Alright, we all know sometimes moon phases affect things subtlely in vanadiel (alegedly) but why should abyssea be any different? Im sure we have all seen, and heard of somthing dropping insanely frequently, then not at all during an attempt, i have a feeling lunar forces are at work here, i have no evidance of this, it could be dumb luck/unluckyness, but it never hurts to do a bit of research, so i guess keep your eyes open in abyssea, if there is some pattern, and we learn it, it may mean more desired drops for everyone!
