help me do damage

This is the PoB of my Tornado Shot char.
Do you have an idea how it can do damage?
I use legacy Death's Opus
I want to play a char with Death's Opus and Tornado Shot
I know that I am missing damage on the jewels and the acessories, but that alone won't fix the char.
Is there any aura that would work good? At the moment I only use Vulnerability to support my damage.
Passive tree has low damage

Next problem will probably be that I dont have any defenses besides Life pool and basic resis.
I would appreciate a link to a build that can be played with Death's Opus.

I made an Ice Shot char, it has better damage.
