Of course, this happened when the Green Vine Sphere was given Totem Light characteristics.
However, these exercises had to be created, and although they were minor exercises in the Secret Technique world and therefore were very rough, once they were integrated with Totem Light, they could then be considered as rare and powerful resolutions.
However, exercises were merely exercises, and of all the people who had practiced Secret Techniques like the Southern Holy Fist Gate, Neptune Fist, Red Sand Sword, Star Ring Door and many others, how many of them had actually reached the absolute cutting edge like Garen or Cayduran?
Appraisal, perseverance,will, luck. They were all elements that one could not lack on the path to the top.
Thus, though these exercises were created, a worthy disciple would still be needed to inherit them.
