The effect command manages status effects on players and other entities.

  • Java Edition
effect <player> clear (removes all effects)
effect <player> <effect> [seconds] [amplifier] [hideParticles] (gives an effect)
  • Pocket Edition
effect <player: target> clear (removes all effects)
effect <player: target> <effect: string> [seconds: int] [amplifier: int] [hideParticles: bool] (gives an effect)
player (PE: player: target)
Specifies the target(s). Must be a player name or a target selector (@e is permitted to target entities other than players).
effect (PE: effect: string)
Specifies the effect to grant. Must be a status effect id (for example, 1 or minecraft:speed).
seconds (PE: seconds: int) (optional)
Specifies the effect's duration in seconds. Must be between 0 and 1,000,000 (inclusive, without the commas). If not specified, defaults to 30 seconds.
amplifier (PE: amplifier: int) (optional)
Specifies the number of additional levels to add to the effect. Must be between 0 and 255 (inclusive). If not specified, defaults to 0. Note that the first tier of a status effect (e.g. Regeneration I) is 0, so the second tier, for example Regeneration II, would be specified by an amplifier level of 1.
hideParticles (PE: hideParticles: bool) (optional)
Specifies whether the particles and the HUD indicator[Java Edition only] of the status effect should be hidden. Must be either true or false. If not specified, defaults to false.
Fails if arguments are not specified correctly, if player fails to resolve to one or more valid entities (named players must be online), if seconds was specified as 0 and the target did not have the effect, or if no effects were removed in clear mode.
On success:
  • clear — clears all status effects from the target(s).
  • effect — Adds the status effect to the target(s). If a target already has the status effect, a new status effect with the same amplifier will only override the old duration if it is longer, but a new status effect with a higher duration will override any previous duration. If seconds is set to 0, cancels the specified effect instead.
