How to Use Tatarasuna Keys

Use to Open the Arsenal Gate

After collecting all three Keys to Some Place, head to the Arsenal gate at the bottom of the Forge area. Aim for a spot directly below the U in Tatarasuna on the map.

It's easy to spot from above, as the grass in front of it is a lighter color and it's sandwiched between an Electrogranum and a Lightning-Struck Tree. We highly recommend picking up the Electrogranum before heading inside!
