Frequently Asked Questions
How do I give a permanent / infinite effect in Minecraft?
Enable the Infinite toggle in the Duration section. On Java Edition, this outputs the keyword "infinite" which displays as a ∞ symbol in the effect HUD. On Bedrock Edition, there is no infinite keyword, so the generator uses 999999 seconds (approximately 277 hours) as the practical equivalent.
What is the difference between the amplifier and the level?
Minecraft stores effect strength as an "amplifier" starting at 0. Amplifier 0 equals Level I, amplifier 1 equals Level II, and so on. This generator displays levels using Roman numerals (I through X) and handles the amplifier conversion automatically. You can also type any value up to 255 directly.
What does Hide Particles do?
When Hide Particles is enabled, the swirling particle cloud around the entity is suppressed. The effect is still fully active. This is essential for professional server and adventure map design where the particle cloud would break immersion or clutter the screen during boss encounters.
How do I apply multiple effects at once?
Configure each effect individually and click "Add to Stack" after each one. The Command Output panel will show all commands on separate lines. Copy them all at once and paste into a sequence of command blocks set to Chain or Impulse mode, or run them one by one in chat.
What are the new 1.21 effects like Wind Charged and Oozing?
These effects were added as part of the Tricky Trials update (1.21) and are granted by Ominous Bottles found in Trial Chambers. Wind Charged makes the entity emit a wind burst on death. Oozing spawns slimes on death. Weaving spreads cobwebs. Infested has a 10% chance to spawn silverfish each time the entity takes damage. All are fully supported in this generator.
How do I clear all effects from a player?
Switch to CLEAR mode using the tab at the top of the Settings panel. Select the target and click Copy Command. To clear all effects at once, the generated command is "/effect clear @p". To clear one specific effect, select it in the left panel first before switching to CLEAR mode.
