Misko's Treasure of Awakening I
Tears of the Kingdom
"On the Tabantha Frontier, where Rayne, Piper, and Tanagar meet, ruined pillars stand together. One of those mighty pillars opens the way to my treasure."
This Side Quest starts in Goronbi River Cave. Go to the Ancient Columns in the Rayne Highlands, open the Ancient Columns Cave, and open the Treasure Chest to receive the Tunic of Awakening. Reading the nearby pedestal starts Misko's Treasure of Awakening II.
