Oracle Double Comet - how can I get more Damage

Here is my current pob.

Wondering what I can improve to get more damage?

Working on getting a new ammy and replace helm with the vertex.

What else can I work towards?

Just finished my temple, full 77 room fubgun layout and want to carry that with 6 players but need more damage.

Thanks
