Karlach/Romance

Karlach can be romanced.

Companion

Her first scene can be during Chapter One. If the player has Medium approval you can drum up the courage to tell her how much you like her. This will lead to Karlach meeting you, once you have gone to bed and everybody else is asleep. Alternatively, if the player has High approval, Karlach will do this on her own. Since you haven't been able to continue with The Hellion's Heart past the first step in Chapter One, you will not be able to touch her. You can convince her, however, to kiss you - which you can either end sooner or embrace the moment, only to burn your lips.
After reciprocating her feelings, one can tell her how much they would love to touch her. As well as figuring a way to cool her down with water or frost magic for a quick embrace, going into a discussion of letting them have fun with others while she's unavailable due to the engine.
Once you reach Chapter Two and arrive at the Last Light Inn, you can repair Karlach's Engine with the help of Dammon. During the next long rest (and if no other events are queued), the player can sleep with her.
During Chapter Three, Karlach will ask to have a "first date" at her favorite restaurant in Baldur's Gate, where she pretends to only just be meeting you. Afterwards is a sex scene if nudity is enabled, and a kissing scene if nudity is disabled.
A new romance may be started with Halsin in Act Three with an option to check with Karlach first. When approached, Karlach will say that she is not ready. Although, she agrees to let player to have both if pushed.
It is possible to have an intercourse with Mizora. The player will be caught by Karlach at the end of it and asked to explain. She will be deeply hurt, but will not end the relationship.

Origin

While playing as the Karlach Origin, Karlach's personal story has a number of different effects on which specific romantic interactions are available to the player at different parts of the game. A list of known effects on other romance storylines is contained below, but may be incomplete.

Act One

Origin Karlach can reject Lae'zel and Astarion's advances for sex with unique dialogue options, citing that she's too hot to touch, but she can trigger the sex scenes.

Astarion's scene has unique dialogue when playing as Karlach; he will become frustrated and confused that he can't touch you, and you can suggest to just lay near each other instead, which is a novel concept for him. Karlach still appears naked in the morning.

Lae'zel's sex scene proceeds as normal, as if Karlach were not literally too hot to touch.

Origin Karlach is not prevented from romancing Wyll, and pursuing this option does have a handful of unique lines acknowledging Wyll's prior objective of hunting Karlach down.

Dammon's interactions with an Origin Karlach character seem to be generally more flirtatious than when talking to other characters.

Act Two

After delivering a second piece of Infernal Iron to Dammon at the Last Light Inn, Origin Karlach is given additional unique options for how to respond. In addition to simply saying "Thank you", these are:

Pause. Is he flirting with you?
Take your leave - you have someone you really want to touch.

Neither one of these options appear have immediate consequences, but after wrapping up conversations from this scene, Origin Karlach is able to fully engage in usual romantic interactions with other characters.
