BG3 Act 2 Tips: Shadow Curse, Last Light Inn and Moonrise

The most useful Act 2 tips in Baldur's Gate 3 are to keep a light source on every character, get Isobel's Blessing of Selûne at the Last Light Inn, and finish your business at the inn before you talk to Isobel, because that conversation starts a fight that can destroy the inn. Visit Moonrise Towers before you go deep into the Gauntlet of Shar, start Halsin's quest to lift the curse early, and bring Shadowheart along for the Nightsong.

Spoilers here are limited to quest names, places and the risks you face. Story outcomes are only described where you need them to avoid losing content.

Before you leave Act 1

There are two ways into the Shadow-Cursed Lands: the Mountain Pass, via the Rosymorn Monastery Trail, or the Underdark, via the elevator in Grymforge. Heading there before the Emerald Grove conflict is resolved closes it automatically, and most quests tied to the tieflings and the goblins end with it. You can still return to the rest of the Act 1 map later, so other loose ends can wait. The Act 1 tips list what to finish first.

How to survive the Shadow Curse

The land in Act 2 is cursed. Anyone standing in the dark without protection takes necrotic damage that gets worse every turn they stay there, and a character who drops to zero hit points while cursed is in serious trouble. You will be offered torches as you arrive, and you should take them.

The dense areas are the problem. In those, ordinary light is snuffed out and only a Moonlantern or the Pixie Blessing keeps you safe. If you meet the drider convoy, decide early how you will get that lantern, since freeing the pixie inside it is the easiest way to explore everywhere.

Shadowheart has her own protection in the lighter areas, but it does not help in the dense ones.

Last Light Inn: what to do first

The Last Light Inn is the safe hub of Act 2. It is protected by a barrier kept up by Isobel, a cleric of Selûne, and it is where you find Jaheira, the Harpers and, if you saved them, the tiefling refugees and their traders. Use it like a town:

• Shop, sell and talk to everyone before you do anything else.
• Pick up the side quests that start here.
• Visit Art Cullagh, an unconscious man in a room on the ground floor. He is the key to Halsin's quest (see below).

Only then go upstairs to Isobel.

The fight with Marcus

Talking to Isobel triggers a story event. A winged Flaming Fist called Marcus arrives to take her, and if you side with Isobel he calls in a flock of winged monsters. This fight is on a clock: they ignore your party and go straight for Isobel.

If Isobel is captured or killed, the inn falls. Its barrier fails, the curse sweeps in, and nearly everyone inside is killed or turned, including merchants and quest givers. To avoid that:

1. Rest and prepare before you talk to her, with full spell slots and your strongest party.
2. Put all your damage into Marcus from the first turn. He is the main threat to Isobel.
3. Use crowd control and area attacks on his summons when you can, but keep Isobel out of your own blast radius.
4. Heal and buff Isobel only once Marcus is under pressure, since healing alone will not keep up with his attacks.

Save before the conversation. If it goes badly, reloading is far better than losing the hub for the rest of the act.

Visit Moonrise Towers before the Gauntlet of Shar

Moonrise Towers is the Absolute's base and the centre of the act's main quest. You can walk in posing as True Souls, the Absolute's chosen followers, which opens many quests and conversations you would otherwise miss.

Order matters here. Inside the Gauntlet of Shar, entering the Shadowfell is Act 2's point of no return: after it, you can no longer travel back to the Act 1 map, and any unfinished quests there end automatically, usually failed. If you have not visited Moonrise Towers before that point, a lot of its content is also resolved for you. So the safe order is:

1. Finish anything left in the Act 1 areas.
2. Visit Moonrise Towers and work through what you can there.
3. Then go deep into the Gauntlet of Shar.

At Moonrise you will also find prisoners, including tieflings from the Emerald Grove, who need help to escape, and a decision about Minthara's fate if you knocked her out in Act 1. Saving her this way is how she joins your party.

Start Halsin's quest early

If you rescued Halsin and beat the goblin leaders in Act 1, he travels with you to help lift the Shadow Curse. Ask him about it at camp to begin Lift the Shadow Curse. The quest runs through several steps:

• Find Art Cullagh at the Last Light Inn and wake him, using a lute you find in the House of Healing in Reithwin Town.
• Bring Halsin to him, then follow Halsin to the lakeshore and defend the portal he opens into the Shadowfell for several rounds while he is inside.
• Track down the missing half of the land's spirit, then defeat Ketheric Thorm to finish the job.

Completing it matters beyond Act 2. Halsin only joins your party once Thaniel is rescued and made whole, and he stays for good only if the curse is lifted before you leave for Baldur's Gate. Otherwise he stays behind. His romance also depends on it, as the romance guide explains.

The Gauntlet of Shar and the Nightsong

The Gauntlet of Shar is the act's big dungeon, full of puzzles and fights. To reach the final chamber you need the Spear of Night from the Silent Library and all four umbral gems found inside the Gauntlet.

The quest Find the Nightsong ends here with a major choice that shapes Shadowheart's story. Bring her with you, and save before the last chamber so you can think the choice through.

Resting and companions in Act 2

• Take long rests. Act 2 has a lot of camp scenes, and some romances move forward here. Gale's relationship, for example, can only become serious after you reach Moonrise Towers and before you enter the Mind Flayer Colony.
• Recruit the new companions. Jaheira can join if she survives the assault on Moonrise, and Minthara joins through the choice at Moonrise mentioned above. The companion guide covers their roles.
• Don't rush the ending. The act's final stretch starts once you confront Ketheric Thorm at the top of Moonrise Towers, which leads into the Mind Flayer Colony. Treat that as the end of Act 2 and finish everything else first.

Frequently asked questions

How do you get past the Shadow Curse in BG3?

Carry a torch or other light in the lighter areas, and get Isobel's Blessing of Selûne at the Last Light Inn so the whole party is covered there. In the dense areas you need a Moonlantern or the Pixie Blessing, which you get by freeing the pixie in Kar'niss's lantern.

What happens if Isobel dies or is captured?

The Last Light Inn loses its protection and the curse overruns it. Almost everyone inside is killed or transformed, including traders and quest givers, so protect her by focusing all your attacks on Marcus.

What is the point of no return in Act 2?

Entering the Shadowfell inside the Gauntlet of Shar. After that, you cannot return to the Act 1 map and unfinished quests there end. Visit Moonrise Towers before this point as well, or much of its content resolves without you.

Should I go to Moonrise Towers or the Gauntlet of Shar first?

Moonrise Towers. Visiting it first keeps its quests open, and the Gauntlet's Shadowfell entrance closes off the Act 1 areas, so it makes sense to tie up those loose ends before you go deep into the Gauntlet.

How do you recruit Halsin permanently in Act 2?

Complete Lift the Shadow Curse. Halsin joins the party after you rescue Thaniel and reunite him with his missing half, and he becomes a permanent companion once Ketheric Thorm is defeated and the curse is lifted. If you leave for Baldur's Gate without finishing it, he stays behind.

Can you go back to Act 1 areas from Act 2?

Yes, until you enter the Shadowfell inside the Gauntlet of Shar. Before that point you can travel back to the Act 1 map to finish quests, except for those tied to the Emerald Grove conflict, which closed when you left.
