The developers of Baldur’s Gate 3 designed most questlines so that they may be completed in multiple ways. Thus, giving the players more freedom in how they approach situations. This guide represents one method that is confirmed to unlock this achievement or trophy.
The Hot Date achievement/trophy is difficult to pull off, and it is easy to get stuck in a state where you can’t fix the situation. This is a sequence of events that are confirmed to work, and it may contain extra steps.
A full achievement guide is available here:
https://tigorestips.com/dnd/baldurs-gate-3-achievements-trop...Act 1
Start in the Blighted Village and head northwest out of the village past the windmill (event there). Just after the windmill jump over a crack in the wall to the north and continue along the path until you jump over a broken bridge. Then, head east working your way down toward the river. Eventually, you will find Karlach on the south side of the river just across a log bridge where you can invite her to meet you at camp.
Try to find Karlach as soon as you can and keep her in your party at all times. You need her there to help boost her relationship with you by doing things she approves of. As soon as you find her, add Karlach to your party and head up the hill to deal with the paladins. After they are defeated, ask her “That fight at the tollhouse really…heated you up, didn’t it?” Followed by “I liked the look of it.” That will get you started down the long path of flirting with Karlach and will introduce you to her heart condition. Let her know that there are tieflings in the druid grove nearby.
It may be optional, but also finding her early in Act 1, gives you the chance to meet Dammon with her at the Emerald Grove.
After saving the tieflings, they will join a party at your camp. During the party, talk with Karlach again and say “I think I’ve drummed up the courage to tell you how much I like you.” When you initiate the long rest, she will visit you by the fire. The dialog options are up to you, but keep them positive and don’t reject her. The next morning, talk to Karlach again and say “I’d like to try cooling you down somehow…” Switch to Gale and cast Ray of Frost or another ice/water spell on Karlach.
Infernal Iron
You will need 2 pieces of Infernal Iron for the events that take place in Act 2. There are many places to find the material throughout the game. Here are a few easy early spots.
The first piece of Infernal Iron can be found in the blacksmith’s room under Blighted Village in the Whispering Depths. When you’re in the room with the blacksmith’s forge, climb the ladder in the northeast corner and collect the iron from the chest.
A second piece of Infernal Iron is located behind Dror Ragzlin in the Shattered Sanctum. On the balcony above Dror is a locked gate with a pile of treasure. Among the treasures, you will find a piece of Infernal Iron.
Another piece of Infernal Iron is located in the Masons Guild building just north of the Tollhouse in Act 2. This piece is found sitting on a table next to a pile of stone slabs.
Act 2
When you reach the Last Light Inn during Act 2, make sure you have Karlach in your party and talk to Dammon, the blacksmith. He will offer to fix and upgrade her Infernal Engine if you supply him with Infernal Iron (you need 2 pieces). The order of the next set of events is critical. If you deviate too far, you may lock out the option for the date in Act 3.
After the 1st upgrade, say:
- “I still can’t touch you, though…”
- “Of course I do.”
Head to camp for a long rest, but don’t take it yet.
Say:
- “Karlach, I’d love to be able to touch you properly.”
- “I’d take your hand in mine.”
Finish the long rest.
Have Dammon upgrade the Infernal Engine a second time.
Say:
- “I’m so happy for you. For both of us, if I’m honest.”
- “I can’t wait for tonight. I’m going to hold you as close as possible.”
Head to camp for another long rest, but don’t take it yet.
Say: “Of course. Nothing would make me happier.”
Start the long rest.
Say:
- “Hello, darling.”
- Choose which ever options you want to not completely reject her.
In the morning, say:
- “I loved being able to touch you last night.”
- Choose either of the first 2 options.
- Choose deception. She prefers if you lie about her situation.
- Choose any option after that to not reject her.
Act 3
At this point, you will need to progress the story into Act 3. When you reach the start of the act, you can take a long rest and ask Karlach: “It’s been a while since we connected like we once did.” This will prompt her to mention her plans for the future.
When you finally reach the Lower City, head to camp for a long rest. Karlach should have a quest marker over her head and the date sequence will begin. Choose the dialog options you think work best as long as you don’t reject her. The Hot Date achievement or trophy will unlock after the end of the interaction when you return to camp.
