The Blue Crystal is the second of three Crystals found in Castlevania II: Simon's Quest.
The Blue Crystal has the ability to drain a waterlogged area in order for the player to pass through. It also has the same ability as the White Crystal, which allows to see invisible platforms. In order to obtain a Blue Crystal, the player must first have bought a White Crystal from a merchant in the town of Jova and then trade it for a Blue Crystal from a Crystal Trader in the town of Aljiba.
The only waterlogged area this item can help to get through is Yuba Lake, which is at the end of the Lower Road to the east of the Aljiba Woods. Pressing down for a few seconds will cause the water to drain and the path to Rover Mansion will be accessible.
This item can be traded up for a Red Crystal from a Crystal Trader from the town of Aldra, which has all the abilities of the White Crystal and the Blue Crystal, plus the ability to summon a transportation tornado spirit at a certain location. The Red Crystal's water drain location can also help in getting to another area later in the game.
