Really there is only a couple things that bugged me and only a little. there is this thing with a comedy relief horse, the group is actively hunting spirits that can possess people and animals so if your horse starts behaving way too smartly and exhibiting focused violent tendencies, that should be a red flag of the highest degree.
and it seems for some reason jim spends a literal year in the beginning not practicing at all with his light and dark chi it seems like that should have been at the top of his to do list.
