Bladestorm and multistrike

How does multistrike work with bladestorm? like if I use bladestorm for three times, what's the damage and speed multiplier of storm 1, 2 and 3 when it's supported by multistrike support?
Thanks

Multistrike will support Bladstorm in the same way that it would support other melee skills. Comparing a Level 20 0% Quality Multistrike to 3 attacks without:

1st attack: 44% more Attack Speed, 20% less Damage
2nd attack: 44% more Attack Speed, (0.8*1.22=0.976) 2.4% less Damage
2rd attack: 44% more Attack Speed, (0.8*1.44=1.152) 15.2% more Damage

Overall, an average of (0.8+0.976+1.152)/3 = 2.4% less damage, but you get 44% more attack speed.

Understood
Thanks
