You can fast travel to the stairs and reach the next floor
As you’re traveling through each floor of Tartarus, your goal will be to find the stairs that lead to the next area. However, if you find them early in your search, don’t head up right away; there’s still plenty of enemies to fight, treasure to find, and ambient dialogue to hear on that floor. Luckily, if you open the map after finding the stairs, you can immediately fast travel to the next floor from anywhere. So don’t be afraid to explore some more before heading up.
