The central antagonism in the critically-acclaimed Baldur’s Gate 3 is driven by the entity called the Netherbrain. A cursory glance at the game's lore may suggest that this Netherbrain is not as intellectually capable as it could be.
The Netherbrain serves as the mastermind behind the complex matrix of troubles that the characters face. Without the Netherbrain, the Dead Three would still be plotting to rule the Sword Coast, the Githyanki would still be subjected to a fascist regime. However, these challenges would be significantly more manageable if not for the ordeal of having a tadpole buried deep inside their brains.
The Netherbrain is more than just an Elder Brain, it is also empowered by the crown of Karsus. This gives it an immense power level, making it a formidable foe who is capable of conquering the world. The game dedicates large portions of its narrative describing the immense strength of Elder Brains. Indeed, it is only due to the powers of Orpheus and the benevolence of the Emperor that survival against the Netherbrain's influence is even viable.
Players familiar with Gale’s storyline or those who have listened to Raphael’s proposition in the third act would be aware of the true extent of the crown of Karsus's power. The crown can elevate Gale to godhood and it is fair to conjecture that an Elder Brain wielding such power could be invincible.
Rethinking the Netherbrain's Capabilities
The portrayal of the Netherbrain creates a dichotomy between the game play requirements and the lore of Baldur’s Gate 3. It wouldn't deliver a satisfying experience for players if the Netherbrain were to eliminate their entire party at the start of the boss fight, even though logically, its power level suggests that it could do so.
This struggle between the Netherbrain's theoretical and actual power isn't lost on players. Many have noticed that the Netherbrain isn't as intellectually superior as a lore-friendly interpretation would suggest.
As one player insightfully remarked, “The supreme intellect of a Nether Brain is nothing compared to a story’s need for the plot to get to the end.”
The Necessity of Power Restraint
From a gameplay perspective, it is essential that a balance is struck between staying true to lore and maintaining manageable challenges that are simultaneously engaging and not drastically skewed against the player.
While the lore suggests that the Netherbrain, with its ultra high intelligence and its possession of the crown of Karsus, should be practically invincible, this would create insurmountable challenges for players and compromise the gameplay experience.
In conclusion, while the Netherbrain's colossal power has been curtailed to facilitate a balanced and engaging gameplay, it continues to pose a thrilling challenge to be overcome by players in Baldur's Gate 3.
