This vigilante typically does not follow any code except her own, but the boss offered Nadia a deal she could not refuse. In exchange for a pardon on all of her past misdeeds, Nadia must gather intelligence on all of the city's heroes and villains. Once the boss has this intelligence, it will be used to determine allies and foes in the new regime.
Each mastery level adds another card to the cardpool for defeating Nadia. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
