Mining Fatigue is an effect that reduces mining efficiency and attack speed, opposite to Haste.

Attack speed

The effect decreases attack speed by 10% per level. For the in-game default level III, attack speed decreases by 30%.

Mining speed

The mining speed is reduced to 0.3^level of the normal mining speed. However, due to a bug MC-279819, increasing the effect level from II to III reduces the mining speed by a factor of 0.03, not 0.3. Thus, for the in-game default level III, the speed is reduced to 0.0027× of normal speed, taking 370 times longer than usual to break a block with its proper tool.

in Java Edition, levels higher than 4 work like level 4 for the purposes of calculating mining speed. However, attack speed can still decrease, all the way to 0% at level 10.

While afflicted, a player can still craft and ride entities as usual, but cannot remove most vehicles due to how slowly the vehicle can be broken.

The affliction is cured by drinking milk, although milk does not prevent a subsequent affliction by an elder guardian, which can happen within a few seconds‌^{[Java Edition only]} or immediately.‌^{[Bedrock Edition only]} Axolotls can also remove this effect, if the player helps an axolotl kill a mob while an axolotl was battling that mob.

The only natural cause of Mining Fatigue is from affliction by an elder guardian, when player is close to it and the only natural effect level is III. Other levels can be achieved via commands.

In Java Edition, once per minute, elder guardians in the vicinity search for any player within 50 blocks to afflict with Mining Fatigue III. A player cannot defend from this attack. Concealment behind blocks, underground, or by a potion of Invisibility offers no defense.

In Bedrock Edition, elder guardians within range afflict Mining Fatigue III immediately. Drinking milk to remove the effect results in re-infliction immediately after drinking the milk.

• Withers and ender dragons are immune to Mining fatigue.
• All mobs are unaffected by Mining fatigue as they cannot mine blocks.

• The effect does not affect block breaking in Creative mode, or blocks that are broken instantly by default.
• Axolotls can remove a player's mining fatigue if the player assisted it killing a mob.
