Just a heads up to moonkins not aware, you only receive the buff to starsurge after your wrath hits the target. It's a bit of an annoyance. IMO the buff should be gained upon a successful wrath cast.
As it stands now, if you cast wrath -> starsurge. That starsurge will not benefit from the trait.
If you're casting multiple wraths to build AP for a starsurge this won't effect you. But if you are weaving between Empowered Lunar Strikes and Empowered Solar Wraths, you'll want to cast Wrath -> LS -> Starsurge instead of LS -> Wrath -> Starsurge.
