Mechanics

Coordinates

Coordinates: X is east/west, Y is elevation, and Z is south/north. Save X and Z for travel; use Y for mining and vertical alignment.

Ore Distribution

Ore Distribution: Every ore has preferred elevation and exposure rules; choose the target ore first, then select Y level and mining method.

Enchanting Costs

Enchanting Costs: Bookshelves raise available enchantment levels; the displayed level is the requirement, while only 1–3 levels are consumed.

Anvil Prior Work Penalty

Anvil Prior Work Penalty: Each anvil operation raises future cost. Combine books in a balanced tree and apply the final book to fresh gear.

Villager Trading

Villager Trading: A villager profession comes from an accessible job-site block; trade once to lock its profession and offers.

Mob Spawning

Mob Spawning: Hostile spawning depends on dimension, biome, light, distance from players, valid blocks, and the mob cap.

Redstone Signal Strength

Redstone Signal Strength: Redstone power ranges from 0 to 15 and usually drops by one per dust block; repeaters refresh it to 15.

Nether Portal Linking

Nether Portal Linking: Nether horizontal coordinates correspond to Overworld X and Z divided by 8; Y is not scaled.

Chunk Loading

Chunk Loading: The game processes only loaded chunks around players and special loaders; farms stop or change behavior outside simulation distance.

Fall Damage

Fall Damage: Fall damage starts after a short safe distance; water, hay bales, slime, slow falling, and Feather Falling reduce or cancel it.

Explosion Resistance

Explosion Resistance: Blast resistance controls whether explosions destroy a block; distance, line of sight, and explosion source still matter.

Status Effects

Status Effects: Effects have duration and amplifier levels; milk clears most effects, while some effects change when upgraded or extended.

Raids and Bad Omen

Raids and Bad Omen: Drink an ominous bottle to gain Bad Omen; entering a village converts it to Raid Omen before a raid begins.

Trial Omen

Trial Omen: Approaching a Trial Spawner with Bad Omen converts it to Trial Omen and enables harder ominous encounters.

Durability and Repair

Durability and Repair: Durability decreases with use. Unbreaking reduces durability consumption; Mending converts collected XP into repairs.
