Redstone extends duration where supported; Glowstone strengthens an effect where supported. Some potions cannot use both choices.
Quick answer
Use the correct base, effect ingredient, and supported modifier. Read the output name before taking the potion.
What to do
Work through these checks in order. Stop if a menu, command, or world state differs from the conditions described.
- Confirm your Minecraft edition and release, then identify the world, device, or server involved.
- Check whether the selected potion supports extended or enhanced form.
- Add one modifier to a test brew and compare the output name and duration.
- Check the result in the game. If it differs, record the exact error or menu label and compare the official source for your version.
Edition and version differences
Effect availability and modifiers can change by edition or release. Check the brewing-stand output after each ingredient.
If the result differs
Compare the current screen or error text with the conditions above. Use the correct base, effect ingredient, and supported modifier. Read the output name before taking the potion. Change one variable at a time so you can tell which step made a difference.
