to each book (not including minor typo corrections):

Monster Manual Errata

Dungeon Master’s Guide Errata

You have a book that includes these corrections if its credits page bears the following text toward the bottom of that page: “This printing includes corrections to the first printing.”

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.

Sage Advice Compendium

If you’re wondering how we choose what to correct, see the Sage Advice Compendium (version 1.05), which addresses that question. The compendium has also been updated to account for the existence of the new errata.

Basic Rules

The Basic Rules PDF for DMs has been updated in accordance with the errata:
