Key Points
- The “Decipher the Records Analyzed by the Witches” objective requires crafting Abyssal Fusion at Kilnden Workshop in Hernand.
- Abyssal Fusion needs four materials: Aeserion’s Scale, Golden Star’s Component, Power Core, and Small Kuku A.T.A.G.
- Each material comes from different activities, including boss rewards, exploration, enemy drops, and crafting blueprints.
The Wings of Iron quest in Crimson Desert is one of the least descriptive ones, as it just tells you to “Decipher the records analyzed by the Witches.” However, it actually means for you to visit the Kilnden Workshop in Hernand and craft an Abyssal Fusion for yourself. If you are also stuck on this segment, read on below.
How to Complete Decipher the Records Analyzed by the Witches Quest in Crimson Desert

Once you make your way to the Kilnden Workshop in Hernand and talk with Grimnir, you will see that crafting Abyssal Fusion requires the four materials mentioned below:
- 1x Aeserion’s Scale
- 1x Golden Star’s Component
- 1x Power Core – Ore of Resipiscence
- 1x Small Kuku A.T.A.G.
Upon gathering these materials and crafting Abyssal Fusion, you will successfully complete the Decipher the records analyzed by the Witches quest.

But finding these materials is no easy task. Out of all these materials, you would already have Golden Star’s Component in your inventory, as it is obtained from the boss fight in Chapter 11 (the quest unlocks after Chapter 11).
How to get Aeserion’s Scale

To obtain the Aeserion’s Scale, you need to head over to the Serpent Shrine near Three Brothers Cliff in the Deleysia region, as shown in the image above. A large serpent will be revolving in this area with NPCs attacking it.
You need to travel to the location marked with the red circle and use Axiom Force to pick up the Aeserion’s Scales dropped by the large snake. Do remember to seal these scales in a Kuku Pot.
How to obtain the Power Core

Next, to obtain the Power Core, you can explore the area near Willow River or Lake Kharonso, Scholastone. These areas have a high density of Runewalkers, Stone Worms, and other Stone Golem Abyss Creatures, which drop Power Core at random. I personally got a Power Core by defeating a Sand Worm near Willow River.
How to obtain the small Kuku A.T.A.G

Finally, to get a Small Kuku A.T.A.G., you just need to head over to Zargan Tankworks in Gorthak, as shown in the image above. Here you will meet Marek, who will give you the Small Kuku A.T.A.G. blueprint.
It requires 5x Cogwheels, 5x Small Battery, 1x Abyss Cell, and 1x Kuku Pot to build. All these items are commonly found and would not require you to search a lot.

With all the materials in your inventory, head back to Kilnden Workshop in Hernand. First, craft the Small Kuku A.T.A.G. using the materials, and then craft Abyssal Fusion material to complete the quest.
