Onument's Survival Utils
by Onument
Onument's Survival Utils layers body needs, such as thirst, bladder, bowel cycles and fatigue, onto a Fabric survival game for 1.20.1.
What it does
Thirst and temperature are tracked alongside the usual health and hunger. Drinking water keeps a player hydrated, while water bottles boiled over campfires or furnaces become safe Purified Water. Freezing cold biomes and overheating in deserts or the Nether both have effects, and holding torches keeps a player warm. Cooled Armor protects against extreme heat.
Bladder and bowel functions are controlled with keys: a player holds B to urinate and N to defecate. Waste can be collected with an Empty Waste Bucket and smelted into Organic Fertilizer, which is far stronger than bone meal. Staying awake builds fatigue, shown as drooping eyelids, and emergency sleep beds can be used at any time when exhausted. Survival Settings opens an in-game menu, and the mechanic can be switched off at any time through the Escape menu.
The mod is a client and server environment, so the server and every player need it, and it works in singleplayer and multiplayer. Fabric API is required. Onument's Survival Utils is released under the MIT License and is not open source. Files exist for 1.20.1 only, with 1.0.0 as the latest, published 2026-08-18.
Key features

Water must be drunk to stay hydrated, and boiled bottles give a safe alternative to untreated water.

Fatigue and sleep
Staying awake causes fatigue, and emergency beds allow a player to rest whenever exhausted.
Temperature effects

How it compares
Thirsty - Thirst System is a Fabric mod for 1.20.1 that shares the client and server environment, but it is released under All rights reserved and is not open source. Smart Survival HUD is a Fabric mod for 1.20.1 that runs client-side only and is also released under All rights reserved, so it adds a display rather than the body mechanics. Extreme Dehydration is an open source Fabric mod under the Apache License 2.0 that covers 1.20.1 – 1.21.11 and also runs on both sides.
