Black Flash is a plugin you may add to your server that grants players a chance of landing a juiced-up version of a critical hit. Black Flash is meant to replicate Jujutsu Kaisen's "Black Flash" mechanic in which a hit imbued with cursed energy within 0.000001 seconds of a physical attack multiplies the attack's power by an exponent of 2.5.
Similarly, the plugin applies a 0.001% chance of landing a black flash per each hit. Attack damage is multiplied by an exponent of 2.5, accompanied by red-text indicators and a red firework explosion when it successfully lands. Primarily made for PvP/PvE server events.
