Probably a design oversight since GR was introduced before Korg and the devs didn't check all champs for actual projectile attacks. But you shouldn't use special while he has rock shield up, only light attacks to avoid the thorn damage.
It makes contact, therefore is not a projectile attack
It makes contact, therefore is not a projectile attack That doesn’t make any sense. Imagine I punch a knife. It’s going to hurt; my hand is going to be cut. Now imagine that in my anger at the knife I buy a flamethrower and use it on said knife. The knife will not cut the flame, nor will it cut my hand via the flame. That doesn’t make any sense. Even if the knife did somehow inflict a wound on the flame (let’s ignore how ridiculous that statement is), I still would not feel any pain, as the flame is not part of my body, and is not connected to my nervous system. There’s no reason that shooting flames at a knife should inflict pain on your body — unless you burn yourself.Warden out ~
