There are a total of six Music Box Scored scattered across the region and one of them is the Dies Irae Score. If you have been looking for a guide explaining its exact location, you have come to the right place.
Where To Get Dies Irae Score In Genshin Impact
You will find Dies Irae Score by going to the Caesareum Palace in the Sea of Bygone Eras. You can reach there by going to the Initium Iani teleport waypoint and then taking the route marked on the map above and going straight.
