Archer/Hunter Help Thunder/earth Cluster Build?

So i just thinking about a thunder/earth build and then this just came in My mind "How fun could a thunder cluster will be..."

The main heart of this build is spamming the shit tons of arrow storm while doing a good amount of melee damage
All of the stuff i can think right now that will fit this build is Cluster with 3thuder powder and 1earth powder and soul sognal :v
I need help with other stuff
Thanks!
Sorry I'm not a good english speaker and don't really know what to write to make it a good thread :/

I think a raw spell samage might be good for this build

Oh and some mana regen would be nice too

 

The best earth/thunder bow at the moment is petrified horror.

 

Yeah i know but i want a weird build +i like cluster so i came up with this :)

 

Nice tags.
