Me too. It should be easy enough. Blink to the left, swing three times, turn slightly right, blink again, swing four times and then blink again.

I haven't tried anything like this, is there a recharge interval for blink?

If you are on the ground, you are able to blink jump twice in quick succession. After that, there is an invisible cool down, usually about two/three seconds before you can use blink jump again. It appears swinging the sword in the air has the same rules applied as if on the ground with blink, so keep that in mind. Practice makes perfect. Good luck friend.
