She’s a ten-foot-tall tiefling with an engine for a heart and a smile that could power the Lower City. Karlach is, for many, the undisputed MVP of Baldur's Gate 3. But romancing her? That’s where things get messy. Not "bad" messy—more like "accidentally-ending-your-relationship-because-you-talked-to-the-wrong-wizard" messy.
The Baldur's Gate 3 Karlach romance isn't just about high approval. It’s a literal race against time and internal combustion. If you’re looking for a simple "press X to love" guide, you’re in for a rough ride. This is about managing a ticking time bomb while trying to find a blacksmith who doesn't mind working with soul-infused metal in a barn.

Honestly, she’s the most "human" character in a game full of vampires and space frogs.
Why You Keep Failing the First Act
Most people screw this up before they even leave the Emerald Grove. You find her by the river, she’s covered in blood, and she’s perfect. But the romance doesn't start with a conversation. It starts with Dammon.
If Dammon dies, the romance dies. Period.
You need Infernal Iron. You can find the first piece in the Blighted Village basement, tucked away in a chest that’s basically screaming "trap." Take that iron to Dammon at the Grove. He’ll give her the first upgrade.
Here’s the kicker: even after the upgrade, you can’t touch her. If you try to kiss her, you get burned. You can literally throw a carafe of water at her face or use Create Water to cool her down for a single, sizzling second of physical contact. It’s tragic. It’s also the only way to lock in the "Early Access" phase of the relationship.
The Party Problem
The Tiefling Party after saving the Grove is the ultimate "make or break" moment. If you haven't expressed interest by then, or if you spend the night with someone else (looking at you, Gale), Karlach might just stay your "best mate" forever.
You’ve got to tell her you like her. You’ve got to mean it.
Act 2: The Dammon Survival Horror
By the time you hit the Shadow-Cursed Lands, the stakes get stupidly high. Dammon is at the Last Light Inn. If the "Strange Ox" (that weird cow from the Grove) loses its mind and kills him, or if Marcus kidnaps Isobel and the whole inn turns into shadows, say goodbye to your romance.
You need a second piece of Infernal Iron.
Once Dammon does the second upgrade, the "Heat" mechanic finally chills out. This is where the first real intimacy happens. But wait. If you’ve been flirting with Wyll or danced with the wizard, Karlach will ask you to choose. She’s poly-friendly in theory early on, but eventually, the game forces a "Lock-In."
Don’t be a dog. Pick the big red lady.
The "Good" Ending Debate
Is there a happy ending? Sorta.
Karlach's engine is fundamentally broken. Dammon tells you flat out: she either returns to Avernus or she dies. For a long time, fans were convinced there was a secret "fix" involving the Steel Watchers in Act 3.
There isn't. Larian has been pretty firm on this through multiple patches.
Your choices at the end are basically:
- The Dock Scene: She burns to ash on the pier. It’s one of the most soul-crushing scenes in modern gaming.
- The Avernus Run: You go to hell with her. If Wyll is the "Blade of Avernus," he can go too. You basically become a demon-slaying power trio.
- The Squid Option: She becomes a Mind Flayer. Her engine stops, she lives, but... is she still Karlach? Most fans say no.
How to Actually Get the Date in Act 3
In the Lower City, Karlach will eventually ask for a real date at a restaurant called The Singing Lute. It’s awkward. It’s adorable. You’ll have to deal with a server named Henk who is terrible at his job.
To trigger this, you need high approval. How do you get it?
- Kill Gortash. This isn't optional for her mental health.
- Be Kind. She hates bullies and loves kids.
- Don't be a "Dark Urge" Psycho. If you start killing innocents, she’s out.
Actionable Tips for the Road
- Hoard Infernal Iron: You only need two for her heart, but extra iron lets Dammon craft the Flawed Helldusk armor set.
- Save Often: Especially before entering the Last Light Inn. The AI for Dammon is... not great at staying alive during combat.
- Talk to her after every Long Rest: Her dialogue triggers are often buried under other camp events.
The Baldur's Gate 3 Karlach romance is a masterclass in bittersweet writing. It’s not about finding a magical cure; it’s about making the most of the time you have left. Whether that’s a dinner date in a city under siege or a literal leap into the fires of Avernus, it's easily the most rewarding path in the game. Just bring a bucket of water for Act 1. You'll need it.
