Know Your Enemy: Weaknesses & Resistances

Unlike regular Nu Udra, the Arch-Tempered version has tougher elemental resistances but retains the same core weaknesses—with one critical difference: it punishes over-aggression with new oil ignition and double ground slam patterns that can cart you instantly.

Elemental Weaknesses (Prioritize These)

Pro Tip: While raw damage builds still work if you’re patient, Water weapons provide the most consistent damage output throughout the fight.

Status Vulnerabilities

✅ Sleep – Great for wake-up burst damage combos
✅ Paralysis – Creates safe damage windows
✅ Blastblight – Consistent chip damage during combos
✅ Poison – Passive damage over time
✅ Exhaust – Forces stamina depletion for longer openings

Essential Skills to Equip

• Partbreaker: Speeds up tentacle and limb breaks for staggers
• Weakness Exploit: Maximizes critical hit damage on weak spots
• Flayer: Increases part break efficiency
• Guard/Guard Up: Blocks flame AOEs (for Shield weapons like Lance, Gunlance, Charge Blade)
• Fire Resistance 20+: Reduces chip damage from lingering flames
• Adaptability Level 2: Counters continuous heat terrain damage

Pre-Hunt Preparation: Items & Gear

Essential Items Checklist:

• Nulberries (10+) – Clears Fireblight instantly
• Mega Potions (10) – Primary healing
• Energy Drinks – Stamina recovery for extended dodge chains
• Armorskin/Demondrug – Defense/attack buffs
• Might Seeds – Temporary attack boost for burst phases
• Cool Drinks – Negates heat damage (critical!)
• Shock Trap + Pitfall Trap – Interrupts enraged combos
• Tranq Bombs – Capture if possible (not all Arch-Tempered monsters can be captured)

Pre-Hunt Meal: Eat an Insurance Meal (Felyne Insurance) before starting to get one free cart—this hunt is unforgiving, and you’ll likely need that safety net.

Phase 1: Oil Ignition Opening (0-30% Health)

The fight begins with Nu Udra’s signature move: oil spill AOE into immediate ignition, covering a massive area in lingering fire. This creates continuous chip damage and applies Fireblight even through Fire Resistance.

Opening Strategy:

• Stay at mid-range until the initial flames clear
• Pop a Cool Drink immediately to counter heat damage
• Aim for 20+ Fire Resistance minimum before starting
• Target the head and tentacles during recovery windows after flamethrower sweeps
• Use Nulberries the moment Fireblight procs to avoid back-to-back burn ticks

Key Openings:

• Right after oil ignition (3-4 second window)
• After short flamethrower sweeps (face vulnerable)
• Post-charge recovery (tentacles exposed)

Avoid: Staying directly underneath—chip damage stacks fast and will burn through Mega Potions.

Phase 2: Enraged Combo Chains (30-60% Health)

Once Nu Udra enters its enraged state (indicated by red glow and increased aggression), attack patterns chain together with minimal recovery time. The signature move here is the double ground slam combo that covers 70% of the arena.

Critical Survival Tips:

• Don’t panic roll after the first slam—the second follows immediately and will hit you mid-recovery
• Keep mid-range distance and watch for the wind-up animation
• Superman Dive through the second slam if caught too close (sheathe weapon + dodge while running away)
• Use Area 14’s environmental traps:
  • Falling Stalactite: Triggers for ~3,800 damage in multiplayer (massive burst window)
  • Sleeptoads: Activate for guaranteed sleep status → wake-up attack combo

Target Priority:

• Melee hunters: Focus forelimbs and tentacles for trips
• Ranged hunters: Prioritize weak spots (head) when it recovers from combos

Trap Usage: Save Shock Traps and Pitfall Traps for interrupting its most dangerous combo chains—these create 8-10 second safe damage windows.

Phase 3: Final Stand (60-100% Health Depleted)

When heavily damaged, Arch-Tempered Nu Udra unleashes both flame AOEs AND ground slams more frequently, plus it emits constant heated terrain that drains HP passively if you’re too close.

Advanced Tactics:

• Stay hyper-mobile—standing still = guaranteed cart
• Guard Up weapons (Lance, Gunlance, Charge Blade) can safely block AOEs, but positioning is still critical
• Use your biggest burst attacks after the double slam finishes (longest cooldown period—6-7 seconds)
• Deploy remaining traps to interrupt enraged combos
• Coordinate with teammates: one hunter distracts while others focus weak spots

Desperation Moves to Watch:

1. Triple Oil Ignition: Three consecutive oil pools → immediate ignition (covers entire arena)
2. 360° Flame Sweep: Spins while breathing fire (Superman Dive required)
3. Slam + Tail Swipe Combo: Ground slam followed immediately by tail spin (wait for full animation before approaching)

Rewards: Why This Hunt Is Worth It

Defeating Arch-Tempered Nu Udra rewards rare + tier materials essential for endgame gear:

Guaranteed Drops:

• Nu Udra Certificate y (quest reward)
• Nu Udra Certificate S (carve/break reward)

Common Drops:

• Nu Udra Hide+

• Nu Udra Spike+

Rare Drops:

These materials unlock the final upgrade tiers for Nu Udra weapons and Alpha+ armor sets, making this hunt mandatory for completionists.

Top 5 Tips from Expert Hunters

1. Adaptability Level 2 Is Non-Negotiable Without it, the heated terrain in Phase 3 will drain your HP faster than Mega Potions can heal. Slot it via armor or decorations.

2. Water Weapons > Raw Damage While raw builds work, Water-element weapons like Uth Duna (Great Sword) or Water Artian Lance provide 15-20% more damage consistency across all phases.

3. Focus Tentacle Breaks Early With Partbreaker equipped, tentacle breaks trigger staggers that create 5-6 second damage windows—crucial for aggressive weapon types like Dual Blades and Sword & Shield.

4. Superman Dive Saves Lives Master this technique: sheathe weapon → sprint away from monster → dodge while running. You’ll become invincible during the entire dive animation, perfect for escaping instant-kill AOEs.

5. Use Environmental Damage in Area 14 The Falling Stalactite deals fixed massive damage and doesn’t scale with defense—trigger it during Phase 2 for a guaranteed stagger and 10+ seconds of free damage.
