No hostile mobs can spawn naturally, except for shulkers, hoglins, zoglins[Bedrock Edition only], piglin brutes[Bedrock Edition only], and the ender dragon. No mobs can deal damage to player in peaceful. No spiders, cave spiders, zombified piglins or endermen – neutral rather than hostile mobs – can spawn naturally. When any of these mobs attempt to spawn (whether naturally, through mob spawners, spawn eggs, or commands), they are removed from the game instantaneously. When the difficulty is switched from any other setting to Peaceful, all mobs that are not allowed to spawn on Peaceful are removed from the world. Players regain health rapidly over time. Despite this, it is still possible to die if damage is received quickly enough. TNT deals no direct damage to the player, but it does give knockback still, meaning a player can be killed by it if it launches them too far upward. The hunger bar never depletes; in Java Edition, players therefore cannot eat anything except golden apples, chorus fruits, and milk buckets, unless the player switched to Peaceful when their hunger bar was below the maximum. Players can eat normally in Bedrock Edition. Additionally, if the hunger bar is below the maximum, it regenerates quickly.
End portals cannot be activated by the player in Peaceful difficulty, because it is impossible to acquire the twelve eyes of ender necessary to activate an end portal. However, it is possible for an end portal to be activated by naturally generating with an eye of ender already embedded within all 12 end portal frames. For any given end portal, there is only a 1 in a trillion chance of this happening. However, because of the huge number of possible seeds, over 8 million seeds in Java Edition are known to generate such end portals. 
Also, not all advancements / achievements can be completed in Peaceful difficulty.
Hostile mobs spawn, but they deal less damage than on Normal difficulty. The hunger bar can deplete, damaging the player until they are left with 10 if it drains completely. Cave spiders and bees cannot poison players on Easy difficulty, and the wither does not cause the Wither effect, although wither skeletons do. Lightning sets only the struck block on fire, not surrounding blocks. Zombies do not break down doors, and do not turn villagers into zombie villagers. Zombies and skeletons don't wear full sets of armor. Hostile mobs like zombies, skeletons, spiders, husks and strays deal about 1 or 2 damage.
Hostile mobs spawn and deal standard damage, about 2 or 3. The hunger bar can deplete, damaging the player until they are left with with 1 if it drains completely. Zombies do not break down doors, but villagers killed by zombies have a 50% chance of turning into zombie villagers. Zombies and skeletons rarely wear sets of enchanted armor. Vindicators can break doors.
Hostile mobs deal more damage than on Normal difficulty. The hunger bar can deplete, damaging the player until they die if it drains completely. Zombies can break through wooden doors and can spawn reinforcements when attacked. Spiders can spawn with a beneficial status effect (speed, strength, regeneration & invisibility), with these effects having a nearly infinite duration in Java Edition. Villagers killed by zombies always turn into zombie villagers. Pillagers spawn near the player, with their attacks dealing 4 damage. In Bedrock Edition, if the world type is infinite, they deal 5 damage.
In Java edition, at the world creation screen, selecting Hardcore from among the game mode options causes the player to spawn in Hard difficulty, does not allow it to be changed, and allows the player only one life. In a single player world, a player who dies can choose to respawn in Spectator mode or return to the title screen. In multiplayer, upon death, the player's game mode is automatically set to Spectator mode.
The only way to change the difficulty of Hardcore is to use the Open to LAN feature in the pause menu to enable commands, or to use an .NBT editor on the world's .NBT file.
This difficulty is currently not available in Realms.
The moon does not actually have to be in the sky for this effect to take place, since the moon exists in daytime and across dimensions.
Regional difficulty or local difficulty is a value between 0.00 and 6.75 that the game calculates by considering not just the world difficulty setting, but also the inhabited time of a chunk, the total daytime in the world, and the phase of the moon. This value is shown on the debug screen as the first value listed after the heading "Local Difficulty". This value determines several aspects of the difficulty of gameplay (see below).
The inhabited time of a chunk increases for each tick a player spends with the chunk loaded. This is a cumulative measure of time—if 50 players spend a single hour in a chunk, it counts the same as if one player spent 50 hours there. The effect of inhabited time on regional difficulty is capped at 50 hours.
The total daytime in the world is the value from
/time query daytime added to the "Day" on the F3 debug screen converted to ticks, i.e.
daytime + (dayNumber * 24,000). This is not the same as the actual playtime in the world (the value from
/time query gametime). It affects the regional difficulty after the first 3 in-game days, and has no additional effect after 63 in-game days.
