The Water card turns nearby dungeon floor into open water. The floor at the player's feet will remain unchanged.
- Power level 0: Each floor square within four squares of the player has a 50% chance of becoming shallow water.
- Power level 1: Each floor square within six squares of the player has a 25% chance to be turned into shallow water and 25% chance to be turned into deep water. The same six-square-radius area will then be "deepened" twice, increasing the proportion of the area that is water, and the proportion of the water that is deep.
- Power level 2: All visible floor is turned into water, destroying traps in the process. Each floor square converted that is not the player's current square has a 50% chance of being deep water.
