Mystery Seal

Mystery Seal (謎封印 ; Nazo fuuin) is a keyword introduced in SD47. Currently, only Medjeowl possesses this keyword. The effect is worded as follows:
* Mystery Seal - (When Summoned) You can exchange one of your Life cores for Soul Core on your Reserve.
Mystery Seal is an alternative method to send Soul Core to Life. In exchange of directly adding a Life, the Spirit possessing it has a relatively low cost, which allows sealing in early game. While having no gain in actual number of Life, this also means the number of cores the player can use won't decrease on spot, and the effect would be unaffected by effects that stop Life increase, like Oracle XVII Over Star's Mirage effect.
