Darkness
From Chrono Wiki, a database for the Chrono series that anyone can edit
Darkness is a negative Status Effect in Chrono Cross that lowers the victim's hit rate, thus causing them to miss physical attacks more frequently than usual. It can be inflicted via HellSoul only if its instant death attack does not work. As a Black effect, it can be cured using the 2nd-level consumable Black element, BlackOut. It can also be cured with the fourth-level White consumable Panacea (Element). This status effect will go away automatically after the battle ends.
