How do you level stormweaver through the campaign?

i used spark and orb of storms through the campaign & it was a cakewalk. I used poe trade site along my journey to always have at least semi-good cheap gear equipped.

I did add electrocute support to it for a while to stun the entire screen, but then it got to the point where mobs were dying before they could get electrocuted so i swapped it out for more dmg

It is definitely not a cakewalk, i'm guessing you were carried.
