Lightning Fury & ancients

I’ve been playing a lightning fury zon in single player. I got all the way to ancients, and now I’m stuck. Madawc is always lightning immune.

I tried using a lower resist wand, but it didn’t break it.
I could respec, but I only have 1, so would have to finish the game on that.
I could build obedience in a matriarchal spear, but would take a while to get a fal, especially since there are so many lighting immunes in the forgotten tower. I’m not sure how well jabbing with that would work anyway.
Guides recommend bugging the mercenary, But I don’t think that works now.
Could have another character give her a respec token, but my 2nd highest character is in act 3 nightmare.

Any suggestions?

Hello,

I finish the game with a poison/lightning build, i didn’t struggle too much in hell

Give your merc some crushing blow gear. You can also weapon swap to a high damage jav, maybe shop for some cruel javs and pound him together with merc…

Ended up making obedience in a matriarchal spear & jabbing him to death.

the plague javelin is so powerful, i had it maxed up now maxing up lighting fury . cant be stopped with those two
