You’ve finally done it. You stood toe-to-toe with the White Wraith, dodged the red lightning, and carved that magnificent bastard. But then you check your rewards. No Arkveld Calloushell. You run it again. Still nothing. Honestly, it’s enough to make any hunter want to throw their controller into the Scarlet Forest.
The Arkveld Calloushell is easily one of the most frustrating materials to farm in Monster Hunter Wilds. It’s not just rare; it’s mechanically tied to a part of the fight that most people overlook because they’re too busy trying not to get deleted by a dragon-element nuke.

If you’re struggling to upgrade that Rarity 8 weapon or finish your Guardian set, you aren't alone. This isn't just bad RNG. You’re probably fighting Arkveld wrong.
What is the Arkveld Calloushell?
Let’s get the basics out of the way. Arkveld is the flagship wyvern of Monster Hunter Wilds, known for those bizarre, chain-like appendages that extend from its wings. These aren't just for show. They act as "jumper cables" for elemental energy.
The Calloushell is a specific plating that protects the base of these chains. In-game lore suggests these parts are incredibly hardened because they constantly withstand the heat and friction of the chains retracting.
You need them for almost every high-end piece of Arkveld gear. Specifically, the Guardian Arkveld Mail $\alpha$ and the high-rank weapon upgrades require multiple shells. But here is the kicker: you cannot get these from carves.
The Breaking Point: How to Actually Get the Drop
Most hunters focus on the head or the tail. It makes sense. Head breaks yield gems, and tail severs are classic Monster Hunter. But if you want a Calloushell, you have to break the Chainblades on its wings.
This is harder than it sounds.
Arkveld is acrobatic. It moves like a Tigrex on espresso. Those wings are constantly in motion, and their hitboxes are surprisingly thin. If you use a Great Sword or a Hammer, you're going to have a rough time hitting them consistently without a plan.
- The Window: When Arkveld performs its "Ground Scrape"—where it buries a wing and pulls back—the wing stays stationary for about three seconds. That is your primary window.
- The Trap Strategy: Use Pitfall Traps. When Arkveld is in a Pitfall, its wings are flared out and accessible at ground level. This is the absolute best time to dump damage into the chains.
- Partbreaker is Mandatory: Don't even bother farming these without at least Level 2 Partbreaker. The durability threshold for the chains is significantly higher than the head.
I’ve seen dozens of lobbies fail to get a single break because everyone is chasing the tail. If you see a teammate focusing the wings, help them. You can break both the left and right chains for two chances at the shell per run.
Why Your Elements Might Be Failing You
Arkveld is a weird one. While the Hunter’s Notes say it’s weakest to Dragon, that doesn't apply to the chains.
The chainblades themselves are actually immune to elemental damage when they aren't empowered. When Arkveld enters its "enhanced state"—the part where it glows and starts siphoning energy from the environment—the wings become vulnerable to elemental overload.
If you hit the wings with enough elemental damage during this state, you trigger an energy leak. This not only deals massive damage but usually results in a long topple. This is the "secret" to breaking the wings effectively. You have to wait for it to get angry, then punish the very organs it uses to power up.
Combat Nuances: Surviving the White Wraith
You can't farm what you can't kill. Arkveld is designed to punish players who stay at mid-range.
Its tendril strikes have massive reach. If you stand ten feet away, you’re in the "danger zone" where the chains reach their maximum whip velocity. Paradoxically, the safest place to be is right under its chin.
- The Head Tilt: Watch for a slight tilt of the head before the double claw slam. If you see that, dodge diagonally toward the monster, not away.
- The Nuke: When it roars and the ground starts glowing red, it’s about to chain three explosions. Most people panic and run. If you’re behind it, you can actually stay there and keep attacking. The hitboxes only bloom in a frontal arc.
- Seikret Tech: Use your mount! If you get hit by a chain and knocked back, immediately call your Seikret. The mounting animation has a few frames of super armor that can save you from a follow-up strike.
Managing the Dragonblight
Getting hit by Arkveld’s empowered attacks usually results in Dragonblight. This is a death sentence for elemental builds because it nullifies your weapon's element.
Since you need that elemental damage to overload the wings and get your Calloushell, you need to clear it fast. Keep Nulberries on your radial menu. Better yet, if you can fit it into your build, get Dragon Resistance up to 20. It makes you immune to the blight entirely, which lets you stay aggressive when the monster is most vulnerable.
Actionable Next Steps for Efficient Farming
If you want to stop the endless grind and actually finish your set, follow this specific checklist for your next hunt:
- Switch to a Precision Weapon: If you're a Hammer main, consider picking up a Bow or Light Crossbow specifically for this farm. The ability to target the chains while Arkveld is moving is a game-changer.
- Equip Partbreaker: Slot in those Destroyer Jewels. You need to break the chains before the monster's HP hits zero. In many high-rank groups, Arkveld dies way too fast for the wings to break naturally.
- Focus the Wings Early: Don't wait for the end of the fight. Start every engagement by tenderizing the wing joints in Focus Mode.
- Check the Field Guide: Always double-check your drop rates in the Environment Overview. If you're in a locale where Arkveld has absorbed a specific element (like Thunder in the Windward Plains), its wing behavior changes slightly.
Breaking the Arkveld Calloushell loop is about shifting from "kill it fast" to "dismantle it carefully." Focus on those chains, ignore the tail for a few runs, and you'll have your materials in no time.
