I tried several times for my passive skill shadow build. I plan to use bow and probably lightning elemental damage. This is my planned passive skill tree for the moment.

I plan to take several health nodes and elemental resistance but mostly will be about damage, attack speed and several elemental damage nodes.
Any comment, feedback, revision will be very appreciated.
