I FINALLY DID IT!
I went with a balanced stats executioner build, doing high damage, and originally I thought I wouldn't have the damage to beat the final boss, but then I used hadad's third prayer and kept regening with lvl 2 bloodbath, I love the axe of transmuted rage, it may have no acc, but it rapidly triggers attacks, and that is much more important for my build. The final boss was also the only time I prayed the whole run, I use hadad for the storm of lightning and fire he makes.
couldn't find a good set of leggings or a better helmet so this is what I went with
