Astralium
by HirenS
Astralium is a Forge late-game mod that extends the End dimension with rare cosmic ore, upgradeable equipment and combat and movement abilities.
What it does
Astralium is built around the outer End islands. Players venture past the central End island to find Astralium Ore among them, and recover an Astralium Upgrade Template from the End Ship. That template and gathered materials are used to upgrade Netherite equipment into Astralium gear, and once a full Astralium armour, weapon and tool set is assembled, the set's abilities become available.
The equipment combines momentum-based combat, multi-block excavation tools and armour abilities such as double jumping and void protection. Accurate consecutive hits feed the Astral Momentum system, where landing charged strikes builds a momentum level that makes later attacks stronger without letting the chain expire. The mod is intended to extend late-game progression rather than replace it.
Astralium requires Forge and runs on client and server, so the server and every player need it. Files are published for Forge 1.20.1, with version 1.2.3 as the latest file, under the MIT License; the mod is not open source. Operators can adjust the main systems of the mod through its configuration.
Key features
Momentum combat
Consecutive accurate attacks build a momentum level, and higher levels make attacks increasingly stronger.
Multi-block excavation
Configurable tools dig several blocks at once, with switchable modes that alter the shape and orientation of the dig area.
Armour abilities
A complete Astralium armour set grants double jumping in midair, immunity to ordinary fall damage and placement of blocks on a virtual void floor.
Protected equipment
Dropped Astralium equipment is kept safe when it falls beneath the virtual floor, so a single mistake in the void does not destroy it.

Use cases
Late-game exploration
Players exploring the outer End islands can reach distant areas and build above the void with the armour abilities.
Large mining projects
Multi-block excavation modes speed up digging on big builds while respecting tool suitability and block hardness.
Who it’s for: Players who have reached the End and want new equipment, cosmic materials and abilities for the late game. Server owners running Forge 1.20.1 can configure the mod for their players.
