I started another game to try a monk character out with the intent of romancing Viconia but I'm wondering if I should've made him LN instead of LG for the romance to take place. Anyone know?
Yep, she doesnt really care about alignment, only thing that matters is your race.She wont romance Elves or HalfOrcs (although she should, some error with halforc race definition) to my experience.
LG human monk is ok.
