Kassandra travelled to the Sinkholes of Herakles in Argolis, finding the lion at its lair, along with its pack mates.
Kassandra:King of beasts.
Kassandra entered the lair and engaged the lion and its pack, eventually killing them. She recovered its pelt and returned to Daphnae at the Temple of Artemis in Phokis.
Daphnae:Beast Slayer, I'm glad to see you again.
Kassandra:The Nemean Lion's pelt.
Kassandra handed the pelt over to Daphnae.
Daphnae:Magnificent, as is its hunter.
Kassandra:Strength is powerless in the face of beauty. Even Herakles fell to its sway.
Daphnae:You slay me as easily with your words as your weapons do these beasts.
Kassandra:You haven't seen anything yet.
Kassandra got closer to Daphnae and shared an intimate moment.
Outcome
Kassandra found and killed the Nemean Lion, recovering its pelt for Daphnae. In return, she received Pandora's Kopis as a reward.
