"Flash:

Speed Force
When the Flash uses a skill he gains a stack of Speed Force. Speed Force grants him 2.5% Move Speed for 2.5s, and can stack up to 5 times.
The Flash gains Bonus Damage (+1% per 10 Bonus Move Speed) based on his Bonus Move Speed, currently granting 0.1% Bonus Damage.
Move Speed: 2.5% / 3.5% / 4.5% / 5.5%

Flash Attack
The Flash rushes to target location, dealing 60 Attack Damage to all enemies he passes though. The base cooldown of Flash Attack is reduced if he rushes less than Flash Attack's maximum range, down to a minimum of 40% at half range.
If Hyper Vibration is active, this skill changes to a dash and can pass through walls.
Damage: 60 / 95 / 130 / 165 + 90% Bonus Attack Damage
Cooldown: 9
Cost: 25 / 40 / 55 / 70

F=MA
Resets Basic Attack cooldown. The Flash's Basic Attack speed is set to 3 per second for 3s or until he uses 4 Basic Attacks. During this time, the Flash's Basic Attacks deal only 25% damage, but each hit deals an additional 20 Attack Damage.
F=MA's attacks apply Hit Effects, but the bonus Attack Damage does not apply to structures.

Cooldown: 10 / 9 / 8 / 7
