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.

Abyssal gear (endgame)

The top tier, one step beyond Aetherium. Forged from Abyssal Ingots — smelted by combining an Abyssal Core (the Abyssal Sovereign's drop) with a Riftcore. The full line mirrors Aetherium — five tools, the Greatblade, and four armor pieces — but every stat is raised for the Umbral Depths endgame. The Greatblade keeps its aspect-rider effect.
