Astralium
Astralium is a late-game progression mod that expands Minecraft’s End with a rare cosmic material, powerful equipment, specialised mining abilities and unique movement mechanics.
Venture beyond the central End island to discover Astralium Ore among the outer islands. Recover an Astralium Upgrade Template from an End Ship, gather the materials you need and upgrade your Netherite equipment into a complete set of Astralium armour, weapons and tools.
Astral Momentum
Astralium weapons reward accurate, consecutive attacks through the Astral Momentum system.
Build Momentum by landing charged strikes without allowing the chain to expire. As your Momentum level rises, your attacks become increasingly powerful, encouraging deliberate timing rather than constant clicking. The Astralium Axe also gains improved attack speed as its Momentum builds.
Shifting Excavation
Astralium tools include configurable multi-block mining abilities designed to make large projects faster while keeping each tool useful for its intended blocks.
Switch between excavation modes to change the shape and direction of the mining area. The system respects tool suitability, block hardness, protected block entities and normal server-side block-breaking rules.
Astralium Armour
Wearing the complete Astralium armour set unlocks several powerful abilities:
Perform a double jump while airborne. Become immune to ordinary fall damage. Cross the lowest reaches of supported dimensions using a configurable virtual void floor. Place blocks directly onto the invisible floor to build above the void. Protect dropped Astralium equipment from being lost beneath the floor.
These abilities are designed especially for exploring and building in the End, where a single mistake would normally send valuable equipment into the void.
Progression
Astralium is intended to extend Minecraft’s late-game progression rather than replace it.
Reach and explore the outer End islands. Locate Astralium Ore. Search an End Ship for an Astralium Upgrade Template. Process the new material and upgrade your Netherite equipment. Master Momentum, excavation modes and the full armour set’s cosmic abilities. Configuration
Server owners can customise major parts of the mod, including:
Momentum duration and maximum level. Excavation dimensions and behaviour. Virtual-floor dimensions and height. Reconnect recovery distance. Dropped-item floor protection. Visual and sound effects.
Relevant server settings are synchronised with connected players for consistent multiplayer behaviour.
