I have previously drawn the comparison between a Duskruin Arena run and Reim (distinct stages, mini-boss at each & a major boss at the end), with longer duration and time for coffee breaks in between.

And I know that the Emperor/Empress pair, when you defeat them, will put you up into 'completely saturated' by some amount.

.

Would it be beyond the realm of acceptable if each of the lower-area bosses also had the capability to take you beyond 'must rest', up to 'completely saturated'?

Thanks!
