Build advice requested

Hello,

I've been playing my pathfinder this season with galvanic shards!
I tried different version of my current build, i started out with "normal: galvanic shards and now i am using a version that chains additional times for hilarious off screen clear!
My wave clear is AWE-some!

For boss killing ive used different things.. i started out with stormcaller arrow and than shockburst rounds..
After a while i switched to plasma blast and shockburst rounds combo.
At this point i use stormblast bolts in combination with mirage archer which is pretty effective but doesnt always consistantly kill a boss fast (sometimes the boss is dead in 2 hits of my mirage, sometimes it takes 10-15 seconds).

My biggest annoyance at this moment is the headhunter.. im really cursed and after 2 elites im already stuck with shroud walker and it always teleports me at the worst times...

So im currently looking into a bit more conisestent boss killing potential and a way to get rid of headhunter..

Sadly i dont really know how to fix this puzzle at this point.. the headhunter also gives me some stats i really need.. I did have a look into a good ring, a copy ring and a ingenuity belt..

this is my current build and i have around 500div to spend on the build...

Any good suggestions where to go from here?
TIA!
