Floodgate Key

Floodgate Key is an item found at the end of Castle A: Skeleton Cave in Castlevania Harmony of Dissonance. It is required to drain all of the water at the lower levels of Castle A: Luminous Cavern in order for juste to proceed and fight Death. In order to use the key, Juste will have to go to the very end of the caves where the merchant's shop is near it (it is about 2 rooms to the left). The room will have a fountain and a mechanism with a cross on it and a keyhole at the bottom. After it has been used (it will automaticlly be used when you com in to the room) it will say "immense water drained away somewhere".
