However that weapon that's so worhtless is going to help you out tons if you go up against the bosses in the Bevell dungeon. I believe it's cat nip and has the ability SOS ????. That SOS is whenever you are yellow you'll do 9999 damage, I prefer using fire gems to get lots of damage in one turn in.
