Nether & travel¶

Portal math¶

1 nether block = 8 overworld blocks. Build nether-side hub tunnels and the overworld shrinks by 8×.
To link portals deliberately: divide the overworld X/Z by 8, build the nether portal at those coordinates. Portals link to the nearest existing portal within range — misplaced portals cause "wrong exit" surprises.
A portal frame needs only 10 obsidian (corners can be anything) — a water bucket + lava lake casts a frame with zero diamond pickaxe.

Fire Resistance potions turn the nether from lethal to casual — brew with nether wart + magma cream.
Bring: flint & steel (ghasts blow out portals), building blocks for bridging, a slab/cobble roof against ghasts on highways.
Don't sleep — beds explode in the nether. (Respawn anchors work instead.)
Hoglins fear warped fungus; piglins are neutral if you wear any gold armor piece.

Ice + boat: packed/blue ice boats hit ~40–70 blocks/s — the standard nether-highway design is a 2-wide blue-ice lane with a slab roof.
Elytra + firework rockets is endgame travel; until then, nether hubs beat overworld roads.
