Adrenaline Effect
by alexdesander
Adrenaline Effect gives a player a short burst of speed, jump height and mining speed once health drops low, through a new status effect with a cooldown.
What it does
When a player's health falls to a low level, the mod applies a new Adrenaline status effect automatically. While it lasts, the player moves faster, jumps slightly higher and attacks and mines more quickly. The effect only activates at low health, and a built-in cooldown starts when it wears off, which blocks a second trigger straight away so the boost cannot be used continuously.
The mod adds no items and no complicated systems. Built for survival play in vanilla, it works as a final-chance mechanic during fights and travel, so low-health moments call for more active decisions. The author recommends it for Ultra Hardcore worlds. It is a Fabric mod for Minecraft 1.21.10 only, and it is open source under the CC0 1.0 Universal license, so its source code is public.

What the author says
Adds a new Adrenaline status effect that automatically triggers when your health drops to low HP, giving you a brief burst of power with a built-in cooldown. After Adrenaline wears off, a cooldown prevents it from triggering again immediately, so it cannot be abused in continuous combat.
