AlchemyPlus
A Minecraft Mod that adds a brewing minigame to make brewing more fun. Also that minigame can multiply duration of your potions

A NeoForge mod for Minecraft 1.21.1 that adds a brewing minigame to make potion crafting more engaging.
When brewing starts, a minigame window opens. Hold left mouse button to move the indicator upward — try to keep it inside the moving zone. The longer you stay in the zone, the higher the potion quality.
Potion duration is affected by your performance: anywhere from 50% (poor) to 150% (excellent) of the base duration.
config/alchemyplus-common.toml
From this config you can change the minigame difficulty for your server.
