Whoever designed the facility in Signalis really likes keycards. Nowhere is this more evident than in the hospital area of the game. The surgery room is locked with not one, not two, but five keycards. Each one is marked after one of five classic elements. Searching around the hospital floors will net you fire, water, air, and gold keys, but earth is nowhere to be found. Try as you might, you will never obtain the earth key, as it is inaccessible. However, what you will find is a blank key. It’s not going to work in its empty state, but if you follow a process, you can make a mock earth key that works just as well as the real one.
