Practical write-ups on commands, datapacks, building and server performance — each one paired with the tool that does the work.

The Wandering Trader: 97 offers, but it will only buy from you 12 times

91 of its 97 trades cost emeralds and just 6 earn them — and every one of those six is capped at 2 uses. It is the largest trade list in the game and almost entirely one-directional.

World generation changed twice since 1.20, at 1.21.2 and 1.21.4 — and not since

The four generator ranges, spelled out. Everything from 1.21.4 through 26.2 shares one generator, so a seed checked on any of them is correct on all of them.

/worldborder has ten forms, and only two of them animate

set and add take an optional time argument that shrinks the border gradually; the other eight are instant. Plus what Minecraft's four border defaults actually mean.

Why Minecraft says "Too Expensive!" — and the anvil order that avoids it

The prior-work penalty doubles every time you touch an anvil. Here is the rule behind it, and how to sequence combines so a full enchant set never hits the 40-level wall.

The /give command after data components: what replaced NBT tags

1.20.5 replaced item NBT with data components, and most /give snippets online are still written the old way. Here is the mapping from the tags you know to the components that work now.

Nether portals that link where you want them to — the 1:8 rule in practice

Portals do not pair by coordinates alone. Here is the search box the game actually checks, why your portal keeps connecting to the wrong one, and how to force a clean pair.

Torch spacing for spawn-proofing: the exact number, not a guess

Hostile mobs need block light 0. Torches emit light 14 and lose 1 per block. That gives a precise grid — and a different answer for floors, ceilings and open builds.

Best Y level for every ore after the world height change

Diamonds are not at Y=11 any more. Each ore now has a triangular distribution with its own peak, and a few have a second band. Here are the real numbers from worldgen.

Ominous Bottles and Bad Omen I–V: what each level actually changes

Bad Omen no longer starts raids on its own. Here is what the five Ominous Bottle levels do to trial chambers and raids, and the give command for each.

The gamerules worth changing — and the defaults people get wrong

There are over 40 gamerules and most guides list them without saying which matter. Here are the ones that change how a world plays, with their real default values.
