BG3 What to Do Before Shadowfell: Important Tasks and Choices

Navigating the central storyline of Act 2 in Baldur's Gate 3 eventually brings players to the pool inside the Gauntlet of Shar, which leads into the Shadowfell. Reaching this area prompts a clear warning on screen because stepping through the pool creates a major point of no return for the entire region. Understanding which quests, interactions, and exploration tasks must be finished beforehand ensures that you do not lose out on valuable rewards or companion story progression.
Rescuing Prisoners and Exploring Moonrise Towers
Before entering the Shadowfell realm, infiltrating Moonrise Towers peacefully should be your top priority. Visiting the prison beneath the fortress allows players to rescue key allies like Wulbren Bongle and the captured tieflings before the tower turns fully hostile. Leaving these characters in their cells before proceeding into the pool will result in their untimely deaths.
Moonrise Towers also features unique vendors offering powerful magic items and crafting components that become unavailable once the story advances. Be sure to browse their inventories and complete social interactions, such as bringing Astarion to meet the drow alchemist Araj Oblodra for a permanent strength boost. Taking care of these tasks first guarantees you gain every tactical edge available for upcoming Act 2 boss battles.
Lifting the Shadow Curse with Halsin
Another crucial objective to resolve before stepping into the Shadowfell is helping Halsin heal the surrounding blighted lands. This involves waking Art Cullagh at Last Light Inn using the battered lute retrieved from the House of Healing. Following this encounter leads to a defensive encounter on the shoreline where you must protect Halsin's portal while he searches for Thaniel.
Completing this quest line allows Halsin to officially join your party as a playable companion for future adventures. If you step into the Shadowfell before finding Thaniel and uniting him with Oliver, the shadow curse will remain unbroken forever. Ensuring this storyline is resolved keeps your companion options open and brings a satisfying resolution to the environmental narrative.
Clearing Act 1 Side Regions and Companion Threads
Entering the Shadowfell permanently closes the pathways back to Act 1 locations, including the Wilderness, the Underdark, and the Mountain Pass. If you have lingering objectives like resolving the Rosymorn Monastery secrets or retrieving the Blood of Lathander, clear them out now. Once the pool event triggers, any unfinished Act 1 content will automatically fail or become completely inaccessible.
It is also essential to resolve personal quests for your party members to avoid broken romances or permanent companion departures. Speak with Raphael outside the Grand Mausoleum to progress Astarion's personal quest regarding his fiendish scars. Taking these steps prepares your entire group for the dramatic events and severe choices waiting inside the Shadowfell realm.
