U seem to be confused. Oath of Judah is NOT a level 50 Pri Arm. It is a level 50 divine key. If there was a Pri arm for Judah, you could still use it. There is no Pri arm for Judah. So you can’t use another divine key, for another divine key Pri arm.
You called Oath Of Judah a Pri arm lol. Judah is not a Pri Arm, and will probably never be a Pri arm. You CAN use divine keys, for Pri Arms. But ONLY if that divine key has its own Pri Arm.
