I have the Long sword but i ate the moldy bread just to see what it does, and dont eat it if you dont have about 270 hp to spare! (Oh, and i think you need the "amanita" too in order to get the posion sword in that quest not sure though,because i did that a while ago)
Also on the subject of Castlevania anyone know where the other two cards are beside the club, diamond, and joker?
(P.S. I have an idea, why don't we make a "Castlevania Shop/Co-Op Battle" thread, depending on how many people have the game it just might work.)
