Porcupine ARAM Augment

You build up a burst of needles from within you when taking damage from enemy champions, storing up to 400 – 3900 (based on level) pre-mitigation damage taken. After reaching the maximum damage stored, you consume the stored damage to burst the needles outward in a 400 radius, dealing 75 – 200 (based on level) (+ 125% bonus armor) (+ 125% bonus magic resistance) physical damage to enemies hit and slowing them by 30% for 2 seconds.
