Portal Keys are keys that unlock stages temporarily. You can get these keys from Heimdall, the Portal Key Maker located in the "Portal Keys" house in the Main area. These Portal Keys are used to open specific stages in the Portal. These stages require keys, because they give materials which are high in demand.
