Yes, there are multiple consequences for using the Illithid powers in BG3. As you use them within your party, some of your allies like Lae’zel might oppose it. On the other hand, some allies like Astarion and Gale will support you in using these powers.

But if you continue using them and unlock more Illithid powers, there are mainly three consequences. These are as follows:

Half Mindlflayer Transformation

Once you unlock all the Tier 1 Illithid powers, the Guardian will reward you with an Astral-touched tadpole. If you chose to consume it, this will complete your transformation as a half-Illithid and unlock more Illithid powers.

Full Mindflayer Evolution

Entering the endgame content, you will receive the Supreme Tadpole from the Guardian that unlocks the last tier and all the Illithid powers. If you choose to consume the parasite, it will complete your Illithid evolution and transform you into a full Mind Flayer with free will. Further, you will also get upgraded Illithid powers offering enhanced buffs and immunity.


Once you transform into a full Mindflayer, it will have an impact on the ending of Baldur’s Gate 3. As you destroy the Netherbrain and the swarms of Illithids, you will free your allies and yourself from the influence of the Parasite stuck in your head. But due to your evolution, you don’t remember anything about your former self.
