Unstoppable
Full name:Unstoppable
What it means
Status that makes a champion immune to all crowd control (stuns, slows, knockups, fears, roots, silences) for a short time. Notable sources: Olaf's R, Sion's R, Garen's R during the wind-up, and Teleport during the channel. CC bounces off you.
Example
Olaf presses R the moment a tank tries to stun him — it just gets nullified.
