I came up with this idea when I was playing Red Alert 2 and 3. I observed how prism towers function and I borrowed the idea of light refraction. This is the result champion.

Bibbo The Laser Gunner

Bibbo is a ranged yordle champion. His main role is marksman (I hate the word but hell, go with the flow). He is designed to poke enemies using his Refraction turret and to zap them from a range. His ultimate can turn the tide of a battle. There is a lot of focus in his Refraction turret since it will change all of his abilities if then interact with it.

Melting Point
Every 4th consecutive basic attack on the same target will burn 10%/15%/20% of their total armor and magic resist for 3 seconds. When this occurs the effect can't occur on the same target for the next 8 seconds. Also, Bibbo's basic attack don't have travel time (lasers are cool, speed of light and stuff).

Refraction Turret Callback
(Active): Bibbo throws his Refraction turret from the back in the target area. Upon landing it will slow by 50% enemies that are caught in the landing zone. Enemies and allies can use movement displacement abilites to move the turret. Upon second activation the turret will teleport back to Bibbo. If Bibbo goes out of range, turret will automatically teleport back to him.

Improved Recall mastery 2012.png
Laser Cannon
(Active): After a brief delay, Bibbo locks onto a target enemy champion or Refraction Turret and channels for 2 second. While channeling, Bibbo gains true sight of the target. If Bibbo completes the channel, a laser from the sky will obliterate the 300 units area after a 0.5 second delay, dealing damage to all the champions. Enemies who are away from 300 unit epicenter but withing 300-500 units area will take 50% reduced damage. If Bibbo locks on the Refraction turret, turret will relay the beam onto nearest enemy champions withing 700 unit range spliting the beam AND DAMAGE at the number of champions. Bibbo can also target himself if he is in the possesion of Refraction turret.
