Act Three of Baldur’s Gate 3 is where Baldur’s Gate 3 truly starts to open up, as you are bombarded with different quests from the second you arrive in Rivington. And there are plenty of main quests, story quests, personal quests, and side quests to do.
Every Act 3 quest in Baldur’s Gate 3
This BG3 quest list will encompass both main and side quests that either start in Act Three or are progressed or completed in one of the maps you visit. You might see some quests you received in Acts One or Two, but they are on this list because they finish at some point in Act 3.
In Act Three, many of the quests you started in previous acts culminate. The events at Moonrise Towers lead to several different branching questlines; characters you met previously have made their way to the city and still need your help, and there are new characters who want to meet the companions you’ve picked up along your travels.
