D&D just put Baldur’s Gate 3’s nastiest idea in Unearthed Arcana: become the mind flayer.

Baldur’s Gate 3 let you flirt with a tadpole and then asked if you were still the person who opened the game. Players broke the internet arguing about it. This week’s Unearthed Arcana does the unromantic follow-up: it puts rules on the table for becoming a mind flayer on purpose. Not as a cutscene. As a progression.

That is a bigger deal than another subclass. D&D’s fifth-edition brain has spent a decade making sure your character stays a recognizable action figure. You get cooler. You do not get replaced. Ceremorphosis is the opposite fantasy. It is a promised power spike that eats your name.

The scary part is not the tentacles. It is that Wizards made the corruption feel like an upgrade path.

I like that they are testing it in the open instead of hiding it in a novel. Tables have been homebrewing this since the game launched. Giving it official levers - what you keep, what you lose, when the party is allowed to stop you - is how you keep the idea from becoming a one-session gimmick or a grief tool.

My request to the playtesters is simple: make the cost ugly enough that taking the power feels like a decision, not a feat tax. If the illithid track is just a stronger warlock with a new head, they have missed the only reason the idea ever worked. You should be able to win the fight and lose the person.
