I found a use for it... it stacks with the +2 crystals ability and if you farm crystals on a lower lvl node (I went into heavensward areas for lightning crystals) you'll see a quick rate of acquisition. Using both on a node with +1 or +2 gathering swings, I was getting 5 per hit so 25 to 30 crystals from those nodes, 20 from a standard 4-hit node.
