It took two days for Max's body to regenerate in the celestial realm after being destroyed by karmic backlash, after which Rudra came to visit him, asking if he had gotten a grasp of how to use karmic essence.
Max, although having used the force only once, felt like he had grasped the basics of its power and was truly awestruck at just how potent it was compared to normal divine essence.
Using karmic essence was like charging a car with nitros instead of gasoline as the power output of every aspect of one's body increased significantly when used.
However, just like nitros, using karmic essence came with a cost to the engine as it damaged one's body and caused it to fall apart from the intense strain of bearing the output load.
