A Tragedienne casting BlackRain on her opponents during a Grand Slam tournament.
BlackRain (呪いのシャワー , Noroi no shawā, lit. Cursed Shower?) is a Black Enemy Tech used by Man-At-Arms and Tragediennes in Chrono Cross. This tech enables the user to cast a dark spell, which showers said user's foes with a black-colored rain, inflicting both damage and the Cursed status.
The user in question will gather dark energy orbs in its hands, which explode with an ominous glow. Black-colored rain droplets will then fall from the sky, smattering the foes relentlessly for a short period of time.
