Attack the Tentacles

Facing Nu Udra in *Monster Hunter Wilds* is no easy feat. Its massive tentacles give it a wide reach, making dodging its attacks a challenging task. However, these tentacles are the closest limbs accessible to melee weapon users. By severing them, you can obtain valuable materials, but be cautious—these limbs are potent weapons in their own right.

Aim for the Mouth

Ranged weapon users have a variety of targets, but the mouth is the prime spot to hit. Despite its almost completely pitch-black skin making it hard to spot, the mouth boasts a 4-star weakness, making it a prime target. The head, while only having a 3-star weakness to ammo damage, is still a great spot for blunt and cut damage.

Use Watermoss

Given Nu Udra's fire affinity, it's not just its limbs you need to worry about; its fire-based attacks can be devastating. At times, the boss will even ignite itself, causing the Fireblight debuff that makes close combat dangerous. To counter this, using Watermoss to douse the flames is highly recommended, allowing you to attack safely without suffering from the status ailment.

Wear Fire Resistant Gear

Struggling with the fight? Equip gear with fire resistance. The Quematrice armor set, featuring the Fire Resistance skill, is a solid choice. Additionally, consider using decorations like the Fire Res Jewel to reduce fire damage or the Stream Jewel to boost your water attack capabilities.

Beware of Grab Attacks

Nu Udra's arsenal includes a terrifying grab attack. If you're too close, it might ensnare you with its tentacles and follow up with a stream of burning fire. During the brief pause before the fire attack, use a knife to break free or target its weak spot with a Slinger.

How to Capture Nu Udra in Monster Hunter Wilds

To capture Nu Udra in *Monster Hunter Wilds*, you'll need either a Pitfall or Shock Trap. Before setting the trap, you must weaken the monster by attacking it until it's on the brink of death, indicated by a skull icon next to the boss icon. You can use meat as bait to lure Nu Udra into the trap, or simply lead it there while it's targeting you. Once trapped, swiftly use a Tranquilizer to put it to sleep—you have about five seconds before it breaks free.

That's all you need to know about defeating and capturing Nu Udra in *Monster Hunter Wilds*. Given the challenge of facing this monster alone, consider using multiplayer to increase your chances of success.
