What status effects are
Status effects are temporary conditions that change how a player or mob behaves. One can make you sprint faster, another can drain your health a half-heart at a time, and a few do nothing on their own until something else happens. Most of the game’s potions, several foods, a handful of blocks, and a long list of mobs all work by handing out these effects.
If you have ever chugged a potion before a fight, eaten a golden apple in a pinch, or watched your screen go dark near a Warden, you have already used the system. This guide covers how status effects work under the hood, every place they come from, the full beneficial and harmful lists, and the fastest ways to get rid of one you don’t want.
How status effects work
Every active effect shows up as an icon in the top-right corner of your inventory screen. Hover over it and you see the effect name, its level, and how much time is left. Three things define any effect: its type, its duration, and its amplifier.
Duration
Most effects run on a timer measured in seconds. When the timer hits zero, the effect ends. Drinking a longer potion of the same effect refreshes the timer rather than stacking a second copy. A small group of effects skip the timer entirely and fire once the moment they are applied. Instant Health and Instant Damage are the two main examples, which is why a Potion of Healing works the instant you drink it.
Amplifier, or the effect level
The amplifier is the strength of the effect, shown as a Roman numeral after the name, like Speed II or Strength I. A higher level means a stronger result: Speed II moves you faster than Speed I, and Regeneration II heals you quicker. When you use the /effect command, the amplifier number starts at 0, so an amplifier of 0 is level I, 1 is level II, and so on. That off-by-one quirk trips up a lot of people building command-block contraptions.
Particles and icons
Active effects usually give off colored particles that swirl around the affected entity. Each effect has its own color, so a green haze means Poison while a pale blue cloud often means Speed or Water Breathing. Potions brewed with a redstone extension last longer, and effects applied from beacons show up as “ambient” with fainter particles. You can hide particles entirely with the /effect command if you prefer a clean screen.
Where status effects come from
Effects reach you through a surprising number of channels. Knowing the source matters, because it tells you how to get an effect on purpose and how to avoid one you don’t want.
Potions
Potions are the main delivery system. A regular potion is drunk and affects only you. A splash potion is thrown and covers everything in the splash area, which is how you apply Harming to a mob or Healing to a teammate. A lingering potion leaves a cloud on the ground that reapplies the effect to anything standing in it. Tipped arrows carry whatever potion you craft them with, so a single hit can poison or slow a target from range.
Food and drink
Several foods carry effects. A golden apple grants Absorption and short Regeneration, and an enchanted golden apple piles on Fire Resistance and Resistance as well. Suspicious stew gives a different effect depending on the flower used to craft it. On the harmful side, raw chicken can give Hunger, a spider eye gives Poison, a poisonous potato can poison you, and rotten flesh almost always brings Hunger along with the food it restores. Pufferfish is the worst of the bunch, dishing out Poison, Hunger, and Nausea in one bite.
Beacons and conduits
A beacon projects a chosen effect across a wide area for as long as you stay in range, with the strength tied to how big you build the pyramid beneath it. The available options include Speed, Haste, Resistance, Jump Boost, Strength, and, on a full pyramid, Regeneration as a secondary power. A conduit built from prismarine and a heart of the sea grants Conduit Power underwater, which combines breathing, night vision, and faster mining below the surface.
Mobs and the environment
Plenty of mobs apply effects through their attacks. A cave spider and a witch deal Poison, an Elder Guardian inflicts Mining Fatigue to slow your assault on an ocean monument, a Shulker’s projectile gives Levitation, and a wither skeleton’s blade leaves the Wither effect. The Warden and a triggered sculk shrieker both cause Darkness. Swimming near a dolphin grants Dolphin’s Grace, and winning a raid leaves the whole party with Hero of the Village.
Commands
In creative or on a server with permissions, /effect give applies any effect at any level and duration, and /effect clear wipes them. This is the only way to reach a few effects, such as Health Boost and Saturation, that no potion produces.
Beneficial effects
Beneficial effects help the player. Here are the common ones and what they do.
| Effect | What it does | Common source |
|---|---|---|
| Speed | Faster walking and sprinting | Potion of Swiftness, beacon |
| Haste | Faster mining and attacking | Beacon |
| Strength | More melee damage | Potion of Strength, beacon |
| Jump Boost | Higher jumps, softer landings | Potion of Leaping |
| Regeneration | Heals health over time | Potion of Regeneration, golden apple |
| Resistance | Reduces incoming damage | Enchanted golden apple, beacon |
| Fire Resistance | Immunity to fire and lava | Potion of Fire Resistance |
| Water Breathing | Breathe underwater | Potion of Water Breathing |
| Night Vision | See in the dark | Potion of Night Vision |
| Invisibility | Hides your body from view | Potion of Invisibility |
| Absorption | Extra temporary hearts | Golden apple, totem of undying |
| Slow Falling | Fall slowly, no fall damage | Potion of Slow Falling |
| Conduit Power | Breathing, vision, and mining underwater | Conduit |
| Dolphin’s Grace | Faster swimming | Swimming near a dolphin |
| Hero of the Village | Cheaper villager trades | Winning a raid |
Harmful effects
Harmful effects work against you, and mobs use most of them. A few are worth understanding in detail because they behave in ways players don’t expect.
