This page explains how to find the Maag No'rah shrine.
How to Find the Shrine
To find this shrine, it helps to bring a heavy weapon with you, like an Iron Sledgehammer.
This shrine is hidden in a cliff wall west of Monya Toma Shrine. From Monya Toma Shrine, go northwest to the Maritta Exchange Ruins on Salari Plain (west of Serenne Stable). There is a tall platform southwest of the ruins. If you climb it, you can see some small ledges on the face of the cliff with ore deposits on them. Climb up those ledges and you will be able to see cracked stones in the wall. Carefully land in front of the cracked stones. Use a heavy weapon to break the rocks, or use a remote bomb and climb away before detonating it. Then go inside to find Maag No'rah Shrine.
Treasure Chest in the Shrine
The chest in the shrine contains a silver rupee.
