Big Bang Age:Dungeons

There are dungeons scattered across the map that can be explored for experience, items, and regional income. Certain character recruitments and clears also require exploring dungeons. You enter each dungeon with a party of up to 6 characters and fight a series of battles, with the option to retreat after every floor. If you retreat, you will return to the map in the Region Phase as normal, and you will continue from the floor you retreated from the next time you enter the same dungeon.

Stamina and HP do not naturally recover between battles. To deal with this, you have a few options: First, certain abilities restore stamina in-battle, the most relevant one being Gyver Mac's. Second, healers (Sonnet and Sayuri) will restore HP based on each unit's current HP between each battle, but Senna's Super Recovery does not activate between battles. Finally, if all enemies and allies run out of stamina, everyone will recover 1 stamina. Note that this is fairly difficult and dangerous to pull off, especially since characters without stamina cannot dodge. Try to plan ahead and be ready to retreat before you end up in a situation where characters die.
