Players can get Illithid Powers by finding and consuming Illithid Parasites. These parasites can be found all throughout the game through looting corpses or drops from defeating enemies.
All Illithid Parasite Locations
Upon seeing the Illithid Powers screen for the first time, there are only 15 available nodes to select. Players can expand these by collecting more parasites in the game.
In order to unlock the 3rd Layer of Illithid Powers, players will need to reach the end of Act 2 and obtain the Astral-Touched Tadpole. Once obtained, you can consume or resonate with it to unlock the final set of Illithid Powers for purchase.
