Longer Potions
Longer Potions extends the duration of beneficial potions, so a drink lasts many times longer than in vanilla Minecraft.
What it does
The mod targets only the positive status effects, leaving harmful ones such as poison, slowness and wither at their standard vanilla durations. Any drinkable, splash or lingering potion that carries a beneficial effect gets the longer duration, and the multiplier also reaches effects from beacon auras and golden apples.
It works by changing how the game applies an effect to a living entity, rather than editing tooltip text. The timer shown on the HUD therefore reads the modified duration and counts down at the normal speed. Because the check uses the beneficial category rather than a list of item names, potions added by other mods that have beneficial effects are covered as well.
The mod is a Fabric mod for 1.21.11 and needs Fabric API. A server running it needs every connecting player to have it too. The code is released under the MIT License, and the project is not open source in the sense of publishing its full source as a community project.
Key features
Longer positive effects
Beneficial effects from potions last several times longer, with the multiplier applied at the moment an effect is granted.
Coverage beyond potions
Beacon auras and golden apples gain the longer duration too, so the multiplier is not limited to bottled potions.
Harmful effects unchanged
Poison, slowness, wither and other negative effects keep their standard vanilla durations.
Compatible with custom potions
Potions added by other mods receive the extended duration automatically when their effects are beneficial.
