Here's the final update on my Dex stacking LS Wildspeaker build I made in Phrecia Event. Its been really fun and one of the strongest builds I've ever played. It can do all content easy, I'm just watching youtube on the second screen while blasting very hard content.

Degens are the only weakness, but they are definitely doable. As long as you deal damage you can stand anywhere very safely, just move to safety when there is no monsters left.

In the final version Determination aura is not necessary, you can pretty much use whatever aura you like depending on your playstyle and the content you do. The build feels extremely tanky even without Determination. In the showcase videos I used Haste because I like to be fast.
