Short dash that grants AS +deals dmg, passing through allies doubles the range+dmg, and shares AS
I feel an Ability like this would be good to add to the game via upcoming reworks or new champion.
The range would be slightly longer than a Riven E with similar speed but different effects.
On cast it would grant 20-40% AS, and on contact with enemy it deals x amount of damage(120+70% AD?)
Passing through allies doubles the range and damage to enemy's hit afterwards(240+140% AD?) and applies the Attack speed buff to them.
I feel this is a very healthy mechanic, rewarding skill and teamwork like a boss.
