Forging Ferrum and Blood Coated Ingots in Macabre
Ferrum metallurgy and blood-coated forging provide the vital tier of metallic progression in Macabre. By combining extracted subterranean ores with biological coagulants, smiths can produce hardened gear that surpasses mundane metals.
Mining Ferrum Ore and Bleeding Stone
Subterranean exploration reveals two fundamental mineral resources embedded within the surrounding 
Hard Stone from Y level 320 down to Y level -64:
Ferrum Ore: Generates in veins containing nine blocks across biomes such as Rotting Field, Deathless Valley, Gloom Forest, and Teething Forest. Mining it drops 
Raw Ferrum.
Bleeding Stone: Known in mod data as blood clot ore, this mineral generates in veins of nine blocks across similar subterranean elevations. Breaking it yields 
Raw Blood Clot.
Gathering abundant quantities of both raw resources is essential for commencing alloy refinement.
Smelting Ferrum Ingots
Raw Ferrum can be processed into usable 
Ferrum Ingot through standard furnace smelting or chemical dissolution:
- Furnace Smelting: Smelting one Raw Ferrum in a furnace or blast furnace yields one Ferrum Ingot.
- Chemical Extraction: Combining one Raw Ferrum with one
Scorching Acid inside a crafting grid instantly dissolves outer slag to yield one Ferrum Ingot. - Compact Storage: Nine Ferrum Ingot items assemble into one
Block of Ferrum, which can be disassembled back into nine ingots. - Construction Hardware: Six Ferrum Ingot items craft twelve sturdy
Ferrum Bar blocks for grates and cages.
Ferrum Ingot items craft a full suite of reliable survival equipment, including 
Ferrum Sword, 
Ferrum Pickaxe, 
Ferrum Axe, 
Ferrum Shovel, 
Ferrum Hoe, 
Ferrum Spear, 
Ferrum Mace, 
Ferrum Dagger, and the four pieces of Ferrum armor: 
Ferrum Helmet, 
Ferrum Chestplate, 
Ferrum Leggings, and 
Ferrum Boots.
Blood-Coated Refinement
To transcend the baseline properties of Ferrum, metallurgists synthesize coagulated blood into an alloy coating:
- Synthesizing Blood Clot: Combine eight Raw Blood Clot items with one
Plasma in a crafting table to form one 
Blood Clot. - Coating Ferrum: Place four Blood Clot items around one Ferrum Ingot in a crafting table to forge two
Blood Coated Ferrum Ingot items. - Crystallization: Infuse four Blood Coated Ferrum Ingot items with one
Solid Acid on a crafting table to produce four 
Crystalized Blood Clot ingots. - Massive Storage: Nine Crystalized Blood Clot ingots assemble into one decorative block named
The Clot.
The Blood Clot Equipment Suite
Crystalized Blood Clot ingots allow players to forge specialized weapons and armor that boast enhanced resilience and combat statistics:
Blood Clot Sword: Two Crystalized Blood Clot ingots above one stick.
Blood Clot Pickaxe: Three Crystalized Blood Clot ingots across the top row above two sticks.
Blood Clot Axe: Three Crystalized Blood Clot ingots in the upper corner supported by two sticks.
Blood Clot Shovel, 
Blood Clot Hoe, 
Blood Clot Spear, 
Blood Clot Mace, and 
Blood Clot Dagger: Follow standard crafting patterns using Crystalized Blood Clot ingots and sticks.- Protective Armor: Craft
Blood Clot Helmet with five ingots, 
Blood Clot Chestplate with eight ingots, 
Blood Clot Leggings with seven ingots, and 
Blood Clot Boots with four ingots.
This coagulated tier serves as the mandatory prerequisite armor when preparing to assemble the 
Cursed Armor of Baal.
