En Passant

ARAM:Mayhem stats for the En Passant augment — best champions, class performance and co-picked augment synergies.

You can now identify the Vitals of enemy champions within 2000 units, marked as an arc around them and pointing towards a specific direction. Vitals on targets become exposed instantly once you are within range and remain exposed until you die. 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 infinitely. Each En Passant stack increases the consumed Vital damage and bonus movement speed. 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.
