You will always be able to perform Magecraft regardless of location. You are a Mystery on your own, fueling your Magecraft with the wisps of your endless future potential. Your circuits are no longer static, allowing you to craft new circuits and increase their quality with no limitation, making multiple Magic Crests is not an impossibility for you. You are able to craft new magic circuits that are meant for a singular form of Magecraft, improving the initial efficacy of the specialized circuit tenfold at the cost of all non-specialized Magecraft being ineffective. Your soul will not be overloaded at any point due to too many circuits, removing the innate pain of Magecraft. Given enough time and practice, every Mystery of yours can reach the realm of True Magic.
