(But on a serious note, I've read datamined descriptions of the love scene...and hoooo boy, Larian is treating Astarionmancers to a full course steak dinner from the looks of it :3)
I pray it's the latter because, in my case, being an Astarionmancer and not being evil means desperately picking up any approval breadcrumbs that don't involve manslaughter or rejecting assistance quests.
tl;dr would any astarionmancers be willing to lay out the pros and cons of giving him the book if i also really want my character to have it, without going into too many specifics?
