Effect



Status effects are various conditions that affect an entity, which can be either helpful or harmful. Status effects can be inflicted in various ways throughout the game, but are generally produced by potions.

The command allows players to inflict effects upon themselves and other players.

Behavior
Any entities inflicted by a status effect will be affected in various ways for an amount of time. During the effect, swirly particles emanate from the position of the inflicted entity. Players can open their inventory to see any current status effects afflicted upon them, as well as its strength and duration. The strength of the effect determines the power of the effect. The higher the levels, the stronger the effect is.

The maximum level an effect can have is level 127. Potions with any level higher than 127 would have a "corrupt" effect, or a negative effect; effects given by the command do not give the "corrupt" effect. Only a few "corrupt" effects actually cause a negative effect, namely Speed, Slowness, Haste, Mining Fatigue, Strength, Jump Boost, Hunger, Weakness, and Health Boost. Like any other normal potion effect, the effect completely wears off at the end of its duration. Unlike normal potion effects, potions with levels above 127 do not cause particle effects.

Any number of different status effects can be simultaneously active on a player, even in the case of opposing effects, such as Strength and Weakness. However, it is not possible to apply the same effect multiple times, even if the effects are of different levels (e.g. Strength and Strength II cannot both be active at the same time). In the event of applying an effect already active on the player, the new version of the effect overwrites the old effect, giving a new level and full duration, if the new effect is of equal or greater level.

Note that with commands, effects can be made to last forever. If an effect's time is set to 1,000,000, it will display as "**:**" and will not tick down or expire.

All of these status effects can be removed by drinking milk or using command with the time of the effect set to 0. For Singleplayer users with cheats enabled and operators in Multiplayer servers, command can be applied to achieve the same goal.

Trivia

 * After drinking a bucket of milk while under the Nausea effect, the screen will flash purple for a tick as if you were standing in a Nether Portal.
 * If the command /effect [player] [effect id] 0 is executed and the player already has that effect, the effect will be removed
 * If fog is turned off by a mod, Blindness is ineffective.
 * If you put Speed and Slowness together, you'll be able to sprint.
 * The maximum health the player can achieve using Health Boost and Absorption is 2068.
 * If you get max health using method above, and put regeneration level of 255, while healing to 2068 hearts, your view will jolt, even in creative mode, like getting hurt. You are not getting hurt though.
 * If you have at least resistance 5, then you are practically invincible. (Apart from the /kill command and the void)
 * Endermen inflicted with invisibility can still be seen due to the fact that the eyes still glow and a slight outline can be seen from a distance. Similarly, spider eyes will glow.
 * Strength level 127 is enough to slay an enderdragon with one hit from an iron sword.
 * The Wither effect is the only negative effect that can affect both living and undead mobs. It is also the only effect that can successfully damage Endermen when edited into splash potion form.
