Unique - Between the Ribs:

You can now identify the Weakpoints of nearby enemy champions, marked as an arc around them and pointing towards a specific direction. Weakpoints on targets take 4 seconds to become exposed and linger for 11.25 seconds afterwards. Dealing damage while you are facing an exposed Weakpoint will consume it to deal bonus true damage equal to 3% (+ 3% per 100 AD) (+ 2% per 100 AP) of the target's maximum health and grant you 50% – 75% (based on level) bonus movement speed for 1.5 seconds. Once a target's Weakpoint is consumed or expires, you identify a new Weakpoint on them.
