Nu Udra is a challenging adversary in *Monster Hunter Wilds* due to its massive tentacles, which extend its reach and make dodging attacks difficult. These tentacles are not only within easy reach for melee weapon users but also serve as valuable targets for extra materials upon severing. However, be cautious—these limbs are potent weapons themselves.
Aim for the Mouth
For those wielding ranged weapons, targeting the mouth of Nu Udra is highly recommended despite the challenge of locating it against its nearly pitch-black skin. This spot boasts a 4-star weakness, making it a prime target. Alternatively, the head is another viable option, though it only has a 3-star weakness to ammo damage. It remains an excellent target for blunt and cut damage.
Use Watermoss
Given Nu Udra's affinity for fire in *Monster Hunter Wilds*, it's crucial to use Watermoss. Besides its limb attacks, the boss can unleash fire-based assaults, including setting itself ablaze, which inflicts the Fireblight debuff. Utilizing Watermoss allows you to attack safely without suffering from this status ailment.
Wear Fire Resistant Gear
To enhance your chances of success, equip gear with fire resistance. The Quematrice armor set is recommended as it comes with the Fire Resistance skill. Additionally, consider using decorations like the Fire Res Jewel to mitigate fire damage or the Stream Jewel to boost your water attack capabilities.
Beware of Grab Attacks
Nu Udra's most dangerous move is its grab attack. If you're too close, it might ensnare you with its tentacles, followed by a fiery blast. During the brief pause before the fire attack, you can break free with a knife or target its weak spot using a Slinger.
