NTE Complete Boss Bestiary: All 18 Main / World / Hidden Bosses — Weaknesses & Strategies

Quick answer: NTE currently has 18 bosses — 7 main-story, 7 world, 2 weekly, and 2 hidden. The key to fighting bosses is “weakness element + adjacent elements on the cycle” (to trigger resonance reactions like Blossom / Discord / Charge). The 6 best world bosses to farm cover every standard S-rank signature weapon (Serenetti → Camellia Society, Swallowtail → Reality Shelter, Black Tome → Youthful Fantasy, Headless Rider → Raging Flames, Nestbound Bird → Tears Behind the Mask, Arachne → Eternal Waltz). The hidden boss Hethereau Guardian rewards a universal S-rank Arc that is a must-have for F2P players.

NTE’s boss design follows a dual axis of “action parrying + elemental reactions,” and every boss has a clear elemental weakness plus a specific way to counter its moves. This article lays out the complete bestiary for all 18 bosses.

Main-Story Bosses (7)

1. Picture Frame (Prologue I)

• Location: the Anomaly space where Alice’s Bakery is located
• Weakness: Anima
• Mechanic: a parry and stagger-break tutorial fight — high HP but simple moves, with obvious red-light attack telegraphs
• Recommendation: your team is limited at this stage, so Mint (your only Anima unit) leads the attack; make full use of Parry + Critical Riposte to trigger stagger-break
• Difficulty: beginner-friendly ⭐

2. Taygedo (Prologue II)

• Location: during the Prologue II story
• Weakness: no elemental weakness — mainly a stagger-break fight
• Mechanic: once its stagger gauge hits zero it enters a downed state; it throws nearby objects at the field, and you can counter those objects and hurl them back at the boss for massive damage
• Recommendation: a Charge team (Nanally + Hathor + Esper Zero + Edgar) to trigger the Charge resonance loop

3. Film-MANISH (Prologue II)

• Location: the “Brand Anniversary” Anomaly in Prologue II
• Weakness: Cosmos; Cosmos + Anima triggers Blossom
• Moves:
  • Flash Light (flashing needle stab): a white light flares → Critical Dodge, then you can land a long combo after dodging
  • Red Circle Slam (double red-circle ground slam): parry the moment the two red circles converge and turn yellow
  • Frontal Laser: slows you on hit; sidestep laterally to avoid it
• Tactics: melee for Break, with Parry + Critical Dodge to build your gauge

4. Imaginadough (Chapter 1)

• Location: the Azure Vista camp on the Shore of the Unheard-Of
• Weakness: Chaos
• Mechanic: HP-threshold splitting — at around 70% HP it splits into 2, and when low it splits again into 3. All clones share the same health pool, so focusing fire on a single body is the most efficient
• Recommendation: Daffodill (Main DPS) + Haniel + Sakiri + Fadia → the Discord resonance loop

5. The Never-Ending Arachne (Chapter 2 + Weekly)

• Location: outside the Ebisu Auction House on the Shore of the Unheard-Of
• Moves:
  • Flower shockwave → jump or Critical Dodge to avoid it
  • Laser attacks → reposition during the attack gaps
  • Phase 2 dark room mechanic: you must stay inside the “light circle” or you get frozen in place
  • The final slash can always be parried, and a successful counter staggers the boss
• Recommendation: a Daffodill team (Daffodill + Sakiri + Haniel + Fadia)
• Rewards (weekly): Hunter EXP, Scarab Coins, Advanced Hunter’s Guide, Colorless Dye, Vanity Cuffs, Arcane Thread

6. Debt Collector (Chapter 3)

• Location: inside the Dolores Mansion Anomaly in the Miguel District
• Weakness: Cosmos
• Mechanic: long wind-ups and wide-sweeping attacks; your characters are locked on first encounter (Nanally, Esper Zero, Daffodill)
• Tactics: every long-wind-up move can be dodged; all surrounding-type attacks can be parried — just time your Basic Attack to counter

7. Zankou (Chapter 4 — 1.0 Final Battle)

• Location: the Dolores Mansion Anomaly, unlocked after completing the “Debt Collector” chapter
• Background: a core member of the Crimson Letter crime organization and the final boss of the 1.0 main story
• Weakness: Incantation
• Moves:
  • Phase 1: slow heavy strikes and short combos that can be read; the raised-sword charge wave can be parried back
  • Phase 2: summons 4 phantom clones that charge in sequence, each requiring only 1 Critical Riposte to destroy
• Recommendation: a Hexed team (Nanally + Sakiri + Adler + Mint) or a Discord team (Baicang + Daffodill + Sakiri + Fadia)
• Difficulty: hard ⭐⭐⭐

