People need to keep in mind they're still getting 5 MAB total with BOTH earrings, making Moldy + Novio/Crapaud give higher MAB. But that 5 M.Acc is pretty darn attractive, too.
Who the hell would wear crapuad earring, it isn't anywhere near worth the price tag nor worth the trouble to get, these are best option for high resistant mobs, that novio won't help your spells land more accurately, any smart blm knows this, it's good to have both if you want your spells to land constitatly. Novio+moldy is better overall, but for anything high level, or any HNM really, these would give better results, well worth the trouble.
I guess this and cassandra's earring are a set, same stats on both except cassandra has mp+5 instead of hp+5. Awesome, i hope these are not too bad to acquire.
