Dragon Quest IV Chapters of the Chosen. How do you gain entrance into the Water Fall Cave?

Answer 1

You need to go onto the island on the far west of the map, and there is a village of pirates, if you go there at night and look at the sea there is like a whirl pool, remember where the whirl pool was, and go there again at daytime, and stand in the spot and press a (or examine) you pick up this stone called karastaway stone or something like that, then go back to the waterfall and go up to the edge of where there are steps i think, and then go into inventory and click use on the karastaway stone, the water should clear up a bit and reveal stairs, go down the stairs, and somewhere in the cave there is the super powerful liquid metal sword!! Good luck!!
