Clash of Faith Proudclad Apocalypse + 220 Final Fantasy Record Keeper FFRK Champion

This boss was ridiculously tough. I had to spend a few mythril to get the 10% offense and defense bonus.
RW used was Shantotto's Chain Soul Break.
The Jump Start (Full Throttle) version of this fight is so much easier.
