SO! Fai is actually a real DnD Character! She was very easy to do because I already use her for Curse of Strahd, so these are her current Curse of Strahd stats. I'll give ya so of the art from CoS.
This last picture is her CURRENTLY! She just became a Daywalker with the help of an angel. Not going to spoil anything with CoS other than that.
Make sure you look at all the intermissions before this starting from Intermission 50
