4/7 on Ragnarok. This one was a close call because I made a mistake and pushed her into the 2nd rage with the overdrive meter full (I realized as Mordred's Outrage activated that I'd made a big mistake). I ended up eating 2 rage overdrives in a row, one unmitigated, but I managed to push through it with only one death. As long as I don't have avoidable timing issues like that, it seems like I can reliably clear the fight.
