シャークテンペスト

Your Mark is empowered to circle sharks around it in a 300 radius, dealing 100 – 200 (based on level) magic damage to enemies it passes through as it travels and slowing targets hit by 40% for 1 second. If the missile hits an enemy champion, the sharks circle around their location in a 425 radius instead for 3 seconds, dealing「 30 – 90 (based on level) (+ 25% bonus AD) (+ 15% AP) magic damage every second 」「 90 – 270 (based on level) (+ 75% bonus AD) (+ 45% AP) total magic damage over the duration 」to enemies within the area and slowing them by 40% for 3 seconds. If Mark is not equipped, you will be prompted to replace one of your summoner spells with Mark. The damage dealt by this augment counts as area damage, thus it is able to trigger spell effects.
