An effect (Java Edition, known as Mob Effect in Bedrock Edition) is a helpful or harmful condition that affects an entity. Effects can be inflicted in various ways throughout the game, including consuming potions and some food items, being in the range of beacons and conduits, and being attacked by or close to certain mobs.

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

Behavior[edit]

Any entities inflicted by an effect are affected in various ways for an amount of time. During the effect, spiral-shaped particles emanate from the position of the inflicted entity. For most effects, higher levels increase the strength of the effect.

In Java Edition, players can open their inventory to see any current effects afflicted upon them, as well as its level and duration. In Bedrock Edition, effects are displayed in a separate screen, which can be opened by pressing Z on a keyboard, pressing Back button/Touchpad/- button on a controller, or tapping the effect icon when using touch controls.

Internally, and in the /effect command and potion Amplifier NBT tags, the game stores an "amplifier" value, which is one less than the displayed level. For example, Strength II has an amplifier of 1.

Due to the way this amplifier is stored in NBT, amplifiers of 128 to 255 (levels 129 to 256) in NBT tags (e.g. on potions) are treated as if they were −128 to −1 (levels −127 to 0) respectively.‌[Java Edition only] The /effect command initially applies such amplifiers in their positive-valued sense but this is later converted to the negative-valued interpretation, leading to inconsistent results. In Bedrock Edition, amplifiers above 127 translate to positive levels, like other amplifiers.

Any number of different effects, including opposing effects such as Strength and Weakness, can be simultaneously active on a player. However, it is not possible to apply the same effect multiple times, even if they are of different levels (e.g. Strength and Strength II). When applying an effect already active on the player, higher levels overwrite lower levels, and higher durations overwrite lower durations of the same level.

In Java Edition, when the stronger effect then overrides the weaker effect, the weaker effect remains, but is hidden. It returns after the stronger effect expires, if the weaker effect has a higher duration than the stronger effect. This change makes it impossible to create custom potion antidotes by applying an amplified effect with a one tick duration.[verify]

In Bedrock Edition, when a stronger effect overrides the weaker effect, the weaker effect is deleted and does not return.[1]

Note that even with commands, effects cannot be made to last forever. If an effect is set to last a time greater than 32766 (215−2) ticks, 27 minutes and 18 seconds, or 1638 seconds, it displays as "**:**", but still continues ticking down and eventually expires.

All effects can be removed by drinking milk, dying, being saved from death by a totem of undying, or traveling through the return portal in the End. Singleplayer users with cheats enabled and operators in multiplayer servers can use /effect clear <playername>[Java Edition only] or /effect <playername> clear[Bedrock Edition only] to achieve the same goal.

Damage dealt by effects (a kind of "magical damage") completely bypasses armor, making it a good way to deal with highly-armored targets (Protection enchantments reduce damage taken from effects in Java Edition only). Witches are the only mob to have natural protection against effects, taking 85% less‌[Java Edition only] or 95% less‌[Bedrock Edition only] damage from effects, except Wither[verify].

Summary of effects[edit]

Positive effects have blue text in potion information, and in Java Edition are displayed on the upper row of effects in the heads up display, while negative effects have red potion text and are displayed in the bottom row. Neutral effects have the blue potion text and are listed with the negative effects in the bottom row in the heads up display.

Issues[edit]

Issues relating to "Effect" are maintained on the bug tracker. Report issues there.

Trivia[edit]

  • When having multiple effects, the effects' timers are reduced by 1 second each simultaneously, regardless of when the player took each potion. This is because they use the same "seconds counter" that "ticks" every 20 game ticks to save memory. For example, if the player drinks one potion and another different potion that doesn't reset the timer 5.5 (or any non-integer amounts) seconds later, both effects' timers subtract 1 second from both of them simultaneously.
  • When a creeper has an effect and explodes, it leaves an area effect cloud for each effect that it had before it died.‌[Java Edition only]
