Unlike other mele fighters, Rishi had sufficient ability to deal Ranged damage, so he didn't need to make his Zone similar to that of mages. He could decide to take a balanced approach, but before that, he needed to figure out his Spirit Energy.
He closed his eyes and sat in a meditative state. It took him some time, but before long he was able to bring out his Spirit Energy. An average person is able to create a circular area with a three-meter radius with his Spirit energy. He can then compress his Energy to create a smaller area or extend it to create a larger area.
