You’ve probably spent hours wandering around the Shadow-Cursed Lands, watching your torch flicker while those creepy shadows jump out of the woodpipe. It’s oppressive. Honestly, the first time I realized I couldn't just "bless" the land away with a simple spell, I felt a bit cheated. But that’s the thing about Baldur's Gate 3 lift the shadow curse—it’s not a single checkbox. It’s a massive, multi-layered soul-searching mission that requires a specific druid, a dead man's lute, and a very creepy game of hide-and-seek.
Most players think beating Ketheric Thorm is enough. It isn’t. You can kill the big bad and still leave the region a necrotic wasteland. If you want those beautiful green trees to actually return in the ending cutscene, you have to do the legwork with Halsin.
The Art Cullagh Problem
Basically, everything starts at the Last Light Inn. You’ll find a guy named Art Cullagh lying in a bed, staring at the ceiling, mumbling about someone named Thaniel. He’s in a magical coma. You can’t just shove a potion down his throat.
To wake him up, you need a very specific item: the Battered Lute. This isn't just sitting in a chest somewhere easy. You have to head over to the House of Healing—which is easily one of the most disturbing spots in the game—and deal with Malus Thorm. He’s the undead "surgeon" with the scissor-handed nurses. You can fight him, sure. But if you’ve got a high enough Persuasion or Deception skill, you can actually convince his nurses to "practice" on him instead. It’s dark, but hey, it saves you a tough fight.
Once he’s dead, grab that lute. Head back to Art, play the tune, and he’ll finally wake up and mention Thaniel.

Why You Absolutely Need Halsin
Here is the kicker: if Halsin died in Act 1 or you never recruited him, you’re basically locked out. You cannot lift the shadow curse without the big guy.
Once Art wakes up, go talk to Halsin at your camp. He’ll get all intense and tell you to meet him by the lakeshore near the inn. This leads to the infamous "Portal Fight."
Do not go into this fight unprepared. You have to protect a portal while Halsin is inside the Shadowfell. Waves of shadows, wraiths, and undead will swarm you for several turns. I’ve seen entire runs end here because people didn't bring enough Area of Effect (AoE) damage.
- Shadowheart is your MVP. Use Spirit Guardians. It creates a "no-go" zone for the smaller shadows.
- Wall of Fire or Hunger of Hadar are lifesavers for the archers spawning on the hills.
- Don't let the portal's HP hit zero. If it breaks, Halsin is gone forever.
Finding Thaniel’s Shadow (The Oliver Quest)
Halsin comes back with a kid named Thaniel, but the kid is "hollow." He’s missing his shadow-half. That half is a bratty little spirit named Oliver who lives in a ruined house to the east (The House in Deep Shadows).

When you find Oliver, he’s going to want to play hide-and-seek. You can play along, or you can just tell him you know who he is. Eventually, he’ll get mad and run through a portal. Follow him. You’ll end up in a fight where he’s protected by a "Nightdome."
Pro-tip: Don’t attack Oliver directly while the dome is up. He has a "Vengeful Shadow" aura that reflects damage. Instead, kill the "mummy" and "daddy" shadows he summons. Every time you kill his "family," the dome loses health.
Once the dome breaks, you have to talk him down. If Halsin is in your party, he has some great unique dialogue here to convince Oliver to reunite with Thaniel. It’s actually kind of touching, in a weird, fey-magic sort of way.
The Final Step Most People Forget
You’ve reunited the boys. Thaniel is chilling at your camp. You’re done, right?
Nope.
The land still looks like a nightmare. Thaniel will tell you that the "anchor" of the curse is still Ketheric Thorm. You have to proceed with the main story, go through the Gauntlet of Shar, and eventually defeat Ketheric at the top (and bottom) of Moonrise Towers.

Only after Ketheric is dead and you are physically leaving the Act 2 map toward Baldur's Gate will the curse actually lift. You'll get a cutscene where the sun breaks through and the plants start growing back. It’s one of the most satisfying moments in the game.
Common Mistakes and Weird Bugs
Kinda weirdly, if you kill the Nightsong, it makes the curse much harder to deal with emotionally, but the quest is technically still possible as long as Art and Halsin are alive.
However, if you enter the Shadowfell (the point of no return in the Gauntlet of Shar) before you wake up Art Cullagh, the quest might fail. The game is usually pretty good about warning you, but it’s easy to get distracted by Shadowheart’s drama and forget about the sleepy guy at the inn.
Also, if Art Cullagh dies during the Marcus attack on Last Light, don't panic. You can actually use "Speak with Dead" on his corpse. He’ll still give you the info you need about Thaniel, and you can still progress the quest.
Actionable Next Steps for Your Playthrough
- Check your Journal: If "Lift the Shadow Curse" isn't there, go talk to the sleeping man in the Last Light Inn.
- Clear the House of Healing: Get that Battered Lute before you even think about entering the Gauntlet of Shar.
- Respec for the Portal: If you’re struggling to protect Halsin, go to Withers and make sure you have someone with Spirit Guardians, Fireball, or Slow.
- Keep Halsin in the Loop: Always talk to him after major milestones (waking Art, finding Oliver) to make sure the quest triggers stay active.
- Finish Ketheric: Remember that the "healing" doesn't happen in real-time. You won't see the green grass until you're literally clicking the road to Act 3.
