If the missile hits an enemy champion, the sharks circle around their location in a 425 radius instead for 3 seconds, dealing「 25 – 75 (based on level) (+ 20% bonus AD) (+ 12% AP) magic damage every second 」「 75 – 225 (based on level) (+ 60% bonus AD) (+ 36% AP) total magic damage over the duration 」to enemies within the area and slowing them by 30% for 3 seconds. If Mark is not equipped, you will be prompted to replace one of your summoner spells with Mark.
