Shadowheart/Romance

Shadowheart can be romanced.

Act 1

In Act One, her first important romance scene will be unlocked when you are in the camp by her proposing to have a drink in private with you. Shadowheart will only propose it to you if you have at least medium approval. You'll meet her away from camp later that night, where you will have a deep conversation. After some dialogue, the camera fades and returns a few hours later showing both of you laying on the ground, holding hands. You can choose to kiss her, and then both will return to camp.

Alternatively, if her approval is raised quickly enough, a new dialog choice will appear; "I can't help but feel like you and I might have missed a chance to connect. Truly connect." Selecting this will allow the above scene to happen earlier, on the first night where there are no other cutscenes once the Long Rest begins.

Next day, you can have a conversation with her regarding the previous night. Her dialogue will depend on her level of approval.

In the Grymforge, you can find an Idol of Shar to give her.

Act 2

In the Shadow-Cursed Lands, you can find a Night Orchid to give to Shadowheart.

The Gauntlet of Shar is an important divergence in Shadowheart's romance.

Act 3: Sharran

If Shadowheart kills the Nightsong, she becomes imbued with Shar's power and becomes noticeably colder and distant. She will inform you that Shar is her priority, but says that her body is still at your disposal.

Later, she will invite you to a Selunite shrine. She reveals that she saved the blood that splattered on her clothing, body and hair from killing the Nightsong, and uses it to desecrate the shrine, relishing in the act.

Act 3: Non-Sharran

If Shadowheart spares the Nightsong, afterwards she admits that her relationship with you has been something she's been consciously ignoring in favor of her faith. She asks if you want to make that relationship something more serious.

Some time after, she invites you to go swimming with her. After dialogue, the camera pans away as you and Shadowheart have an intimate time.

Shadowheart will also ask you to come with her to a Selunite statue. If she chose to kill her parents, she grieves their loss and talks about the future she hopes to have after getting rid of the Absolute. If she rescued them, she sobs that she doesn't deserve to be anyone's daughter for the actions she committed in Shar's name, only for her parents to reassure her that they love her and are proud of her.
