About this Mod
A lightweight, highly optimized Fabric mod designed to significantly extend the duration of beneficial status effects in Minecraft.
Core Features
Selectable Multipliers: Just like choosing the right dosage for a specific need, you can select how strong you want the buff to be. Available in 3x, 5x, and 10x strengths. Simply navigate to the Versions tab and download the specific multiplier file you prefer.
Universal Application: Natively extends the duration of Drinkable, Splash, and Lingering potions.
Beyond Potions: The multiplier automatically applies to other beneficial effects, including Beacon auras and Golden Apples.
Balanced Design: Exclusively targets positive status effects. Negative debuffs like Poison, Slowness, or Wither are completely ignored and remain at their standard vanilla durations.
Technical Details
Platform: Built natively for Fabric 1.21.11.
Injection Method: Utilizes Mixins to intercept the MobEffectInstance at the precise moment of application on the LivingEntity.
UI Synchronization: By modifying the core application logic rather than altering tooltip text, the mod ensures that your on-screen HUD timer reads the correct modified duration and counts down at a standard, accurate speed.
High Compatibility: Instead of hardcoding specific vanilla items, the code targets the overarching MobEffectCategory.BENEFICIAL flag. This means it should automatically work with custom positive potions added by other mods.
Installation
Download your preferred multiplier .jar from the Versions tab and place it into your mods folder. Ensure you have the standard Fabric API installed.
