In Remnant 2, you'll have to solve a few puzzles as you travel to different worlds. One of the many puzzles you'll encounter is the Yaesha music box, which is broken when you first encounter it. Before you can complete the Yaesha main quest, you'll need to repair this music box.
Remnant 2 Forbidden Grove Music Puzzle / Bridge Puzzle Solution Guide
Remnant 2 offers little guidance or direction when it comes to fixing this box—or any puzzle, for that matter. You have to figure out the solution yourself, which made the game very confusing for me.
Near the music box, my co-op partner and I found a small room with a journal inside. The journal contains the solution to the puzzle, with the symbols in the order they must be entered into the box to crack the code. A dash means that no node in that line should be selected.
Before you can get the music box working, however, you’ll need to navigate through other parts of the dungeon to reach a lever. Near the journal are two doors. On the other side of one door is a staircase with a lever that you need to pull so the music box will work if you enter the right nodes. The game doesn’t tell you to pull a lever, so my co-op partner and I had to find this out the hard way.
