Commands & Data guides — page 2
Guides to Minecraft commands and the data behind them: /give components, scoreboards, loot tables, damage types, /fill limits and anvil costs.
Enchantment conflicts: only 21 of 43 conflict with anything, and six do most of it
26.3 ships 43 enchantments. 22 conflict with nothing at all, level 3 is the most common cap, and Curse of Vanishing applies to more items than any other enchantment.
Negative coordinates break chunk maths in two places, not one
Truncating division puts block −1 in chunk 0 instead of −1, and a plain % gives an in-chunk offset of −1 instead of 15. Both are off, and both look right until you go west of spawn.
Brewing covers 19 of 40 effects — and four potions are not named after what they do
21 status effects cannot be brewed. Swiftness gives Speed, Leaping gives Jump Boost, Healing gives Instant Health — and /give and /effect need the different names.
2,042 recipes and 883 tags: stonecutting is a sixth of them, and one tag lists 449 blocks
26.3 ships 22 recipe types, brewing among them now, and crafting is not as dominant as it feels. On the tag side, mineable/pickaxe alone lists 449 entries and no vanilla tag uses replace.
Six version options, four world generators — three of them are the same world
26.1, 26.2 and 26.3 all resolve to one generator in the seed map — though 26.3 added a biome it cannot draw yet. And 1.21.1 and 1.21.3 are different generators, which catches people mid-line.
Spawn eggs cover 88 of 161 entities — and exactly three creatures have none
73 entity types have no spawn egg, but 68 of those are boats, projectiles and display entities. Only Giant, Illusioner and Mannequin are creatures you cannot egg.
The extension does not tell you the schematic format — 31 of 33 .schematic files were something else's guess
Five formats, four different ways of packing blocks, and .schematic is shared by two of them. Sniffing the NBT root beats trusting the filename, with counted evidence.
Ominous trial spawners: the loot changes, the spawn counts mostly do not
26.3 ships 28 trial spawner configs as 14 normal/ominous pairs. Every ominous one names its own loot tables and every normal one falls back to the defaults — and 9 of the 14 pairs spawn exactly the same mobs.
Villager trades by tier: Expert has the most, Master has the fewest
291 villager trades across 13 professions in 26.3. Level 4 carries 93 of them and level 5 only 27 — and there are 2.5× more ways to spend emeralds than to earn them.
The Wandering Trader: 100 offers, but it will only buy from you 4 times
94 of its 100 trades cost emeralds and just 6 earn them — each capped at 2 uses, and a trader only ever offers 2 of the six. The largest trade list in the game, almost entirely one-directional.
