I had never before attempted a serious go for beating the timer in this dungeon. That was because I had not quite learned how to handle 1st and 2nd boss without having any accidental wipes or early deaths.
I also tried if it was possible to skip some pack of mobs which I find particularly annoying. Turns out I skipped a bit too much and had to run back for some trash.
