Everything to Do in Act 3 BG3 Before Finishing the Story
Reaching Act 3 of Baldur's Gate 3 brings players into the bustling streets of Lower City, offering an overwhelming amount of content before the final confrontation. Navigating this vast urban expanse requires careful planning to ensure no crucial character arcs or powerful gear are left behind. Completing key side quests before triggering the point of no return ensures your party is fully prepared for the ultimate climax.
Conclude Companion Personal Quests
Act 3 serves as the grand stage for resolving the personal stories of your trusted companions. Visiting the Szarr Palace allows Astarion to confront his former master, while Shadowheart must face the House of Grief to settle her relationship with the Shar enclave. Guiding Gale through Sorcerous Sundries or helping Wyll resolve his pact with Mizora unlocks vital character resolutions and unique narrative outcomes.
Ignoring these companion storylines can result in permanent losses or missed allies during the final conflict. Resolving their conflicts provides powerful legendary equipment and grants significant experience points to maximize party potential. Taking the time to speak with each companion in camp will highlight which personal goals remain unfulfilled.
Rally Allies for the Final Battle
Throughout your journey across the Sword Coast, your choices determine who will answer your call during the Gather Your Allies questline. In Act 3, you can secure aid from faction leaders, rescued prisoners, and powerful figures like Nine-Fingers Keene or the Guild. Completing secondary quests for these groups unlocks unique summonable abilities during the final assault on the Brain.
Exploring every corner of the city helps you discover smaller factions that offer invaluable battlefield support. Rescuing Florrick from the prison cells or aiding the Gondians inside the Steel Watch Foundry secures strong allies for the end game. Ensuring these quests are marked off your log guarantees maximum tactical flexibility when the final campaign begins.
Disable the Steel Watch and Confront Gortash
Lord Enver Gortash maintains control over the city through his mechanical sentinels known as the Steel Watch. Infiltrating and destroying the Steel Watch Foundry dismantles his defense network and makes the fight against him significantly more manageable. Additionally, exploring the Iron Throne underwater prison allows you to save innocent hostages before the facility collapses.
Taking down the foundry before entering Wyrm's Rock Fortress alters the political dynamic of the city drastically. Defeating Gortash stripped of his ironclad defenders opens the pathway to collecting his Netherstone. This major step progresses the main narrative and clears the way for the ultimate showdown.
Explore Hidden Vaults and Obtain Legendary Gear
Act 3 is filled with secret chambers, complex puzzles, and formidable optional bosses guarding best-in-slot items. Venturing into the Wyrm'sway lets you solve dragon trials to wake Ansur and claim the Balduran's Giantslayer sword. Meanwhile, breaking into the Counting House vaults yields immense wealth and rare armor pieces for your martial characters.
Visiting Sorcerous Sundries grants access to forbidden vaults containing powerful magical scrolls and legendary robes for casters. Ensuring your party is equipped with top-tier gear dramatically increases your combat efficiency against late-game encounters. Taking time to thoroughly loot these locations prepares your team for any unexpected threats.
