Be prepared for a tough battle when you enter the room in the center of the 10th basement floor, as you will have to face both Deep Lady and Deep One simultaneously.

To increase your chances of success in the battle against Deep Lady and Deep One on the 10th basement floor, it is important to focus your attacks strategically. Deep Lady should be targeted with physical attacks, while Deep One is vulnerable to elemental attacks. However, be aware that Deep Lady can use the “Dis-Element" skill, rendering your elemental attacks ineffective. To counter this, use items such as “Ice Mist" and “Laudanum" to remove the Dis-Element effect, or employ the Sovereign’s skill “Ad Nihilo" to nullify it. If Deep Lady’s head is bound, Deep Lady will not be able to use her skills. Additionally, putting Deep One to sleep can be a helpful tactic.

Avoid selecting the option “Attack it, quickly" after defeating Deep Lady and Deep One, as it will trigger another battle against them. Instead, choose a different option to proceed without engaging in another fight.
