Hunters will initially meet Yian Kut-Ku after they finish the main quest and reach Chapter 4-1. For the New Ecosystems quest, Alma will guide players to the Scarlet Forest, where the Wudwuds will be talking about the existence of these Bird Wyverns. From there, players must get a good spot to spot them.

Yian Kut-Ku in Monster Hunter Wilds normally patrols the Scarlet Forest and Cliffs areas. But these monsters do not always go alone. If you're not so lucky, you may encounter a group of Yian Kut-Kus instead of a solo target. In these situations, Dung Pods come in handy to disperse them and not get swamped.

Yian Kut-Ku's weaknesses

As a Fire-type monster, Yian Kut-Ku naturally has a strong affinity for heat-based attacks. However, this also makes it highly vulnerable to Water. If Water weapons are unavailable, Ice and Thunder are secondary options, though less effective.

Yian Kut-Ku weak points

Additionally, Severing damage to the tail is highly effective. Avoid attacking the legs, as they have the highest resistance.

Best weapons to use

Since Yian Kut-Ku in Monster Hunter Wilds struggles against Water, any weapon imbued with Water-elemental attacks will be your best bet.

Hunt strategy

Yian Kut-Ku in Monster Hunter Wilds attacks in an expected manner but can suddenly change from defense to offense, which can make it difficult to catch. Since it tends to travel in groups, isolating your target with Dung Pods is important before attacking. When close, it uses a Pecking Frenzy, rapidly striking in succession — dodging backward or sideways is the best way to avoid getting caught in this sequence.

Its Fireball Spit uses Fireblight on contact, so constant motion is the best way to keep from getting hit. If you mind its tail too much, it will strike back with a Tail Sweep. There's a distinct wind-up animation for this attack — backing up will prevent the blow. One of its more threatening attacks is its Charge Attack, which sees it dash forward as it spits out fireballs. But evading this properly will make it trip and fall, providing an ideal opportunity for heavy damage.

Additionally, if you linger beneath it, the monster will unleash a Ground Stomp, pounding the ground a few times — retreating before it starts is the safest bet. The best way to handle this fight is to bait out the charge attack, dodge at the last moment, and punish the stumble animation.

If you're struggling to create an opening, Sonic Pods can be used to disorient it, interrupting its movements and giving you a brief window to strike.

Tips and tricks to beat Yian Kut-Ku in Monster Hunter Wilds

Always bring Water-based weapons for maximum damage. If unavailable, Ice and Thunder work as backup options.
Rolling extinguishes Fireblight — if you get hit by a fireball, dodge repeatedly until the effect wears off. Alternatively, use Nulberries to remove it instantly.
Dung Pods are a must if you encounter multiple Yian Kut-Kus. Fighting more than one at a time is a nightmare.
Sonic Pods exploit its ears, stunning the monster and canceling its charge attack.
Traps are your friend — use Pitfall Traps and Shock Traps to control its movement and land free hits.
Stay mobile — Yian Kut-Ku in Monster Hunter Wilds' attack speed is slow, but its unpredictability can catch you off guard if you’re too aggressive.
