Should I work with it?

you seem to have no idea what going to be doing with it. you're mostly using it to farm quests for money. my suggestion would be to not play it because you dont seem interested in playing. as a magician, you should notice that no matter how much your equiping this priest so far, his damage is not going up by a lot. so you can go out and train, play, etc to see if you actually like it because you arent suffering too much from lack of equipment.

you really dont know what a bishop is like until you get genesis so until then i would hold off on putting serious effort into funding it.
