< N/A	> The Dominion Update (2024)

The Fracture Update is the name for a major update that was released for Mobcraft on June 17, 2023. The update introduced a large-scale overhaul of world generation, underground terrain, environmental mechanics, and mob behavior, fundamentally changing how worlds are formed and explored. The Fracture Update marked a turning point in Mobcraft development, shifting the game away from static terrain generation toward a more dynamic and evolving world system.

The update centers on the introduction of fractured terrain, unstable regions of the world affected by geological stress. These fractures can alter surface landscapes, cave systems, structures, and mob spawning behavior over time. Unlike previous updates, which primarily expanded existing features, the Fracture Update redefined core world mechanics, making terrain instability, environmental risk, and adaptive exploration central to gameplay.

The official name for the update, the Fracture Update, was revealed during a developer showcase earlier in 2023, where it was described as the foundation for future world-scale systems and long-term progression mechanics.

Release

The Fracture Update was released worldwide on June 17, 2023. The update applied to both new and existing worlds, though fractured terrain primarily generated in unexplored areas to preserve older builds. Existing worlds could still experience minor fracture events through environmental triggers.

Blocks

Fractured Stone

• Generates naturally in fractured zones.
• Can collapse when unsupported.
• Emits subtle particle effects when instability is nearby.

Reinforced Fractured Stone

• Crafted using Fractured Stone and iron.
• Immune to collapse mechanics.
• Used for safe construction in unstable regions.

Cracked Bedrock

• Rare block found deep underground in fractured areas.
• Can be temporarily broken using specialized tools.
• Slowly regenerates over time.

Fault Crystal Block

• Generates near fracture cores.
• Emits light and periodic pulses.
• Used in advanced crafting and structures.

Seismic Gravel

• Falls faster than normal gravel.
• Can trigger chain collapses.

Collapsed Rubble

• Forms after terrain collapse events.
• Can be mined faster than stone.
• Occasionally drops rare fragments.

Stabilizer Pylon

• Prevents collapse in a limited radius.
• Requires energy items to remain active.

Fault Glass

• Decorative translucent block.
• Emits faint light when placed near fractures.

Items

Effects

Instability

• Causes random knockback, mining disruption, and tremors.
• Increases mob aggression.

Stabilized

• Prevents collapse effects.
• Reduces hostile mob spawn rates.

Seismic Fatigue

• Slows movement and mining after prolonged exposure to fractured zones.

Enchantments

• Reinforcement – Reduces block collapse chance.
• Anchoring – Prevents knockback from seismic effects.
• Seismic Touch – Reveals unstable blocks when mining.
• Fracture Bane – Increases damage to fracture-related mobs.

Mobs

Shatterling

• Hostile mob found in fractured zones.
• Can trigger minor collapses when attacking.

Fault Stalker

• Neutral mob that becomes hostile under instability effects.
• Drops Fault Fragments.

Rift Crawler

• Rare hostile mob spawning near fracture cores.
• Capable of burrowing through unstable blocks.

Seismic Golem

• Large hostile mob formed from fractured stone.
• Highly resistant to normal weapons.

Echo Wisp

• Passive mob that appears during seismic events.
• Emits warning sounds before collapses.

Generated structures

Fracture Core

• Central structure of fractured zones.
• Source of instability effects.
• Guarded by powerful mobs.

Collapsed Caverns

• Underground cave systems formed by terrain failure.
• Contain rare resources and hazards.

Fault Ruins

• Ancient structures embedded in fractured terrain.
• Contain lore items and loot.

Seismic Spires

• Tall crystal formations above fracture cores.
• Visible from long distances.

Biomes

Fractured Plains

• Open biome with surface cracks and sinkholes.

Shattered Depths

• Deep underground biome with unstable ceilings and rare ores.

Rift Expanse

• High-risk biome surrounding fracture cores.

Seismic Badlands

• Dry biome with constant tremors and reduced stability.

World mechanics

• Terrain can dynamically collapse under certain conditions.
• Seismic events can reshape caves and surface terrain.
• Mob spawning increases near fracture cores.
• Fractures can expand slowly over time if left untreated.
• Environmental audio cues warn players of instability.

Changes

• Complete overhaul of underground generation.
• Improved cave depth and verticality.
• Updated mob pathfinding for unstable terrain.
• Adjusted mining speeds based on stability.
• New ambient sound system for fractured zones.
• Improved lighting behavior in collapsing areas.

Further revisions

• Version 1.6.1 fixed unintended large-scale collapses and improved stability.
• Version 1.6.2 improved performance in high-fracture-density worlds.
• Version 1.6.3 adjusted mob spawn balance and fracture spread rates.

Trivia

• The Fracture Update was the first Mobcraft update to introduce dynamic world evolution.
• Early internal builds allowed entire chunks to collapse, which was later limited.
• Fault Crystals were originally planned to explode during seismic events.
