About this Mod

JJK BlackFlash Addon

English

This is a simple addon for the JujutsuCraft mod.
It makes every attack (including cursed techniques and player's summons/shikigami) count as a Black Flash.

Whenever you hit an entity, it will trigger the Black Flash visual effect and deal increased damage (default ×2.5, configurable), simulating a confirmed Black Flash every time. It also automatically applies the Zone effect and clears fatigue.

New in v1.2.1:

  • Summons Support: Your tamed Shikigami and summoned Cursed Spirits can now trigger Black Flash (Configurable).
  • Effect Intensity: You can now adjust the amount of Black Flash particles/effects (Configurable).

Installation:

  1. Install Minecraft Forge 1.20.1.
  2. Install JujutsuCraft mod.
  3. Drop this jjk_blackflash-1.2.1.jar into your mods folder.

日本語

  • 召喚獣の対応: プレイヤーがテイムした式神や召喚した呪霊も黒閃を出せるようになりました(コンフィグでON/OFF可能)。
  • エフェクト量: 黒閃のエフェクトの量をコンフィグで調整できるようになりました。
