Rumble Ability (LoL): Electro-Harpoon

Rumble launches an electrified harpoon, dealing 55 / 80 / 105 / 130 / 155 (+50% of ability power) magic damage, slowing by 15 / 20 / 25 / 30 / 35% for 2 seconds, and reducing the enemy's magic resist by 10 / 12 / 14 / 16 / 18% for 4 seconds.

Hitting an enemy who's already slowed by this ability increases the slow to 22.5 / 30 / 37.5 / 45 / 52.5% and reduces the enemy's magic resist by 18 / 21 / 24 / 27 / 30%. This ability has 2 charges (6 second refresh).

Danger Zone: The harpoon deals 90 / 127.5 / 165 / 202.5 / 240 (+75% of ability power) magic damage instead and the slow and reduced magic resist are increased by 50%.
