if you look in Vloume 12 it was asid that it was used to house his soul when his body was destroyed by the curse and after he got a new body all the limitations were no long their like a time limit which was up to three hours a day before his body was destroy. SO he can keep it on for a full day and night and his stamina is only taken with the cardinal queen Balance Bracker form and the mini white and red dragons abilities which wears out his stamina.
