How do I unlock the secret ending with the Illithid in Baldur's Gate 3?

To unlock the secret ending involving the Illithid in Baldur's Gate 3, you need to make specific choices throughout the game that align with the Illithid's influence and power. This ending is tied to the Mind Flayer parasite that infects your character at the beginning of the game. The key to achieving this ending lies in embracing the parasite's power rather than resisting it. Here is a detailed guide on how to achieve this ending, including mechanics, strategies, and tips.

First, it is important to understand the mechanics of the Illithid powers. Early in the game, you are infected with a Mind Flayer parasite. Throughout the story, you will encounter opportunities to use the parasite's powers, which are presented as dialogue options or abilities in combat. These powers are tied to the Illithid Wisdom skill, which increases as you use the parasite's abilities. To unlock the secret ending, you must consistently choose to use these powers and embrace the parasite's influence. This means selecting dialogue options that favor the Illithid, using Illithid powers in combat, and making story choices that align with the Mind Flayers' goals.

Step-by-step, you should start by using the Illithid powers whenever they are presented. This includes dialogue options that allow you to manipulate or intimidate others using the parasite's influence. For example, in Act 1, you can use the Illithid power to persuade the Goblin leaders to let you pass without a fight. In Act 2, you can use the parasite's power to dominate certain enemies or NPCs. Each time you use these powers, your Illithid Wisdom skill will increase, and you will unlock more powerful abilities. This progression is crucial for the secret ending.

Another important step is to avoid removing the parasite. Throughout the game, you will encounter opportunities to remove the parasite, such as through the help of certain NPCs or by completing specific quests. To achieve the secret ending, you must resist these opportunities and keep the parasite intact. This means turning down offers to remove the parasite and avoiding quests that lead to its removal. For example, in Act 2, you will meet a character who offers to remove the parasite. You must refuse this offer to stay on the path to the secret ending.

In addition to using the parasite's powers and keeping it intact, you must also make story choices that align with the Illithid's goals. This includes siding with the Mind Flayers in key moments and making decisions that further their agenda. For example, in Act 3, you will face a major decision that determines the fate of the Illithid. To unlock the secret ending, you must choose to side with the Mind Flayers and embrace their power. This decision will have significant consequences for the story and your character.

Important tips and considerations include managing your party's reactions to your choices. Some companions may disapprove of your use of Illithid powers, which can affect their loyalty and relationship with you. To mitigate this, you can focus on building relationships with companions who are more open to the use of such powers, such as Astarion or Lae'zel. Additionally, you should be mindful of the moral implications of your choices, as embracing the Illithid's power will lead to a darker and more morally ambiguous ending.

Common mistakes to avoid include removing the parasite or failing to use its powers consistently. If you remove the parasite at any point, you will lose access to the Illithid powers and be unable to achieve the secret ending. Similarly, if you do not use the parasite's powers enough, your Illithid Wisdom skill will not increase, and you will not unlock the necessary abilities for the ending. It is also important to avoid siding against the Mind Flayers in key moments, as this will prevent you from achieving the secret ending.

Advanced techniques and optimizations include focusing on character builds that complement the use of Illithid powers. For example, a character with high Charisma and Wisdom will be more effective at using the parasite's influence in dialogue and combat. Additionally, you can optimize your party composition to include companions who are more tolerant of the Illithid's power, allowing you to use these abilities without negative consequences.

In terms of D&D rules and mechanics, the Illithid powers in Baldur's Gate 3 are based on the Mind Flayer abilities from the Dungeons and Dragons 5th Edition ruleset. These abilities include mind control, psychic damage, and other effects that manipulate or dominate others. The game's implementation of these powers is consistent with the D&D rules, and understanding how they work in the tabletop game can help you use them more effectively in Baldur's Gate 3.

Specific examples and scenarios include using the Illithid power to dominate the Goblin leaders in Act 1, which allows you to bypass combat and gain their trust. In Act 2, you can use the parasite's power to control the mind of a key NPC, leading to a different outcome in the story. In Act 3, you will face a major decision that determines the fate of the Illithid, and choosing to embrace their power will lead to the secret ending.

In conclusion, unlocking the secret ending with the Illithid in Baldur's Gate 3 requires you to embrace the parasite's power, use its abilities consistently, and make story choices that align with the Mind Flayers' goals. By following these steps and avoiding common mistakes, you can achieve this unique and morally complex ending.
