Abyssal Forge Alloys Mod extends Tinkers’ Construct with content from Alex’s Caves. The mod introduces six endgame materials spread across underground biomes. Each resource requires unique steps to find, mine, or process. Custom tool traits let you link containers, copy material powers, or survive extreme fights.

Abyssal Forge Alloys Mod

Features:

  • Adds full Tinkers’ Construct tool building compatibility for underground biomes.
  • Introduces six endgame materials with unique harvesting requirements and custom traits.
  • Allows tools to teleport mined items straight into linked storage chests.
  • Lets weapons mark targets to hit them with extra damage on follow-up swings.
  • Prevents tool durability loss completely when hunger remains full or near full.
  • Gives custom modifiers that let tools copy abilities from other materials in the mod.

New Materials:

  • Byzantium Neodymium: Spawns in Magnetic Caves and links tools to chests to teleport mined blocks.
  • Tectellus: Generates in Primordial Caves and only drops while the Luxtructiosaurus boss is alive.
  • Element 122: Located in Toxic Caves and requires a nuclear explosion or Tremorzilla beam to break.
  • Aurichalcum: Smelted from Atlantean Ruins in the Abyssal Chasm to grant traits from two other materials.
  • Prosprum: Purified from Desolum with light to apply a secondary strike against marked targets.
  • Gumbronze: Created by blending Amethyst Bronze with Earthen Gum to stop durability loss at high hunger.
