Sacred Tear

The Sacred Tears are items featured in Skyward Sword.

Location
The Tears are found within the Silent Realm of each respective region: the Tears of Farore for the Faron Woods, the Tears of Din for the Eldin Volcano, the Tears of Nayru for the Lanayru Desert, and just Sacred Tears for Skyloft. These tears have a similar function to that of the Tears of Light from Twilight Princess.

Uses
To leave the Silent Realm, gain spiritual growth, and obtain a new item required to locate the Sacred Flames and, later, the Triforce, Link will have to collect fifteen Sacred Tears to store into the Spirit Vessel. However, powerful Guardians will be patrolling the area and chase after the young hero. As such, Link must use the tear-shaped items in the alternate reality to stun the creatures for 90 seconds while he continues to look for the rest of the tears.
