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 start of the game, and it requires you to embrace the powers and choices that come with 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, which grants you access to unique abilities. These abilities are tied to the Illithid Wisdom skill, which allows you to influence others and make decisions that align with the Mind Flayer's agenda. To unlock the secret ending, you must consistently choose to use these powers and make decisions that favor the Illithid. This means embracing the parasite rather than resisting it.

Step-by-step, you should start by using the Illithid Wisdom skill whenever it appears in dialogue options. This will increase your connection to the parasite and open up new paths in the story. For example, in Act 1, when you encounter the dying Mind Flayer on the Nautiloid ship, choose to interact with it using your Illithid powers. This sets the tone for your character's willingness to embrace the parasite. Throughout the game, you will encounter other characters who are also infected, such as the Dream Visitor. When interacting with them, always choose options that align with the Illithid's goals.

In Act 2, you will face a critical decision involving the Nightsong. To unlock the secret ending, you must side with the Absolute and the Illithid forces. This means choosing to sacrifice the Nightsong to the Absolute, which strengthens your connection to the parasite. This decision will have significant consequences for the story and your companions, so be prepared for potential conflicts with party members who oppose the Illithid.

Act 3 is where the final steps to unlock the secret ending take place. You will encounter the Elder Brain, and at this point, you must fully embrace the Illithid's power. This involves using your Illithid abilities to dominate the Elder Brain and take control of its power. To do this, you need to have consistently used your Illithid powers throughout the game and made choices that align with the Mind Flayer's agenda. If you have done this correctly, you will have the option to dominate the Elder Brain and become the new Illithid overlord, leading to the secret ending.

Important tips and considerations include managing your party's reactions to your choices. Some companions, like Lae'zel and Shadowheart, may oppose your decisions to embrace the Illithid. To avoid losing them, you need to carefully manage your relationships and persuade them to support your path. Additionally, make sure to invest in skills and abilities that enhance your Illithid powers, such as Wisdom and Charisma, as these will be crucial in key moments.

Common mistakes to avoid include resisting the Illithid powers or making choices that weaken your connection to the parasite. For example, if you choose to remove the parasite or side against the Absolute, you will not be able to unlock the secret ending. It is also important to avoid alienating key characters who can help you achieve this ending, such as the Dream Visitor.

Advanced techniques involve optimizing your character build to maximize the effectiveness of your Illithid powers. This includes choosing a class that benefits from high Wisdom and Charisma, such as a Sorcerer or Cleric. You should also focus on acquiring items and equipment that enhance your Illithid abilities, such as the Mind Flayer Parasite Specimen, which can be found in specific locations throughout the game.

In terms of D&D rules and mechanics, the Illithid powers in Baldur's Gate 3 are based on the Mind Flayer's abilities in the 5th Edition rules. These include telepathy, mind control, and psychic damage. Understanding these rules can help you make better use of your powers in the game. For example, using telepathy to communicate with NPCs can open up new dialogue options and story paths.

Specific examples and scenarios include the encounter with the Githyanki in Act 1. When you meet the Githyanki patrol, use your Illithid powers to assert dominance and avoid conflict. This not only strengthens your connection to the parasite but also sets the stage for future interactions with the Githyanki. Another example is the confrontation with Ketheric Thorm in Act 2. Use your Illithid powers to manipulate the situation and ensure that you are in a position to dominate the Elder Brain later in the game.

In conclusion, unlocking the secret ending with the Illithid in Baldur's Gate 3 requires a consistent and deliberate approach to embracing the Mind Flayer's power. By using your Illithid abilities, making choices that align with the parasite's agenda, and managing your relationships with key characters, you can achieve this unique and powerful ending.
