Step-by-step guide

How to use the Effect Command Generator

Select Java or Bedrock Edition and enter the target selector.
Enter the effect identifier, duration in seconds and zero-based amplifier.
Copy the generated edition-specific command and test the intended level.

Calculation

Formula and game rule

Java uses /effect give <target> <effect> <seconds> <amplifier> true; Bedrock omits the give subcommand in this base form.

Worked example

Example result

An amplifier of 1 means effect level II, so Java speed II for 30 seconds uses amplifier 1 rather than 2.

What to check before using the result

Amplifier is zero-based: 0 is level I, 1 is II and 2 is III.
Very high effect levels may render incorrectly or cause behaviour outside ordinary survival gameplay.

Java and Bedrock Edition

The generator switches the base command grammar between Java and Bedrock; effect availability and limits can still vary by version.