World Bosses (7) — ⭐ Key: They Cover the Standard S-Rank Signature Weapons

1. Serenetti

• Location: Shore of the Unheard-Of - Serenetti Manor greenhouse
• Unlock: the side quest “Where Worlds Sprout, Fall Unfolds”
• Weakness: Incantation
• Mechanic: a fixed-position boss (it does not move) whose attacks cannot be parried — a pure dodge fight
  • At HP < 50% it goes berserk: a flood of speech bubbles appears around it, with dense bullet patterns + AoE, and it heals itself
• Rewards: Hunter EXP, Scarab Coins, Confessional Flower Seed (material for Baicang’s signature weapon “Camellia Society”), Arcane Thread

2. Swallowtail

• Location: New Helland District - Floe Cinema (the cinema projection room)
• Unlock: the Anomaly commission “Let’s Go See a Movie”

3. Black Tome

• Location: New Helland District - Kyllene Trail (phone booth)
• Unlock: the Anomaly commission “The Book of Post-Adolescence”
• Weakness: Chaos
• Mechanic: chain attacks briefly root you in place, so dodging is key
  • Red circle telegraph: timing a Parry on your Basic Attack stuns the boss
  • HP < 50% Phase 2: gushing chains + falling-door binds
• Rewards: Coal Lump’s Gift (containing A Page from Delusion’s Shore, material for Daffodill’s signature weapon “Youthful Fantasy”)

  • Tire Crush: always the second hit of a combo; when you see the red light, counter the third hit
  • Aerial Charge: high mobility + tracking

5. Beat King

• Location: the park near Fiscus Boulevard in Mirage Town
• Unlock: the Anomaly commission “Rhythm Master”
• Weakness: Psyche
• Core mechanic: a rhythm-game beat battle — hitting the prompts in time with the Notes deals burst damage
  • Two rhythm patterns appear mid-fight, which you need to learn
  • After HP < 50%, a Parry can counter the flying-disc charge, knocking down the boss to create a damage window
• Recommendation: Jiuyuan is the best — she can run Blossom for sustained damage and keep attacking even while the body is rooted
• Rewards: Crystals, Scarab Coins, U-00NE, Silver Vine, Magic Thread

6. Sea Prisoner

• Location: New Helland District waters / Nautili Tunnel area
• Unlock: the Anomaly commission “Deep Blue Sorrow” (requires a four-wheeled car to pass through Nautili Tunnel)

• Location: New Helland District - Pink Paws Bank

• Rewards: Good Boy Stamp (material for Sakiri’s signature weapon “Good Doggo Goes Far”), Arcane Thread

The Element Cycle and Resonance Reactions (Must-Know for Bosses)

The 6-Element Cycle

Cosmos → Anima → Incantation → Chaos → Psyche → Lakshana → back to Cosmos

The 8 Resonance Reactions

Reaction	Element Combo	Effect / Signature Team
Blossom	Cosmos + Anima	Steady DPS trigger, Jiuyuan’s signature
Discord	Psyche + Incantation + Chaos	The core of the Daffodill team, breaks stagger
Charge	Anima + Cosmos + Lakshana	The Nanally team, restores Ultimate energy for the whole team
Remora	Cosmos-based	Follow-up damage
Hexed	Anima + Incantation	Nanally + Sakiri synergy
Stain	Lakshana + Psyche	Hathor’s mainstay
Accumulate	special mechanic	Adds EX Rail Finisher
Scorch	Chaos + Incantation	DOT damage over time

Key to fighting bosses: build your team with the weakness element + adjacent elements on the cycle to amplify damage + break stagger + trigger the Ultimate loop all at once.

Beginner Boss-Challenge Priority

Ordered by “reward value + difficulty gradient”:

1. Nestbound Bird (Skia’s signature weapon “Tears Behind the Mask”) — easier, just bring a Cosmos character
2. Headless Rider (S-rank Arc “Raging Flames,” blue-flame cosmetic) — mind the 00:00-04:00 + four-wheeled-car conditions
3. Swallowtail (Jiuyuan’s signature weapon “Reality Shelter”) — airborne, needs ranged attacks
4. Serenetti (Baicang’s signature weapon “Camellia Society”) — pure dodge fight
5. Black Tome (Daffodill’s signature weapon “Youthful Fantasy”) — chain roots, be cautious
6. The Never-Ending Arachne (Fadia’s signature weapon “Eternal Waltz”) — hard, Phase 2 needs a strong team
7. Hethereau Guardian (universal S-rank Arc) — the final challenge, high-difficulty Lv 99
