Players Handbook 2024 Artificer. While no official announcement has been made regarding the artificer class, the recent posts regarding the 2024 phb mention: Dungeons and dragons to receive a rules update in 2024, with the player's handbook being the first to be released.
The 2024 versions of most artificer spells have been reworked, often completely changing how those spells function. In today’s one d&d video, jeremy crawford says there will be 48 subclasses in the ua, 4 for each of the 12 classes coming in the 2024 phb, confirming the artificer will not be in it.