In pseudocode, the calculation of regional difficulty is:
# DaytimeFactor, ChunkFactor, and RegionalDifficulty are floating-point variables # MoonPhase is as in the table above. if (difficulty is Peaceful) return 0 if (TotalDaytime > 63 in-game days) DaytimeFactor = 0.25 else if (TotalDaytime < 3 in-game days) DaytimeFactor = 0 else DaytimeFactor = (TotalDaytimeInTicks − 72,000) / 5,760,000 if (ChunkInhabitedTime > 50 hours) ChunkFactor = 1 else ChunkFactor = ChunkInhabitedTimeInTicks / 3,600,000 if (difficulty is Normal or Easy) multiply ChunkFactor by 0.75 if (MoonPhase ÷ 4 > DaytimeFactor) add DaytimeFactor to ChunkFactor else add (MoonPhase ÷ 4) to ChunkFactor if (difficulty is Easy) multiply ChunkFactor by 0.5 RegionalDifficulty = 0.75 + DaytimeFactor + ChunkFactor if (difficulty is Normal) multiply RegionalDifficulty by 2 if (difficulty is Hard) multiply RegionalDifficulty by 3 return RegionalDifficulty
The raw regional difficulty therefore is always 0.0 on Peaceful and ranges from 0.75 to 1.5 on Easy, 1.5 to 4.0 on Normal, and 2.25 to 6.75 on Hard.
Clamped regional difficulty
The clamped regional difficulty is a value between 0.00 and 1.00 based on regional difficulty. This value is shown on the debug screen as the second value listed after the heading "Local Difficulty". This is yet another value that affects the difficulty of gameplay (see below).
The regional difficulty value is clamped as follows:
if (RegionalDifficulty < 2.0) value = 0.0; else if (RegionalDifficulty > 4.0) value = 1.0; else value = (RegionalDifficulty − 2.0) / 2.0;
Thus, on Easy, where regional difficulty is never higher than 1.5, the clamped value is always zero.
On Normal, the effects reach the maximum after 63 in-game days (1512000 game ticks) in a fully-inhabited chunk on a full moon; and on Hard after 63 in-game days the effects reach the maximum in chunks inhabited 4 1⁄6 hours during a full moon and remain at maximum in chunks inhabited over 16 2⁄3 hours.
- This applies only to mobs attacking the player. Mobs attacking other mobs always deal the 'Normal' damage listed, regardless of difficulty.
- Values for the creeper and ghast assume the player is directly adjacent to the explosion.
- The damage of slimes and magma cubes depends on their size. Tiny-sized slimes, while hostile, are unable to do damage directly.
- Mobs deal no damage on peaceful, apart from wolves[BE only] and llamas.

|Java Edition Classic|
|June 14, 2009||Notch discussed how his vision for Survival mode would incorporate the concept of difficulty: "When generating a new level or loading a creative mode level, you also select a difficulty. Difficulty levels will probably vary from 'challenging' to 'impossible', since I want the game to be difficult. If it's not fun to always be challenged, I'll add easier difficulties."|
|Java Edition Indev|
|0.31||20100205||Added the option to change difficulty to Peaceful, Easy, Normal, or Hard.|
|Java Edition Alpha|
|October 22, 2010||Notch tweets stating that he is "changing 'difficulty' to 'realism'". Lowest setting = Creative. Highest setting = starve". This was never implemented; however, a "Hardcore" mode was added along with a Creative gamemode.|
|1.0.0||Beta 1.9 Prerelease 2||Hardcore mode added.|
|1.6.1||13w16a||Regional difficulty added.|
|1.8||14w02a||Difficulty is now saved per-world, instead of globally; difficulty can no longer be changed from the title screen|
|Difficulty defaults to Normal instead of Easy|
|Difficulty can now be locked|
|1.16||20w17a||Difficulty can now be chosen on world creation.|
|Pocket Edition Alpha|
|v0.4.0||Added Peaceful difficulty.|
|v0.12.1||Added Easy and Hard difficulties.|
- An eye of ender requires a blaze rod to craft; but a blaze rod can be obtained only as a drop from a blaze, which is a hostile mob that cannot spawn in Peaceful.
- Since each end portal frame has a 1⁄10 chance of being filled, there is a (1⁄10)12 = 1⁄1 trillion chance of all 12 end portal frames being filled.
