Gangplank Ability (LoL): Powder Keg

Gangplank places a powder keg that can be attacked by Gangplank and enemy champions for 25 seconds. When an enemy destroys it, the keg is defused. When Gangplank destroys it, it explodes, slowing by 30 / 37.5 / 45 / 52.5 / 60% (+0.25% per 1% crit chance) for 2 seconds and dealing the attack's damage, ignoring 40% armor. Champions take an additional 75 / 105 / 135 / 165 / 195 physical damage.

Keg health decays every 2 / 1 / 0.5 seconds. Keg explosions detonate other kegs with overlapping blast zones, but don't deal damage to the same target more than once. Keg explosions triggered by Parrrley will grant the bonus gold for targets killed.
