The Iron Eagle is one of the rarest companions you can add to your collection in Crimson Desert, and Pearl Abyss made sure it earns that reputation. Introduced in Patch 1.05.00, this mechanical bird sits dormant at Hawkstone Ruins in eastern Delesyia until you solve a time-locked gear puzzle, gather a specific resource, and place your Sotdae of Bond in exactly the right spot. No combat required, but plenty of preparation.
Where to find the Iron Eagle
The Iron Eagle perches on top of a large gear and metal sculpture at Hawkstone Ruins, located in eastern Delesyia, south of Marni's city. On your map, look just above the A in Delesyia. The ruins themselves have been in the game since launch, but the Iron Eagle event only became active with Patch 1.05.00. If you passed through here earlier, you may remember the mechanical structure without being able to interact with it.

Iron Eagle at Hawkstone Ruins
The bird is large enough to spot from a distance once it's active. After the puzzle triggers it, the Iron Eagle flies wide circles around the ruins, occasionally drifting toward the Sanctum of Oblation or Marni Mechworks before looping back.
The Iron Eagle is the biggest bird in the Hawkstone Ruins area, so tracking it in the air is straightforward once it's airborne.
How does the gear puzzle work?
Beneath the Iron Eagle's perch, you'll find a set of rotating gears next to a plaque. Examining the plaque reveals this riddle:
"Step beyond the edge of darkness and grasp the handle of dawn to awaken the slumbering steel. Offer the silver shards flowing through the Sotdae, and claim the Wings of Steel."
The mechanism functions as a clock. You need to arrive and interact with the gear gate during the dawn window, which sources place between 4:45 AM and 5:00 AM in-game time. At that point, the gears align, a hole opens in the center of the mechanism, and you can reach in to activate the Iron Eagle. No weapons, no Visione required. Just walk up and interact when the time is right.
This triggers a short cutscene showing the Iron Eagle coming to life and taking flight.
Arrive at the ruins slightly before 4:45 AM in-game time so you're already in position when the window opens. Missing it means waiting for the next in-game day.
How to farm Mercury for taming
Before heading to Hawkstone Ruins, you need Mercury, the only material the Iron Eagle will eat. You need at least 20 individual pieces to raise the bird's trust meter to 100. The trust gain is slow compared to other animals, so bring a full stack.
There are two reliable Mercury deposit locations:
- North of the Silver Wolf Mountains in Pailune, just above the W in "Wolf" on your map.
- North of Hexe Sanctuary in Demeniss, east of Deadfire Mountain. Be aware that this deposit may be inaccessible until you defeat the witch guarding the territory in Chapter 9. Approaching before then causes crows to swarm you, resulting in a blackout.
Mercury deposits appear as pools of silver liquid that deal damage if you stand in them. To harvest the material, equip your bow and imbue Charge Shot with the Frost element. The frozen chunk shatters, drains some of the liquid, and leaves collectable Mercury pieces on the ground.

Freezing Mercury with Frost bow shot
Do not shoot the Iron Eagle once it's airborne. Unlike the Phoenix, shooting the Iron Eagle counts as Assault and will break the taming sequence.
How to Tame Iron Eagle
Here is the full sequence once you have your Mercury and reach the ruins:
- Travel to Hawkstone Ruins in eastern Delesyia before dawn.
- Wait near the gear gate structure until 4:45 AM to 5:00 AM in-game time.
- Interact with the gear mechanism to trigger the cutscene and release the Iron Eagle.
- Place your Sotdae of Bond directly in the Iron Eagle's flight path near the statue. If it's not in the path, the bird will ignore it.
- Load the Sotdae with Mercury. Consider emptying any other food from the feeder first to avoid other birds eating your supply.
- Wait for the Iron Eagle to land and begin feeding. Avoid moving around too much during this phase.
- Allow the trust meter to reach 100, then select "Take In" to claim the Iron Eagle as your pet.
One alternative approach documented in community testing: a single Platinum Bar placed in the Sotdae will raise trust to 100 in one feeding, compared to 20 pieces of Mercury. Mercury reportedly gives 5 Trust per piece, meaning you need the full 20 to hit 100. Platinum can be more practical if you're already in Delesyia naturally, since it requires fewer trips.

How to get Platinum (if you prefer the faster route)
You need a Witch's help to craft Platinum. The recipe is available from two locations:
- A bookshelf at Scholastone Institute, accessible after obtaining the key during Chapter IV: The Price of Knowledge.
- A bookshelf on the west side of the Great Gate of Urdavah, near the Scholars.
The Platinum crafting recipe requires:
- Gold Bar x1
- Brimstone x4
- Mercury x3
- Holy Water x2
What if you've lost your Sotdae of Bond?
You get the Sotdae of Bond by completing the Trembling Woods quest line in Pororin Forest. If you've already used it and it's no longer in your inventory, head to Greymane Camp and speak to Cliff. The feeder should appear in the "Recover Items" section.
What does the Iron Eagle actually do as a pet?
Once claimed, the Iron Eagle functions like other companions in the game. It offers no combat bonuses or stat buffs, but it will gather materials scattered around the world or left on enemy corpses. You can rename it and equip it through your inventory under the "Pets" sub-tab.
The main draw is rarity and visual distinction. The Iron Eagle is a time-locked, item-gated mechanical bird with a unique activation sequence, making it one of the more distinctive pets available. For collectors and completionists, that's reason enough.
For more on the broader pet system, including how Trust works and what other animal companions are available, the Crimson Desert pets guide covering how to unlock animal companions covers the full picture. If birds are your focus specifically, the guide on how to tame birds in Crimson Desert walks through the Sotdae system, food preferences, and all 30+ tamable breeds.
Is the Iron Eagle worth the effort?
The short answer is yes, if you care about rare companions. The puzzle is clever, the resource farming takes some effort, and the time-lock adds a layer of planning that most pets don't require. Pearl Abyss designed this as a calm, ceremonial encounter rather than a combat challenge, which makes a refreshing change from the Phoenix taming process (which does involve shooting the bird down with Explosive Arrows, as covered in our guide to taming the Phoenix pet).
