"I'm also curious to know if it's now possible to knock her out when defending the grove? I also want to know if it's still possible to romance her on the good path? I ask because I'm not an expert on Minthara, it's my first time recruiting her.
Yeah you can romance her, you just don't get a sex scene out of it and miss the dialogue when rescuing her about hoping you'd show up (which apparently are the ONLY things still functioning properly on the evil path unless Crimson comes back to say otherwise if there are unlisted Patch 6 changes).
Does she have a romance scene in act 3 now, or is it still bugged? Super curious to know.
Do you mean the way she tells you she's yours tonight and nothing happens? Cuz there was never a bug for that, just early on a lot of people (myself included) thought it was bugged, but there's no sign of a scene for that in the files at all last I checked. That's big enough I can't imagine it wouldn't get a patch note if they added one.
