ORB WALKING

Yesterday, i just learned one thing, n that one thing is call ORB WALKING... What is orb walking... a few websites, suggest that orb walking is using unique attack modifier to hit an enemy heroes, to harass, and to prevent enemy heroes getting gold or last hit...

So how to orb walking?
You dont bring orb, and walking..You dont do that... You do this :

1. Instead hitting enemy heroes usual way with right click, you use left click after clicking your spells that count as Unique Attack Modifier.. ( Clinkz got Fire Arrow, Drow got Frost Arrow ) DONT AUTO CAST. The one that you click once...

2. So when the animation of hitting enemy in progress, let say Clinkz hitting enemy heroes using his Fire Arrow, you either can walk towards or backwards in the same time when you cast... than you repeat back steps one if you wanna hit more..

They say orb walking is dota 2 basic.. i just learned it.. so whats the point of orb walking?

1. You hit free, without creeps getting in your way...
2. You hit faster, without waiting the casting time to end..
3. You may hit before you run... ( HIT and RUN ) before enemy heroes able to do anything..

Got it?
