"Spray foe with painful, binding mists." - Spout's short description in Dark Dawn.
When set, Spout will increase base HP by 9, base Defense by 2, base Agility by 2, and base Luck by 1.
Spout is found in the part of Belinsk Ruins that can be accessed before the dungeon is actually explored. Whenever you can freely explore Belinsk, go to the Sanctum at the center-east area of town and go downstairs into the library. When you reach the library, there are three bookshelves to the left. Move the rightmost shelf to the right, along with the center one. A secret entrance should be revealed. Go through that entrance and hop on the higher parts of the room to eventually find Spout. Spout can be found from the time you reach Belinsk to when you fight the monsters on Briggs' ship. After fighting the monsters, Spout is permanently missed.
