The 1.21 Update Changed Everything
If you're still mining diamonds at Y=12, you're playing the wrong version of Minecraft. The Caves & Cliffs update radically altered how the underground generates.
Mountains go higher, caves go deeper, and ores spawn in triangular distributions rather than flat uniform layers. Understanding these new mechanics is the difference between a frustrating grind and a chest full of netherite. Dive into our guides to get up to speed.
