BLAST ALLOY
A protective building block for Fabric · Minecraft Java Edition 1.21.11
OVERVIEW
Blast Alloy is built around a simple idea: a wall should protect more than itself. Its custom alloy block has exceptional explosion resistance, and the shielding system adds protection checks for explosions and selected threats that would otherwise act through barriers.
Use the alloy to construct reinforced walls, shelters, protective chambers and enclosed structures. The focus is on separating the inside from the outside, not merely creating an indestructible-looking block.
THE BLOCK
• A dedicated Blast Alloy building block with its own name, appearance and animated texture.
• High explosion resistance for the alloy block itself.
• Additional shielding logic for effects crossing an alloy barrier.
• Integration with Sky Armor Trim Museum as an optional platform-foundation material.
HOW TO OBTAIN IT
In Creative Mode, find Blast Alloy in the Building Blocks category.
You can also use the following command:
/give @s blastalloy:blast_alloy
There is no survival crafting recipe in this release.
HOW TO BUILD WITH IT
Place Blast Alloy like any other building block. For a protected chamber, form continuous walls and include a Blast Alloy roof and floor. Close openings where you want separation from external threats.
The shielding system checks whether alloy blocks stand between an effect's source and its destination. This lets it address effects traveling from outside to inside and from inside to outside. An open doorway or missing section is not a protected barrier.
PROTECTION FEATURES
• Protection also includes potions and various negative effects that act directly on the body (not sure whether attacks cast from a distance can be blocked 🤣).
• Explosions — high block blast resistance, together with barrier checks for explosion damage, block destruction and related cross-wall effects.
• Enderman teleportation — checks intended to prevent an Enderman from teleporting through an intervening alloy wall.
• Warden — dedicated handling for vibration-based detection and Sonic Boom attacks across alloy barriers.
• Guardian and Elder Guardian — dedicated handling for their ranged beam attacks across barriers.
• TNT Chaos family — compatibility handling for TNT Explosion Arsenal, Missile & Grenade Expansion and Nuclear Flame-Gust Missile, including selected secondary explosion paths.
• Other sourced attacks — barrier checks for certain damage or effects whose source can be identified on the opposite side of the wall.
BLAST ALLOY × SKY ARMOR TRIM MUSEUM
The Sky Armor Trim Museum can use Blast Alloy blocks in its exhibition-platform foundation. Install both mods before the museum is first generated to enable that foundation combination. The museum can also run separately without Blast Alloy.
COMPATIBILITY
• Minecraft Java Edition 1.21.11
• Fabric Loader 0.19.3 or later compatible version
• Fabric API
• Java 21 or later
Blast Alloy is a standalone mod. Sky Armor Trim Museum is optional, not required.
