Knockback immunity.

I've tried on the gameplay forum to find if there is anyway to get this other than kaoms roots, doesn't seem to be any.

You can pretty much get immunity to anything in the game through one way or another or atleast mitigate it. If there is not something that i'm missing, suggesting for it to be added on somewhere more accessible to kaoms. Some suggestions, jewel implicits, clusters, mastery, pantheon and or unstopable for jug so is not being stopped.
