Illithid powers are special abilities tied to the mind flayer tadpole that the player character, Origin, and some non-Origin companions are infected with.
Overview
Once attempting to cross the bridge leading to the Goblin Camp in Act One, a cutscene involving the Mysterious Artefact will trigger. During the next Long Rest, they will be visited by the Dream Guardian who encourages the player character to accept and wield the power the tadpole gives. This dream starts the Embrace Your Potential quest and enables the party to consume tadpoles in exchange for illithid powers.
Once the quest has started, consuming Mind Flayer Parasite Specimens, such as from the corpses of other infected, will allow the party members to unlock new powers.
- Gale and Astarion are willing to use illithid powers, no roll required.
- Karlach, Wyll, Lae'zel, and Shadowheart will initially refuse to use illithid powers, but can be convinced to use them through Persuasion checks. The opportunity to convince these party members to partake in illithid powers will be provided again in early Act Three, if they remain reluctant early on.
- Minthara already has consumed at least one Mind Flayer Parasite Specimen before the party met her, and because of this she already has some illithid powers upon being recruited (Charm, Concentrated Blast, Favourable Beginnings and Psionic Backlash).
- Halsin, Jaheira, and the Hirelings cannot get illithid powers.

Spellcasting ability modifier
Some illithid powers involve saving throws. For these powers, the difficulty class is determined by your spellcasting ability modifier, even for classes that do not typically have spells. All bonuses to spell save DC such as Arcane Acuity or Arcane Enchantment will also apply to illithid powers.
In the case of a multiclass, the ability score used by this modifier is determined by the latest class added to the multiclass. In other words, taking level 1 in a new class will switch the spellcasting ability modifier used by illthid powers (and items or scrolls) to use the new class's modifier.
Pre-release powers
This article is about gameplay elements – such as characters, quests or mechanics – that have been removed from the game and are no longer available. |
In Early Access, illithid powers were much simpler. Instead of consuming other tadpoles to gain points to spend on powers, your tadpole grew more powerful as you used Illithid Persuasion options in dialogue. Once you'd used Illithid Persuasion three times, a special cutscene was triggered during your next long rest and each character gained a single illithid power unique to their class. Some of these abilities were reworked into the current illithid powers. A full list of Early Access powers can be seen below:
