Overlord IV - Episode 11 - Albedo Flaps Wings

Albedo checked the strength of the attacks against her, but she was not impressed. It did not even harm one feather.

Ainz and Albedo personally attacked the strong enemies that could defeat Death Knights. The audience learned that a powerful entity was actively seeking "puh-layers." It also differentiated between them and "en-pi-shis." Albedo and Ainz were unharmed, but they successfully fooled the entity about their personal strengths. That wasn't even Ainz out there!
