Effect

An effect (also known as a mob effect or status effect) is a condition that affects an entity, either negatively, positively, or neutrally. Effects usually can be inflicted in various ways throughout the game, including potions, some food items, being shot by certain arrows, being in the range of active beacons and conduits, and being attacked by certain mobs.

The /effect command allows players to inflict effects upon themselves and other entities with different levels of these effects.

Entities inflicted by an effect experience various changes either instantly or for a duration of time. For most effects, higher levels increase the potency of the effect. As long as the effect is active, effect-dependent particles emanate from the position of the inflicted entity. Effects provided by beacons and conduits emit semitransparent particles and are known as "ambient".
