PotionCoreX
I made PotionCoreX because I wanted a potion stacking plugin that does more than just stack potions.
For me, the most important part was always brewing safety.
A lot of stackable potion plugins can make potions stack, but the real problem starts when hoppers and brewing stands are involved. If stacked bottles are pushed into a brewing stand like normal stacks, brewing can break, bottles can behave strangely, or automation becomes unreliable.
PotionCoreX solves that by handling brewing stand automation safely.
Even when potions or water bottles are stacked in inventories and hoppers, they are fed into brewing stands one by one, exactly the way they should be for stable brewing behavior.
Why I made it
I tested a lot of potion stacking solutions before building this one, and the biggest issue was never just the stack size itself.
The real issue was everything around it:
- brewing stand safety
- hopper automation
- inventory behavior
- applying new stack sizes cleanly
- making the whole thing practical to manage in real gameplay
That is why PotionCoreX focuses on safe and clean behavior first, not just on making potion stacks bigger.
Main features
- Stackable normal potions
- Stackable splash potions
- Stackable lingering potions
- Stackable water bottles
- Stackable base potions
- Brewing-stand-safe hopper behavior
- One-by-one bottle insertion into brewing stands
- In-game settings GUI
- Preset system
- Multi-language support
- Update checker
- bStats support
Brewing and hopper safety
This is the most important feature of PotionCoreX.
PotionCoreX does not just allow potion stacks. It also protects brewing automation by making sure hoppers do not dump full stacks into brewing bottle slots.
Instead, bottles are passed into the brewing stand one by one.
That keeps brewing stable and prevents the usual problems that happen when stacked bottles are handled like normal items in brewing systems.
If safe brewing automation matters to you, this is the core reason why PotionCoreX exists.
In-game settings GUI
PotionCoreX includes a settings GUI so I can change potion stack sizes directly in-game without editing files all the time.
I can adjust the different potion categories, save the settings, and apply them directly.
Presets
I also added a preset system so I can create my own setups and load them again later.
That makes it easy to switch between different stacking styles without rebuilding everything by hand.
Languages
PotionCoreX includes multiple languages and lets me switch them easily.
Included languages:
- English
- German
- Spanish
- Italian
- French
