Why 2025’s Monster Manual Is Different

There are many reasons why theMonster Manualhas seen changes in 2025.Some of them are as simple as correcting inaccuraciesin previous versions: for example, the switch from “Poisonous Snake” to “Venomous Snake” is simply a matter of semantic accuracy. Others are for the sake of consistency, clarity, or simplicity, like the addition of the Modron prefix to the various drone enemies in the table above. Others have to do with certain types of monsters getting new, harder variants in the 2025 edition, hence the change from Azer to Azer Sentinel, for example.

“That Blob Is My Baby”: D&D’s Jeremy Crawford Talks The 2025 Monster Manual

Screen Rant sat down with lead designer Jeremy Crawford to discuss what’s in D&D’s 2025 Monster Manual and the upcoming slate of releases.

Many of theseMMsubstitutions also stem fromDnD’s attempt to leave the concept of inherently evil species and cultures behind. That’s apparent in the changes to monsters who come from playable races: Drow, for example, is substituted with the more generic Priest Acolyte, which has a standard humanoid statblock and can be subbed in for a character of any race. Other monster names have been changed to remove negative associations with indigenous people, like the change from Orc War Chief to Tough Boss or Lizardfolk Shaman to Lizardfolk Geomancer.

Some changes were made to remove gendered language, replacing Lizard King/Queen with Lizardfolk Sovereign, or Androsphinx and Gynosphinx with Sphinx of Valor and Sphinx of Lore, respectively. But whether they were changed to remove a bias or increase accuracy, they all serve to make theMonster Manualmore adaptable. That makes it a much more useful resource to anyDungeons & Dragonscampaign.
