Tools and armor

  • A full tool set — pickaxe, axe, shovel, hoe — plus a sword.
  • A four-piece armor set: helmet, chestplate, leggings, boots.
  • All gear is registered into the vanilla tool, armor, and enchantable tags, so it enchants and repairs like top-tier equipment.

The Aetherium Greatblade

The centrepiece weapon. On a successful hit it unleashes a rider effect tied to your chosen Aspect — fire, slowness, a speed burst, bonus magic damage, a heal, or wither. With no aspect set, it strikes as a heavy blade with no rider.
