Act 3 of Baldur's Gate 3 presents the culmination of your journey, bringing you to the sprawling city of Baldur's Gate itself. The main quests in this act revolve around confronting the Elder Brain, securing the remaining Netherstones from the formidable leaders of the Lower City and Upper City, and ultimately deciding the fate of the Sword Coast. These quests are complex, multi-faceted, and often involve significant moral choices that will shape the ending of your game.
Confront the Elder Brain
The ultimate antagonist, the Elder Brain, is the source of the Mind Flayer tadpole infestation. Your primary objective is to find a way to stop it. This involves several sub-quests:
- Get Gortash's Netherstone: You must confront Lord Enver Gortash, the Lord of the City, who wields one of the Netherstones. This questline often involves dealing with the Steel Watch and navigating the political landscape of the Upper City. Key steps include Disable the Steel Watch and potentially Consider Gortash's Bargain.
- Get Orin's Netherstone: You also need to face Orin the Red, the leader of the Bhaal cultists, who holds another Netherstone. This quest involves investigating a series of murders, impressing the Murder Tribunal, and ultimately confronting Orin. Key steps include Investigate the Murders and Rescue Orin's Victim.
- Control the Elder Brain or Destroy the Elder Brain: Once you have the necessary Netherstones, you will have the option to either control the Elder Brain for your own ends or destroy it entirely, leading to different endgame scenarios.
Gather Your Allies
As the final confrontation approaches, rallying allies from across your journey becomes crucial. This questline involves revisiting characters and factions you've encountered throughout Acts 1 and 2, convincing them to join your cause. The success of this quest can significantly impact the final battle and the epilogue of the game.
Travel to Moonrise Towers
While technically a transition point that occurs at the end of Act 2, the journey to Moonrise Towers is a significant undertaking that sets the stage for Act 3. It involves navigating dangerous territories and making critical decisions about how to approach the Shadow-Cursed Lands. The path you choose, whether through the Mountain Pass or the Underdark, can have lasting consequences.
Key Decisions and Consequences
Act 3 is defined by the weight of your choices. The fate of Baldur's Gate, your companions, and the entire Sword Coast rests on your shoulders. Be prepared for intricate questlines, challenging boss fights, and narrative outcomes that are deeply tied to your actions throughout the entire game.
