Sacred Water is pure water found only at the Skyview Spring. After being attacked by Ghirahim,[5]Faron must heal in a basin of Sacred Water. When Link first encounters Faron, she is in need of another dose of Sacred Water in order to fully recover. Link must then bring a Bottle of Sacred Water to Faron,[6] restoring her powerful true form, and thus opening the way to the Ancient Cistern. When embarking on this task, new and more powerful enemies appear within the Skyview Temple, with one door been resealed by enemies, forcing Link to find the Key again. In order to access the Skyview Spring, Link must defeat a trio of Stalfos in the boss chamber.
