In order to make the Ravage Hammer, you need to morph the Hammer recipe with Creaminea.

These are the requirements you need to create the Ravage Hammer:

1. Obtain a Degenesis Stone: You will need a Degenesis Stone to create the Creaminea.
2. Collect Mordenite: The Creaminea recipe also requires Mordenite as a core ingredient.
3. Gather Pentanite: The Hammer recipe will require Pentanite.

Obtaining the Ingredients

You will need to collect a Degenesis Stone, Mordenite, and Pentanite. 

You can find the Degenesis Stone in the Nemed region. Both the Mordenite and the Pentanite are available in the Cleria region.

Degenesis Stone

The Degenesis Stone is extremely easy to obtain. Simply use a Hammer with Gathering Rank 2 on the boulders around the Nemed region.

Mordenite

Mordenite is also extremely easy to obtain. Use an axe with Gathering Rank 2 or better on the boulders near the Cleria Region Atelier.

Pentanite

For the Pentanite, use a Hammer on the large green crystals you find around the Cleria region.

Synthesizing the Ravage Hammer

Once you have all ingredients, return to the Atelier.

First, synthesize the Creaminea, which is the second morph in the Ingot recipe tree:

• Ingot into Startium (requires Arknite).
• Startium into Creaminea (requires a Degensis Stone).

After that, select the Hammer recipe. You must achieve at least 100 Quality in order to complete the recipe morph, so keep an eye on your ingredients’ Quality.

Start from the Effect 2 loop, and insert an Amatite Ore.

Add Eiche to the Effect 1 loop. This loop has an Ice Element Level 3 requirement.

Proceed to the loop right above this one.

Use a Lumber-category ingredient in the Traits loop, which requires Lightning Element Level 2.

Insert an Ore-category ingredient in the Quality loop, which has a Lightning Element Level 3 requirement.

You must meet the 100 Quality requirement in order to proceed. If your recipe isn’t there yet, just keep leveling up this Quality loop.

Add Pentanite to the second Effect 1 loop, which also has a Lightning Element Level 3 requirement.

Add Eiche to the third Effect 1 loop.

Add Creaminea to the Recipe loop, which has an Ice Element Level 3 requirement.

You can synthesize the recipe right away, and then use the Item Rebuild option to add all effects later.

In order to max out all the Ravage Hammer loops, you will need the following ingredients:

• Creaminea (Wind Element Level 3 loop).
• A second Creaminea ingot (Ice Element Level 4 loop).
• A third Creaminea ingot (Ice Element Level 5 loop).
• A fourth Creaminea ingot (Wind Element Level 6 loop).
• An Ingot-category ingredient (Fire Element Level 3 loop).
• A second Ingot-category ingredient (Lightning Element Level 3 loop).
• A third Ingot-category ingredient (Lightning Element Level 4 loop).
• A fourth Ingot-category ingredient (Fire Element Level 6 loop).
• A Lumber-category ingredient (Lightning Element Level 2 loop).
• A second Lumber-category ingredient (Lightning Element Level 3 loop).
• Another two Lumber-category ingredients (Lightning Element Level 5 loops).
• A fifth Lumber-category ingredient (Ice Element Level 5 loop).
• A Hammer (Fire Element Level 3 loop).
• Another Hammer  (Fire Element Level 6 loop).

The Ravage Hammer must have at least 300 Quality to unlock all loops.

Once you finish maxing out all loops, the Ravage Hammer will have these effects:

• Masterful Crushing (Gathering Rank 3).
• Gathering Up XL.
• Add (Gases).
• Add (General Goods).
