Zed's TRUE Power
One thing to remember is that in game limitations for the sake of balance, do not necessarily exist within lore. In Zed's teaser image posted by Champion Herald NeeksNaman we see Zed with....9 shadows.
What is the upper limit of shadows that he can create? What is the limit of how often he can swap with them? And in lore, it appears they may be mobile, and able to attack in melee -is this true?
