Key Takeaway

Illithid Powers are linked to the Tadpole in the main character and Companion’s heads. After using the Illithid dialogue options a few times, you’ll be visited by a stranger in your dreams who will explain how to harness your mind flayer powers.

As you explore the world of Baldur’s Gate 3, you’ll come across Tadpoles. Each of these can be used to unlock new abilities on the Illithid Powers skill tree. Accepting these Powers may upset some of your Companions, but doing so can greatly help you in battle.

Baldur’s Gate 3 allows players and their companions to tap into unique Illithid powers during their playthrough. As powerful as they may be, it can be nerve-wracking to welcome even more mind flayer parasites into your already-infected brain. What are the consequences of unlocking these abilities?

    What Are Illithid Powers?

    Illithid Powers are special abilities linked to the mind flayer tadpole implanted in the heads of the main character and their Companions at the start of Baldur’s Gate 3. Also called Tadpole Powers, these unique capabilities can greatly increase your character’s survivability during your playthrough.

    There are many kinds of Illithid Powers, ranging from additional healing abilities and increased damage against enemies to bonuses to Ability Checks. Stronger Powers include the ability to fly and the removal of resource costs for actions or spells.

    How to Unlock Illithid Powers

    As you interact with other characters, you’ll occasionally be offered an Illithid dialogue option. After selecting this option and successfully passing the relevant Ability Skill checks a few times, you’ll meet a peculiar stranger in your dreams. This Dream Visitor gives you the option to tap into your Illithid Powers, explaining that to unleash your full potential, you’ll need to find other Tadpoles on your journey.

    The Illithid Power skill tree can be accessed by clicking the Tadpole icon at the top right of your screen. Each Illithid Power costs one Tadpole to unlock, and these slimy creatures can be obtained by finding them around the world or by defeating infected enemies.

    Some Illithid Skills can only be unlocked by fulfilling a certain prerequisite. All Skills, however, are available to all races and classes. Each infected Companion will have their own Skill Tree, allowing you to prioritize different Skills for different characters.

    About the Astral-Touched Tadpole

    At the start of Act 3, your camp will be assaulted by Githyanki warriors as you sleep. You’ll be given three turns to reach a portal leading you to safety. Failing to do so will result in your full transformation into a mind flayer, which isn’t ideal.

    Once inside the portal, you’ll need to defeat four Githyanki warriors to keep the Absolute at bay. Following this, you’ll be given the Astral-Touched Tadpole, which gives your Illithid Powers a major boost.

    Choosing to open your mind to the Tadpole will unlock the final tier of Illithid Powers and will automatically unlock every power in the first tier, including the ability to fly. It also makes it possible for you to convince your Companions to accept the change. Some will be more receptive than others.

    Warning
    Opening your mind to the Astral-Touched Tadpole will also cause your character’s face to be permanently marred by black veins. If you’re focused on cosmetics, tread carefully.

    If you’re feeling greedy, you can choose to eat the Tadpole. This will have the same effect on your character as opening your mind to it, but you’ll be unable to offer it to your Companions.

    If you’re struggling with this major decision and want more time to ponder, you can choose to refuse the Tadpole. This will add it to your inventory, allowing you to freely make your choice later. If you’re adamant about your decision not to accept this boon, you can stomp on the Tadpole.

    Should You Use Illithid Powers in Baldur’s Gate 3?

    Unlocking Illithid powers in Baldur’s Gate 3 isn’t mandatory, and the decision to do so is completely up to you. Even if you collect a sizeable amount of Tadpoles, you’re not obligated to use them. If your character is focused on being a good person, aligning yourself with a mind flayer might be a tough sell from a roleplaying perspective.

    For many, the most frightening part of accepting Illithid Powers is the possibility of transforming into a mind flayer yourself. Fortunately, it’s easy to avoid this by disobeying any orders aligning with the Absolutist’s goals, regardless of how many Powers you’ve unlocked.

    If you’re not afraid to experiment with the dark side, tapping into Illithid Powers can make you more powerful and reveal a unique side of Baldur’s Gate 3‘s story. When pairing these abilities with your character’s Skills and Feats, they can quickly become a critical part of your arsenal.
