You’ve seen her. She’s tall, glowing with literal hellfire, and has a personality that makes you want to follow her into Avernus. But here’s the thing: romancing Karlach in Baldur's Gate 3 is surprisingly easy to mess up. I’ve seen countless players get to Act 3 only to realize they’ve been friend-zoned by the big red tiefling because of one missing conversation in the Shadow-Cursed Lands.
Basically, if you don't play your cards right early on, she'll just call you "soldier" forever. Not the vibe you're going for.
Why You Need to Find Her Fast
Most people stumble upon Karlach after they've already done the heavy lifting in Act 1. Big mistake. You want to recruit her early—specifically before you resolve the "Save the Refugees" questline.
Head to the Risen Road, find her by the river, and listen to her side of the story. She isn't a monster; she's a victim of Zariel’s schemes. If you have Wyll in your party, things get tense. You must side with her. Don't let Wyll kill her. If you do, well, the romance is over before it started. Obviously.
Once she's in the party, you need to be a hero. Karlach loves it when you stand up to bullies and help the weak. She hates it when you're a manipulative jerk. Honestly, just don't be a "murder hobo" and you're halfway there.
The Infernal Iron Problem
You can't just kiss her. If you try, you'll literally catch fire. Her heart is an Infernal Engine, and it's running way too hot. This is where Dammon comes in. He’s the tiefling blacksmith in the Emerald Grove.
You need to find Infernal Iron. There’s a piece in the Blighted Village (check the basement of the house with the spider webs) and another in the goblin camp (Dror Ragzlin’s treasure room). Bring a piece to Dammon. He’ll give her a temporary fix.
The First Move
After that first upgrade, you need to show interest. Don't be shy. Tell her you want to touch her. She’ll say she’s still too hot, but she’ll be flattered.
Here is the "pro tip" that many miss: you can actually get a "test kiss" in Act 1. You have to cool her down. Throw a bottle of water at her or hit her with a Ray of Frost. It’s goofy, but it works. You’ll get a tiny, sizzling moment that locks in the romance path.
The Make-or-Break Moment in Act 2
If you reach Act 2 and haven't flirted yet, you’re probably cooked. But even if you have, Act 2 is where the real "romance killer" bugs live.

First off, Dammon must be alive. If the Last Light Inn falls or if you let the Strange Ox die in a way that messes with Dammon’s spawn, your romance is dead. No mechanic, no heart fix, no touching.
When you find Dammon at the Last Light Inn, give him the second piece of Infernal Iron. This is the big one. After he fixes her, she’ll finally be able to touch people without incinerating them.
Wait for the exclamation mark. Don’t just run off into the Shadow-Cursed Lands. Go to camp. Long rest. You might have to rest a few times to clear out other "camp events" like Wyll’s dancing or Mizora’s nonsense. Eventually, Karlach will approach you at night. This is the scene where the romance truly cements. If you choose the "hug" option instead of the "kiss" option, some players report getting locked out of the spicy scenes later, so keep it romantic.

Common Pitfalls (And How to Avoid Them)
- The "Three's a Crowd" Rule: Baldur's Gate 3 is a bit jealous. If you’re already romancing Shadowheart and Lae'zel, Karlach might not even give you the time of day. You usually need to break things off with others by the time you reach the middle of Act 2.
- The Goblin Camp Choice: If you side with Minthara and raid the Grove, Karlach leaves. Period. No romance, no companion. She has a moral compass, and "slaughtering refugees" is firmly in the 'No' column.
- The Dammon Bug: Sometimes Dammon just... disappears or dies if you don't talk to him immediately at the Last Light Inn. Make him your first stop after meeting Jaheira.
Actionable Steps for a Successful Romance
- Recruit her immediately at the Risen Road and defend her against Wyll.
- Loot Infernal Iron from the Blighted Village or Shattered Sanctum before finishing Act 1.
- Talk to Dammon in the Grove for the first upgrade and choose the flirty dialogue.
- Cool her down with water/ice for the first kiss scene in camp.
- Ensure the Tieflings survive Act 1 so Dammon appears in Act 2.
- Get the second upgrade at the Last Light Inn and trigger the long rest scene before completing the Gauntlet of Shar.
If you follow these steps, you’ll have the best barbarian in Faerûn by your side. She’s one of the most rewarding romances in the game, mostly because her story is so raw and emotional. Just keep some water bottles handy for those early days.
