Ninja's Twofoldblade Skill

Hello Fellas!
Here is a guide on how to level up twofold blade really fast... When using fatal strike, also try to use twofoldblades to hit the monster.... this would give really high skill exp though it dealt less damage.... Hope this helps...

Easier way go afk and cast twinfoldblade on a stack that is 5 levels below the stack you should be hitting i.e if your 110 do it on 105 stacks you will have it maxed out in under a couple hours.
