Master cast two spells simultaneously using his two magic staffs. Both were cast extremely swiftly.
One of the spells was Telekinesis. The blob which was about to strike Master using its arms suddenly found itself unable to move. Master's intelligence stat was so high that his Telekinesis was able to contest the strength of this large monster.
With his telekinesis holding down the blob, he could peacefully complete his other spell which took a slightly longer time. The spell was Gravity Field. A black ball appeared next to the blob. This black ball released massive gravity that made the blob unable to move.
Master then cast another spell, Teleportation. He disappeared and reappeared up on the roof.
At the same time, Jack was already up there. The limiter-off stone lasted only one short minute, so he had to make every second count.
