User blog:Nuclrdmntr/Hexragon, The Hextech Gunner

Hello, I'm here with yet another custom champion. Feedback is greatly appreciated!

This one is another attempt to create a unique game mechanic by essentially giving him a 5th ability instead of an autoattack. This champion is supposed to be driving a tank with a large hextech cannon and multiple other forms of weaponry. It's partly based on the Soviet Apocalypse tank in Red Alert 3 as well as the Ion Cannon in the Command and Conquer series.

Passive: Hextech Cannon

Hexragon does not autoattack. Instead, he charges his cannon for up to 2 seconds upon right-clicking on a champion and fires a bolt of energy that deals +2/AD +1/AP magic damage. This applies on-hit effects.
 * Cooldown: 6, 5, 4, 3
 * Range: 1000

Q: Emergency Discharge

Fires his cannon early, dealing a % of the total damage based on the channel time. This ability shares his passive cooldown.

This ability is available at level 1.
 * Minimum damage: 10%, 20%, 30%, 40%, 50%, 60%

W: Missile Barrage

Fires a missile at the target location, expending 1 missile and dealing 30, 60, 90, 120, 150 +0.35/AD +0.2/AP physical damage. He stores a certain amount and gains one every 15, 13, 11, 9, 7 seconds.
 * Cooldown: 0.5
 * Cost: 1 missile charge
 * Range: 1200
 * Radius of explosion: 150

E: Hextech Shredders/Gravity Harpoon

Passive: All enemies in a cone in front of him get damaged for 20, 35, 50, 65, 80 +0.5/AD +0.25/AP physical damage per second. Active: Launches a gravity beam. The first unit it hits will be dragged to his front, rooted for 0.25, 0.5, 0.75, 1, 1.25 seconds and slowed for 1 second afterwards.
 * Range: 250
 * Angle: 60 degrees
 * Range: 1000
 * Cooldown: 21, 19, 17, 15, 13

R: Skycannon

After 1.5 seconds, he calls down a beam of energy dealing 150, 250, 350 +1.2/AD +0.6/AD magic damage in an area. Over the next 3 seconds, it does 50% of the initlal burst in 50% of the initial AoE per second and it can be redirected within 1750 range of Hexragon.
 * Cooldown: 60, 45, 30
 * Range: 1750
 * Radius: 350
