Attacking Nu Udra's Tentacles

Nu Udra presents a formidable challenge in Monster Hunter Wilds. Its extensive tentacles grant it impressive reach, making evasion tricky. However, these same tentacles offer melee fighters their closest access point. Severing its arms yields valuable materials, but caution is advised—these limbs are potent weapons themselves.

Targeting the Mouth

Ranged weapon users have more tactical options. The optimal target, however, remains Nu Udra's mouth. Its near-total black coloration makes it difficult to spot, but the effort is worthwhile. The mouth boasts a 4-star weakness. The head is another viable target, though it only has a 3-star weakness to ammo damage, but remains effective for blunt and cut damage.

Utilizing Watermoss

Nu Udra possesses a fire affinity. Besides its limb attacks, it employs fiery assaults. At a certain point, it even ignites itself, creating a dangerous proximity due to the Fireblight debuff. Using Watermoss is highly recommended to mitigate this risk and enable safer attacks.

Equipping Fire-Resistant Gear

Struggling against Nu Udra? Prioritize fire-resistant gear. The Quematrice armor set, with its Fire Resistance skill, is a strong recommendation. Fire Res Jewels significantly reduce fire damage, while Stream Jewels boost water attack damage.

Avoiding Grab Attacks

Nu Udra’s grab attack is particularly perilous. If you're too close, it will ensnare you with its tentacles, followed by a fiery blast. During the brief pause after the grab, use a knife to break free, or counterattack its weak point with a Slinger.

Capturing Nu Udra

To capture Nu Udra, prepare either a Pitfall or Shock Trap. However, deployment requires weakening the monster to near-death. Look for a skull icon next to the boss icon to signal the opportune moment. Luring it with meat or simply running behind the trap while it targets you are both effective strategies. Once trapped, immediately use a Tranquilizer. You have approximately five seconds before it breaks free.

That concludes your guide to defeating and capturing Nu Udra in Monster Hunter Wilds. This hunt is challenging solo; consider utilizing multiplayer for assistance.
