'That doesn't need to be the case,' Jack thought.
Master might have exhibited an ability similar to form manipulation, but he hadn't heard about Master exhibiting a similar ability outside of that one time. He remembered when he was under the effect of Lightning God Incarnation, everything felt slightly different. It was not as profound as when he was under Mana Awakening, but close. Probably this special condition let one exhibit an ability one couldn't have pulled off under a normal situation.
He thought about when he altered the finishing blow of Lightning God Incarnation. He didn't alter its form as Master did. What he did was simply suppress the accumulated energy from being released and focused those constrained energy into his fist to deliver one powerful punch. It was not fully a form manipulation but was still an alteration. Perhaps at that time, he had already touched the realm of form manipulation without realizing it.
