- Maps for Heroes 3

You need to get water from an expert. This involves either freeing a guy from prison or leveling up Dess. Start the game and go up. There, near the witch's dwelling (where you gain skills), there's a skill for water that's already learned. If you don't want to use that skill slot, go even higher; there's a prison with a guy who provides the water skill.
By the way, where and how do you guys get the Admiral's Hat?
