What happens if I let the tadpole control the Netherbrain in Act 3 of Baldur's Gate 3?

In Baldur's Gate 3, allowing the tadpole to control the Netherbrain in Act 3 is one of the most significant and morally complex decisions you can make. This choice has far-reaching consequences for the story, your companions, and the world itself. To achieve this outcome, you must follow a specific path that involves embracing the power of the tadpole and making certain key decisions throughout the game. Here is a detailed explanation of how to achieve this ending, along with important tips and considerations.

First, it is important to understand the mechanics involved. The tadpole in your head is a parasitic entity that grants you psionic powers but also poses a significant threat to your autonomy. Throughout the game, you will encounter opportunities to either resist the tadpole's influence or embrace it. To allow the tadpole to control the Netherbrain, you must consistently choose options that align with the tadpole's agenda. This means using your psionic powers whenever possible, making decisions that prioritize power over morality, and siding with characters who encourage you to embrace the tadpole's potential.

The first step in this process is to use the tadpole's powers as often as you can. Early in the game, you will encounter situations where you can use your psionic abilities to influence others or gain an advantage in combat. Each time you use these powers, you strengthen the connection between yourself and the tadpole. This is crucial because the more you use the tadpole's powers, the more likely you are to unlock advanced abilities and dialogue options that will lead you down the path of allowing the tadpole to take control.

As you progress through the game, you will encounter key moments where you must make decisions that either resist or embrace the tadpole's influence. One of the most important moments occurs in Act 2, when you meet the Emperor, a powerful mind flayer who has been guiding you from the shadows. The Emperor will offer you the chance to fully embrace the tadpole's power by transforming into a mind flayer. To allow the tadpole to control the Netherbrain, you must accept this offer and undergo the transformation. This decision is irreversible and will significantly alter your character's abilities and appearance.

Once you have transformed into a mind flayer, you will gain access to powerful psionic abilities that can be used to dominate others and control the battlefield. These abilities are essential for the final confrontation with the Netherbrain in Act 3. During this confrontation, you will have the option to use your newfound powers to seize control of the Netherbrain and bend it to your will. This is the moment where you can allow the tadpole to take full control, effectively becoming the dominant force in the world.

There are several important tips and considerations to keep in mind when pursuing this path. First, it is crucial to build your character in a way that complements the tadpole's powers. Classes that rely on intelligence and charisma, such as wizards, sorcerers, and bards, are particularly well-suited for this playstyle. Additionally, you should prioritize feats and abilities that enhance your psionic powers, such as the Telekinetic feat or the Psionic Soul subclass for sorcerers.

Another important consideration is the impact this path will have on your companions. Many of your companions will be deeply disturbed by your decision to embrace the tadpole's power, and some may even leave your party if you go too far down this path. It is important to manage your relationships carefully and choose companions who are more likely to support your decisions, such as Astarion or Lae'zel.

Common mistakes to avoid include resisting the tadpole's influence at key moments or failing to use your psionic powers consistently. If you do not fully commit to the tadpole's agenda, you may miss out on the opportunity to allow it to control the Netherbrain. Additionally, it is important to avoid making decisions that alienate your companions, as this can make the final confrontation more difficult.

Advanced techniques and optimizations include using your psionic powers to manipulate key NPCs and gain their support. For example, you can use your powers to persuade the Githyanki to ally with you, or to convince the Emperor to reveal more about the tadpole's true nature. These interactions can provide valuable insights and resources that will aid you in your quest to control the Netherbrain.

In terms of related D&D rules and mechanics, the tadpole's powers are based on the psionic abilities found in the Dungeons and Dragons 5th Edition ruleset. These abilities allow you to manipulate the minds of others, telekinetically move objects, and even dominate the will of powerful creatures. Understanding how these abilities work in the context of the game can help you make the most of your psionic powers and achieve your goals.

Specific examples and scenarios include using your powers to dominate the mind of a powerful enemy during a critical battle, or using telekinesis to manipulate the environment and gain a tactical advantage. In one scenario, you might use your powers to convince a group of hostile NPCs to stand down, avoiding a potentially deadly confrontation. In another, you might use your abilities to uncover hidden information that will help you in your quest to control the Netherbrain.

In conclusion, allowing the tadpole to control the Netherbrain in Act 3 of Baldur's Gate 3 is a complex and morally ambiguous path that requires careful planning and strategic decision-making. By consistently using your psionic powers, making key decisions that align with the tadpole's agenda, and managing your relationships with your companions, you can achieve this unique and powerful ending.
