I was too shocked to take a screenshot of the -160000 health, but I shoulda. The source was Rozuel on floor 4--if you chip her down past 30 she'll hit you with a 20% mortal poison drop for 5 floors. It burned me 2 floors later. So yeah, maybe avoid that in the future. I actually died the next round as well because for some bizarre reason I couldn't manage to hit 7 combos on Andromeda... for like 3 consecutive turns...leaving Fio's damage output woefully short. Shame on me. On to the 10th round.
