Weaken the Yian Kut-Ku

To successfully catch a Yian Kut-Ku for the New Ecosystems mission, you'll need to weaken it enough for capture. Keep battling with it until you see the signs that it's ready to be captured. If you're not careful, you may accidentally defeat it before catching it.

How to Tell if the Monster is Ready for Capture

Signs that the Monster is Ready for Capture
Your Palico will mention that it looks weak. The monster is limping while fleeing. The monster's heartbeat indicator is flat. There's a skull icon next to the monster's map icon.

Pay attention to what your Palico is saying during the fight as they will mention if the monster is weakening and ready to capture. If they mention that the Yian Kut-Ku looks weak, it's ready for capture!

A monster that's ready for capture will also visibly limp and have panicked or labored breathing when it's moving around, which is also indicated by the flat heartbeat on its monster icon on the lower left part of the screen.

A skull will also appear next to its map icon to indicate that it's close to dying. When this appears, hold off on attacking the Yian Kut-Ku and make preparations to capture it!

Use a Trap and Two Tranq Bombs to Capture

Once Yian Kut-Ku is weak enough to capture, you'll need to lay a Pitfall Trap or Shock Trap to stun the Yian Kut-Ku. Once the monster is trapped, quickly switch to your Tranq Bombs and throw two of it on the Yian Kut-Ku to capture it!

If the monster is sleeping, you can actually use the Tranq Bombs on it first before laying down a trap. Just make sure to move quick as the effects of the Tranq Bombs can dissipate.

Yian Kut-Ku Monster Fight Tips
Bring Sonic Pods to Disorient It Avoid Its Peck Attack as Much as Possible Bring Dung Pods to Make Fights Easier Roll Thrice or Use Nulberries to Cure Fireblight

Bring Sonic Pods to Disorient It

Yian Kut-Ku has large and sensitive ears, making it vulnerable to Sonic Pods. Using one will disorient the Yian Kut-Ku and force it to stay in place. This gives you a window to attack it without fear of retaliation.

The downside is that once the Yian Kut-Ku recovers from the Sonic Pod, it will immediately enter Rage mode, so be ready for that. It may also develop an immunity to Sonic Pods while angered.

How to Use the Slinger

Avoid Its Peck Attack as Much as Possible

The Yian Kut-Ku's peck attack is one of its most iconic attacks and can constantly knock you down if you don't get out of the way immediately. When the Yian Kut-Ku prepares its peck attack, either run away, block the attacks, or get behind the Kut-Ku.

Bring Dung Pods to Make Fights Easier

Yian Kut-Ku often come in monster herds (usually pairs), meaning you might face multiple Yian Kut-Kus. It's best to isolate them from each other for a much easier fight.

In these cases, use Dung Pods or Large Dung Pods fire them off your Slinger to disband the group. Afterwards, focus on hunting one of them.

List of Slinger Ammo

Roll Thrice or Use Nulberries to Cure Fireblight

Yian Kut-Ku can inflict Fireblight with its fire attacks. If your Fire Resistance or Blight Resistance is low, make sure to roll thrice or use a Nulberry to get rid of Fireblight.

You can also roll into bodies of water to quickly put out Fireblight, such as when you are near the streams or rivers of the Scarlet Forest.
