yay, that helps a lot. I was getting worried because of the tooltip description, did I just read it incorrectly or is it worded badly?
StormStrike ToolTip: Instantly attack with both weapons. In addition, the next 2 sources of Nature damage dealt to the target are increased by 20%. Lasts 12 seconds.
That is taken from allas own spell lookup thingy.
(Not really a rant just curious)
