I don't know if Deathgaze works that way, though. Isn't he usually in a specific square based on your total time? So, no matter how many times you reset, if you weren't at the right time, he may not be in your path to the next place? Maybe I have that wrong, but I had problems even finding Deathgaze to fight once a few years ago, and I got that info in some of the advice that was given to me.
