"  Abaddon's basic attacks grant him bonus attack speed equal to 10% of the physical damage dealt for 4 seconds. Striking champions will cause this effect to stack. "

I don't understand how it works, let's say i deal 100 dmg, 10% = 10. How much will my attack speed increase ? with a flat 10 (wich i higly doubt LOL) or +10% ?
