Required hero: Princess Celestia
Enemy: Nightmare Moon
Luna: There can only be one Princess in Equestria. ME!
Celestia: Luna, NO!
Luna: Luna? I'm Nightmare Moon! (she transforms and starts the fight)
Celestia passive: Luna, NO! - Celestia is hesitating to hurt her little sister, so your attack and accuracy are greatly reduced.
Nightmare Moon passive: Flammable - any fire or energy attack will trigger an explosion on her, causing extra damage and Burning.
Enlightened Iso-8 - Heals allies when protecting them. In her presence, attacking a Burning target heals the attacker.
