Ease Cave is a dungeon within the original Breath of Fire.
Ease Cave is a cave located southwest of Romero and northwest of Camlon. It is located on an island in a lake surrounded by forests and mountains. It houses the spring of Cleansing Water as well as the Agni.
Having agreed to rid Romero of zombies, Ryu and his party head to Ease Cave where it is rumored that the Cleansing Water can be found. Ryu's group journey through the cave and by using the WatrJr obtain the Cleansing Water they need to save Romero.
After Ryu has gained all of the other dragon abilities the party can return to the spring in Ease Cave and by using the Gills go into it. Once there Ryu can learn the Agni dragon ability.
