The /effect command controls player and mob abilities such as speed, strength, invisibility, night vision, and regeneration. This generator helps you set the target, effect, duration, amplifier, and particle visibility without mixing up the order of command arguments.
Duration and Amplifier
Duration is measured in seconds for normal commands. Amplifier starts at 0, so Speed II uses amplifier 1. Testing low values first helps avoid broken movement or accidental one-hit damage.
Visible or Hidden Particles
Hide particles for clean adventure maps, stealth mechanics, and permanent buffs. Keep them visible when players need feedback that an effect is active.
Common /effect Questions
How do I clear all active buffs?
Switch the operation mode to 'Clear Status'. It's the fastest way to reset a player's condition - perfect for resetting arenas or fixing accidental God-mode glitches.
What's the absolute max level I can use?
Java Edition lets you crank intensity up to 255. Just be careful with 'Speed' or 'Jump Boost' at those levels - you'll end up clipping through the world or flying into the stratosphere.
Do these commands work on Bedrock?
Yes, but syntax varies slightly. Our lab detects your version and adjusts the command logic automatically so your potions work whether you're on a PC, console, or phone.
Can I buff my entire squad at once?
Absolutely. Use the @a selector to hit every player on the server, or @e[type=zombie] if you want to create a custom horde of super-fast undead.
Potion Command Tool
Minecraft Effect Command Generator
The effect generator creates /effect commands for Java and Bedrock players who need potion effects, amplifier levels, long durations, or quick clear commands without memorizing effect IDs.
Duration and amplifier notes
High amplifier values can create extreme movement, mining, damage, or visibility behavior. Test unusual values carefully because some effects feel different between Java and Bedrock or between client versions.
Quick questions
Can I make infinite effects?
You can generate very long duration effects, but exact behavior depends on edition and version.
What is an amplifier?
The amplifier controls effect strength. Level II is stored as amplifier 1, because Minecraft counts from zero internally.

If something feels wrong, a Minecraft version is missing, the wording is confusing, or you have a better workflow idea, send it over. Real player feedback is how these tools get sharper.
