I recently spent a few hours in Sky along with blowing a bit of cash to try and get to the hand in without clearing.

You cannot jump to 4th isle from zone in (isle 1). I was not able to jump to 4th isle from Noble (isle 2). Couldn't get Gfluxed high enough to make the jump either. Was going to try a knockback proc from a staff but canned that when I couldn't get anyone to give me a hand with that.

Ended up taking one group over to Azaracks (isle 3) and just cleared it. Two groups would be easier; we wiped once after getting half the isle clear but were easily able to finish after the CR.
