Crafting Wooden, Stone, Copper, Iron, Golden, and Diamond Greathammers
Greathammers exist for six material tiers in Jaam's Weaponry, and every one of them is built from the same recipe shape: four heavy pieces, two double pieces, and a 
Long Stick. The material changes, but the layout does not. Once you understand the pattern for one tier, you understand all six.
The Shared Recipe Pattern
Each greathammer is a shaped craft. The head of the weapon is formed by four heavy components arranged together, with two double components filling out the rest of the head. A single Long Stick serves as the handle. Because the recipe is shaped, the positions of these ingredients matter — the heavy pieces and double pieces form the hammer head, and the Long Stick extends from it as the shaft.
The six tiers are:
Wooden Greathammer
Stone Greathammer
Copper Greathammer
Iron Greathammer
Golden Greathammer
Diamond Greathammer
Wooden Greathammer
The Wooden Greathammer is the entry point. Its head uses four 
Heavy Compressed Wood and two 
Double Compressed Wood, plus one Long Stick. This is the tier to build first if you are working your way up from basic materials.
Stone Greathammer
The Stone Greathammer follows the same layout with stone components: four 
Heavy Compressed Stone, two 
Double Compressed Stone, and one Long Stick. It mirrors the wooden version exactly, swapping wood for stone.
Copper Greathammer
For the Copper Greathammer, the components are metal rather than block-based. You need four 
Heavy Copper Ingot, two 
Double Copper Ingot, and one Long Stick. Note that copper uses ingots here, not compressed blocks.
Iron Greathammer
The Iron Greathammer uses four 
Heavy Iron Ingot, two 
Double Iron Ingot, and one Long Stick. As with copper, the iron tier is built from ingot-based components.
Golden Greathammer
The Golden Greathammer requires four 
Heavy Gold Ingot, two 
Double Gold Ingot, and one Long Stick. The gold tier keeps the same ingot-based structure as copper and iron.
Diamond Greathammer
The Diamond Greathammer is built from four 
Heavy Diamond, two 
Double Diamond, and one Long Stick. Unlike the metal tiers, diamond uses the gem directly in its heavy and double forms rather than an ingot.
What Stays the Same Across All Six
Every greathammer in this set shares three things:
- A count of four heavy components.
- A count of two double components.
- Exactly one Long Stick.
Only the material names change. Wood and stone use compressed block forms, copper, iron, and gold use ingot forms, and diamond uses the gem itself. If you can craft one tier, you can craft them all — just gather the right heavy and double components for the material you want and arrange them in the same shaped pattern with a Long Stick.
Planning Your Crafts
Because the recipe shape never changes, the real work is producing the components. Each greathammer needs six upgraded pieces (four heavy plus two double) before you can assemble it. Decide which tier you are targeting, prepare those six components, and keep a Long Stick on hand for the handle. From there, the craft itself is identical no matter which of the six greathammers you are making.
