Description
🛡️ The Size Shifter Expansion
Enhance your Minecraft journey with two incredible size-altering armors! The Size Shifter Expansion introduces the powerful Giant Armor and the stealthy Shrink Armor sets, utilizing Minecraft's native attribute systems to change your physical scale and capabilities.
With the Giant Armor, you gain overwhelming offensive power and extreme reach, but you must navigate the world with a significantly larger hitbox. With the Shrink Armor, your strength is reduced, but your minuscule size lets you slip into narrow gaps, secret passages, and 0.5-block spaces.
⚒️ How it Works
This datapack is built for the endgame. You will need elite nether-tech and deep-dark materials to forge these reality-bending sets.
-
🔴 The Giant Armor: Combine Netherite Ingots with Respawn Anchors to forge pieces of immense scale.

-
🔵 The Shrink Armor: Combine Netherite Ingots with Sculk Catalysts to compress your physical matter.

-
📖 Quality of Life: All recipes are visible directly in your vanilla crafting table book, and you can track your growth and shrinkage with unique in-game advancements!
