# Stamina
Sprint too long and your body gives up. **Stamina** adds exhaustion to Minecraft with a cinematic, atmospheric take on running out of breath, from heavy panting to passing out.
## How it works
Sprinting builds up fatigue, shown as a ring around your crosshair. The longer you run, the worse it gets:
- **Red vignette, heartbeat, camera sway:** you start to feel it.
- **"You're tired, you're out of breath":** a warning with cinematic black bars and heavy breathing.
- **Blurry vision:** the screen turns soapy and smears harder when you turn.
- **Heartbeat dizziness:** every beat briefly blacks out your vision and jolts the camera.
- **Last 3 seconds:** loud ringing in your ears, muffled sounds, rapid blinking, tunnel vision.
- **You pass out:** darkness closes in, and you wake up at the next part of the day (day → evening, evening → night, night → morning).
## Consequences
Fainting is not free:
- Random penalty on waking: half your hunger **or** half your health (never below one heart).
- Hostile mobs nearby target you and hit extra hard while you are down.
- You may drop the item in your hand.
## Training
The more you sprint, the slower fatigue builds (up to 35%, 10 levels).
## Settings
Press the **Stamina** button in the main menu or pause menu. You can adjust timings, effect strength, volumes and text size, turn individual effects on or off, or pick a preset: **Easy**, **Realism** or **Hardcore**.
## Notes
- Does nothing in Creative and Spectator mode.
- Needs **Fabric API**.
- No shader pack required. The blur is built from vanilla effects and may look different with Iris shaders enabled.
- Sleep and penalty effects work in singleplayer and on the host or server; visual and sound effects are client-side.
