[3.25] Fire Wild Strike Berserker in Progress and need help

Hey guys,

I have created an Fire Wild Strike Berserker but i have some issues to get a little bit more dmg on the build.

Does anyone have an idea how to get more dmg on this? The Calculation requires an pretty good sword, maybe you have a better Option.

Here is my pob: https://pobb.in/LfDbqp5fnwXq

Thanks for helping and best regards
