A complex maze of interconnected corridors, a Runebarrow, holds many hidden devices waiting to be discovered. Here are all the Proving Grounds floor mechanism locations in Eiyuden Chronicle Hundred Heroes.

The floor mechanics for Proving Grounds in Eiyuden Chronicle: Hundred Heroes lie beyond the runestone riddles. After you solve them (and we can show you how to solve the three runestone riddle), don’t go to the helicopter landing site, just go the other way, and you’ll find them.

When you first arrive at the Proving Grounds, you’ll see the control panel and a strange looking room. Activating the control panel will cause the room to rotate, creating new paths. You can see which paths are open by following the blue lines on the floor.

At this stage, you can only rotate the first third of the room. If you turn the panel to red, the path to the left will open, and if you follow it, you will reach the helipad that leads to the lower room. If you follow the blue line, you will come to three runestones and three lanes. If you press the switches in the correct order (left-right-middle), all the stones will align in one lane, allowing you to clear the middle lane and walk through it.
