You can now identify the Vitals of enemy champions within 2000 units, marked as an arc around them and pointing towards a specific direction. Dealing damage to a target with a basic attack or ability while you are facing in the direction of their exposed Vital will consume it, dealing bonus true damage equal to 6% (+ 1.5% per En Passant stack) of the target's maximum health, healing you for 50 – 200 (based on level) (+ 5% missing health), and granting you 50% (+ 5% per En Passant stack) bonus movement speed that decays over 2 seconds. Consuming a target's Vital also grants you an En Passant stack for 8 seconds, refreshing on subsequent Vital triggers and stacking up a number of times. Each En Passant stack increases the consumed Vital damage and bonus movement speed. Vitals on targets become exposed instantly once you are within range and remain exposed until you die. Once a target's Vital is consumed, you identify a new Vital on them pointing in a different direction from the previous after 4 seconds.
