Quick Glacial Augment idea
Glacial augment could evolve with your champion level.
My current thoughts are :
Glacial Augment At level 6, applying the slow from glacial augment to a target already slowed for at least 50% root the target for ... seconds At level 11, applying the slow from glacial augment to a target already slowed for at least 50% stun the target for ... seconds
Just dunno how long of a CC it should apply.
may abuse it, but I think it is not that bad. It may work based on how long the duration of the Root is.
