Following beta 3 gathering nodes were nerfed to have fewer attempts per node. However, the "Deep Vigor" ability was not adjusted accordingly, and it only activates on chain #4, which is 100% unattainable except on levequests, where the number of attempts per node was not reduced (otherwise they would have had to modify all the levequest objectives). However, there are no HQ items on these levequests, and the items are all specially for the levequest and can't be kept anyway.

This ability needs to be adjusted to work after chain 3, or it can never, ever be activated in normal gathering. Even then, it would only be able to be activated on nodes with +1 gathering attempt. I realize that the chain requirement is to keep the ability from being too good, but if it can't be used at all, then it has no point in existing.
