Potion Blender Mod (1.21.1) – Merge Potion Effects Into One Item

Brewing in vanilla Minecraft feels limited once you realize each potion only carries a single effect. Potion Blender Mod changes that by letting you merge up to three potion effects into a single bottle, opening up creative combinations that vanilla simply doesn't allow. With over 28,000 downloads on Modrinth and active development since mid-2023, this lightweight addition by motivational_dragon has quietly earned a loyal following among potion enthusiasts and PvP players alike.

Key Features

• Combine up to three effects in one brew — Stack different potion effects into a single item, cutting down on inventory clutter and letting you drink one bottle instead of three.
• Custom blending cauldron — Right-click a campfire or soul campfire with a vanilla cauldron to create a modified cauldron specifically designed for blending potions.
• Normal, splash, and lingering variants — The final ingredient you add determines the potion type, giving you full control over how your blended brew is used.
• Multi-effect tipped arrows — Combined lingering potions can be crafted into arrows that apply multiple effects on hit, a serious advantage in combat.
• Stackable durations with diminishing returns — Adding the same effect more than once increases its duration, though each additional stack contributes less than the last.
• Datapack support for custom recipes — Players and modpack creators can define their own blending recipes through datapacks, extending the mod beyond its default combinations.
