About this seed
Seed 934598 is referenced directly in Mojang bug report MC-307323 as the reproduction case for surface sulfur cave generation when world weirdness drops below about -1.25. Mojang marked related reports as "Works As Intended," meaning this bizarre generation is now a feature, not a bug.
Teleport to 0, 70, 0 after creating the world to stand on the surface sulfur biome. You'll see sulfur blocks, springs, and sulfur cubes spawning in the open — ideal for testing potions, builds, and mob farms using Chaos Cubed blocks.
This is the reference seed cited by creators including PhoenixSC when explaining how surface sulfur biomes work in 26.2.