| Effect | What it does | Common source |
|---|---|---|
| Slowness | Slower movement | Potion of Slowness, mobs |
| Mining Fatigue | Much slower mining and attacking | Elder Guardian |
| Instant Damage | Immediate burst of harm | Potion of Harming |
| Weakness | Less melee damage | Potion of Weakness, witch |
| Poison | Drains health, but cannot kill | Cave spider, pufferfish, spider eye |
| Wither | Drains health and can kill you | Wither skeleton, the Wither boss |
| Hunger | Food bar drains faster | Rotten flesh, husk attacks |
| Nausea | Wobbly, distorted screen | Pufferfish, nether portal |
| Blindness | Vision shrinks to a small circle | Suspicious stew, certain mobs |
| Darkness | Vision pulses dark | Warden, sculk shrieker |
| Levitation | Floats you upward against your will | Shulker |
The difference between Poison and Wither catches a lot of players out. Poison turns your hearts a sickly green and chips away at your health, but it stops at half a heart and never finishes the job. Wither turns your hearts black and has no such mercy, so it can drop you to zero. If your hearts go dark, treat it as an emergency.
Neutral effects
A small set of effects are neither clearly good nor bad. Glowing draws a colored outline around an entity that shows through walls, which a player might use to track a target or a mob might inflict on you. Levitation can be a death sentence over a drop or a free ride upward, depending on where you are standing. Bad Omen sits in its own corner: it carries no direct harm, but it sets the stage for a raid on the next village you enter. The 1.21 update reworked this system around the Ominous Bottle and added Raid Omen and Trial Omen, which start tougher raids and ominous trial chambers respectively.
How to remove a status effect
The simplest fix is to wait. Every timed effect ends on its own once the timer runs out. When you can’t wait, you have a few tools.
Drinking a bucket of milk clears every effect at once, good and bad alike. That last part matters: milk strips your buffs too, so don’t drink it mid-fight while Strength and Resistance are running. A honey bottle is the surgical option, since it removes only Poison while leaving your other effects intact, which makes it the right call when a cave spider catches you mid-buff. Dying clears everything as well, though that is rarely the plan. In creative or with command access, /effect clear removes a specific effect or all of them.
Tips and common mistakes
Brew a stock of Fire Resistance before any trip to the Nether; it turns lava from instant death into a minor inconvenience. Keep milk in an ender chest for emergencies, but remember it nukes your good effects too. When fighting an Elder Guardian, expect Mining Fatigue and bring extra time, because your pickaxe will crawl. Against the Wither boss, watch for black hearts and back off to heal rather than trading blows. And when you craft tipped arrows, the effect duration is shorter than the matching potion, so plan for a quicker fade.
Java and Bedrock differences
The two editions handle effects slightly differently. Strength adds a flat amount of melee damage in Java but a percentage in Bedrock, so the same potion does not do the same thing across editions. Luck and Bad Luck mostly matter in Java, where loot tables read them. Outside of a few cases like these, the core list and behavior line up closely between the two versions, so most of what you learn carries over either way.
Frequently asked questions
Can a status effect kill you?
Most cannot. Poison stops at half a heart and Hunger only empties your food bar. Wither is the exception, since it ignores that floor and can take you to zero. Instant Damage can also kill if the hit is large enough.
How do I remove all effects at once?
Drink a bucket of milk. It clears every active effect instantly, both helpful and harmful, so use it when you want a clean slate rather than during a fight.
Does milk remove good effects too?
Yes. Milk does not pick and choose. If you only want to cure Poison and keep your buffs, drink a honey bottle instead.
What does the amplifier number mean in the effect command?
It sets the effect level, but it starts counting at 0. An amplifier of 0 gives level I, 1 gives level II, and so on. So Speed II needs an amplifier of 1.
Why are my hearts black?
Black hearts mean the Wither effect, usually from a wither skeleton or the Wither boss. Unlike Poison, it can kill you, so heal up or clear it fast.
Can mobs get status effects?
Yes. Splash potions, tipped arrows, and lingering clouds all work on mobs, which is how you poison a group of enemies or weaken a zombie villager before curing it.
Getting the most from effects
The players who handle tough content well are usually the ones who treat effects as gear, not luck. A stack of Fire Resistance, a few golden apples, and a bucket of milk in the right slot turn most disasters into close calls. Learn which mob hands out which effect, and you will see trouble coming before it lands.
