FroSS Suggestions Needed!

Hello Everyone,

I just switched to the FroSS build, using around 10-12 div.
Here is the PoB:

Some of the attributes were not imported properly. But this is the current build.

How can I upgrade the defense/damage for the same? What are the upgrades I can do to this?
I have around 15div left to make any changes.

Thank you in advance.
