Jayce Ability (LoL): Lightning Field / Hyper Charge
Lightning Field / Hyper Charge Jayce
W
Mercury Hammer Active: Jayce creates an electric aura dealing 40 / 55 / 70 / 85 / 100 / 115 (+25% of ability power) magic damage over 4 seconds.
Mercury Cannon: Jayce overcharges his cannon, gaining maximum attack speed for his next 3 attacks. These attacks deal 70 / 78 / 86 / 94 / 102 / 110% physical damage.
Which is incorrect, it deals that damage total over 4 seconds, not every second (He would deal 3000 damage with this ability every 6 seconds with 370 ap if this was true.)
Also, the cannon component to this skill has a separate cooldown, which i added at the bottom.
