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 storyline, which revolves around the parasite in your character's head and the potential to embrace or resist its power. 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 storyline. Early in the game, your character is infected with a Mind Flayer parasite. This parasite grants you access to Illithid powers, which can be used in dialogue and combat. However, using these powers increases your connection to the parasite and the Illithid collective. To unlock the secret ending, you must fully embrace this connection by consistently choosing options that enhance your Illithid powers and align with the Mind Flayer agenda.

Step-by-step, you should start by using Illithid powers whenever they are offered in dialogue or combat. These choices will often present themselves as unique dialogue options marked with a special icon. For example, during conversations with NPCs, you may have the option to use your Illithid powers to persuade, intimidate, or manipulate them. Choosing these options will increase your connection to the parasite and move you closer to the secret ending.

As you progress through the game, you will encounter key moments where you must make significant choices that impact your relationship with the Illithid. One such moment occurs when you meet the Dream Visitor, a mysterious figure who appears in your dreams. The Dream Visitor will offer you guidance and encourage you to use your Illithid powers. To unlock the secret ending, you should follow their advice and continue to embrace the parasite's influence.

Another critical moment comes when you reach the Underdark and encounter the Mind Flayer colony. Here, you will have the opportunity to interact with the Illithid directly. Choosing to cooperate with them and further integrate the parasite into your being is essential for unlocking the secret ending. This may involve making morally ambiguous decisions, such as sacrificing allies or allowing the Illithid to experiment on you.

Throughout the game, you should also prioritize upgrading your Illithid powers. This can be done by consuming special items called Tadpoles, which are found in various locations or obtained by defeating certain enemies. Each Tadpole you consume will grant you new abilities and strengthen your connection to the Illithid. Be sure to use these powers frequently in combat and dialogue to maximize their impact.

Important tips and considerations include being mindful of your companions' reactions. Some companions may disapprove of your choices to embrace the Illithid powers, which can affect your relationships with them. To mitigate this, you can focus on building relationships with companions who are more open to the use of Illithid powers, such as Astarion or Lae'zel. Additionally, you should avoid actions that would sever your connection to the Illithid, such as seeking a cure for the parasite or resisting its influence at key moments.

Common mistakes to avoid include neglecting to use Illithid powers when they are available. Each time you choose not to use these powers, you miss an opportunity to strengthen your connection to the Illithid. Another mistake is failing to consume Tadpoles, as this will limit your access to powerful abilities and slow your progress toward the secret ending.

Advanced techniques involve optimizing your character build to make the most of your Illithid powers. For example, choosing a class that benefits from high Intelligence, such as a Wizard or Sorcerer, can enhance the effectiveness of your Illithid abilities. Additionally, focusing on skills like Persuasion and Intimidation can make it easier to succeed in Illithid-related dialogue checks.

In terms of D&D rules and mechanics, the Illithid powers in Baldur's Gate 3 are inspired by the Mind Flayer abilities found in the Dungeons and Dragons 5th Edition rule set. These include powers like Mind Blast, which deals psychic damage and stuns enemies, and Dominate Person, which allows you to control an enemy's actions. Understanding these abilities and how they function in the context of D&D can help you use them more effectively in the game.

Specific examples and scenarios include the encounter with the Githyanki patrol in Act 1. Here, you can use your Illithid powers to avoid combat and gain valuable information. Another example is the confrontation with the Absolute's followers in Act 2, where using Illithid powers can help you manipulate the situation to your advantage.

By following these steps and strategies, you can unlock the secret ending with the Illithid in Baldur's Gate 3. This ending offers a unique and morally complex conclusion to the game, showcasing the consequences of fully embracing the power of the Mind Flayer parasite.
