Wizards of the Coast is testing a Dungeons & Dragons tabletop option that lets player characters gradually transform into mind flayers, mirroring the "ceremorphosis" storyline from the video game Baldur's Gate 3. The new "Path of Ceremorphosis" appeared in an Unearthed Arcana playtest document released on Thursday alongside other Underdark-themed aberrant subclass options for Barbarians, Rogues and Wizards, and the publisher has explicitly credited the character Tav's arc in Baldur's Gate 3 as an influence.

The path begins at level 4 with the Tadpole Host feat, granting psionic abilities such as Mind Sliver, before players can pick up mid-level feats including Illithid Thrallmaker, Tadpole's Safeguard and Ulitharid's Might. At level 12, the Full Ceremorphosis feat completes the change into a purple, tentacle-faced Aberration, letting players specialise in mind flayer spells like Detect Thoughts and Mind Blast, or in physical Brain-Seeking Tentacles attacks, with the option to eventually take both.
