if you got the avatars in the level20 fights the forksbecome useless i think so may as well toss em,
if you didnt get them in the level 20 fights then you can still toss em and pick up new ones for the cloister warps anytime ya want.
also fenrir is easy to get, if your on alexander i'll even help you, lol. diabolos is the *** to get,
some ppl say daiabolos is a piece of cake and fenrir is hard as nails, for me its the other way round lol,
