BlackFlash Mod

BlackFlash adds a rare, high-impact critical strike to Hytale combat. Each player attack has a configurable chance to trigger a Black Flash, multiplying damage, playing a custom sound, showing a HUD notification, spawning blood particles, and displaying a custom hit-splat that shows the Black Flash damage value.

This mod is server-side and uses a JSON config file to let you tune the experience.

Features

Chance-based damage multiplier on player attacks.
Custom HUD notification (icon + text) when a Black Flash occurs.
Custom hit-splat showing the Black Flash damage value.
Optional sound effect on Black Flash.
Blood particle burst with configurable red/black mix.
Optional health and stamina recovery on Black Flash.
Streak multiplier: consecutive Black Flash hits scale damage even higher.
Colored streak chat message to the player when a streak continues.

Recommended Dependencies

To get the full experience, the MultipleHud mod is highly recommended. It helps ensure the custom HUD elements from BlackFlash display properly alongside other UI elements.

Streak Multiplier Example

With streakMultiplier set to 1.0, the streak scaling works like this:

Damage 20 = 20
Damage 20 + Black Flash = 20 x X
Damage 20 + 2 Black Flash in a row = 20 x 2 x X
Damage 20 + 3 Black Flash in a row = 20 x 3 x X
And so on…
