Effect
An effect (also known as a mob effect or status effect) is a helpful, harmful or a mostly useless 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 active beacons and conduits, and being attacked by or close to certain mobs.1
Behavior
Entities inflicted by an effect are affected in various ways for an amount of time. For most effects, higher levels increase the strength of the effect. As long as the effect is active, spiral-shaped particles emanate from the position of the inflicted entity. Effects provided by beacons and conduits emit semitransparent particles.
Any number of different effects, including opposing effects such as Strength and Weakness, can be simultaneously active on an entity. However, it is not possible to apply the same effect multiple times, even if they are of different levels. When applying an effect already active on the player, higher levels overwrite lower levels, and higher durations overwrite lower durations of the same level.
A player can remove all of their effects by either drinking a milk bucket, dying, or being saved from death by a totem of undying. Poison can also be removed by drinking a honey bottle.
Any damage dealt by effects is classified as magic damage and completely bypasses armor, making it effective at harming highly-armored targets. However, the Protection enchantment does reduce the damage taken from effects.1
