NTE Abyss Guide: How to Beat Mammon in Beyond the Rails

Mastering the endgame of Neverness to Everness (NTE) requires more than just high-level characters; it demands a deep understanding of the Esper Cycle and boss-specific mechanics.

Neverness to Everness Abyss Guide: How to Defeat Mammon

Defeating Mammon in the Beyond the Rails mode is the ultimate test for any Hunter looking to maximize their weekly Fons income and secure high-tier upgrade materials. As the primary gatekeeper of the “Outbound” arena, Mammon utilizes a deceptive mix of lumbering physical strikes and lightning-fast repositioning that can easily catch players off guard. This guide breaks down the essential strategies, team compositions, and elemental reactions needed to conquer this golden anomaly.

Boss Stats

Mammon is the primary endgame boss encountered in the “Beyond the Rails” mode (NTE’s version of the Abyss) and the “Realm of Greed” Anomaly. Unlike standard overworld threats, Mammon in the Abyss features significantly higher Stagger Resistance and a Break Gauge that scales aggressively as you progress through higher Stops.

Understanding the Beyond the Rails “Outbound” Boss

In the Beyond the Rails mode, Mammon serves as the final encounter for several high-tier Stops. Successfully clearing these stages rewards players with Platform Seals, which are necessary for unlocking milestone rewards in the Train Log shop. Because this mode is timed, simply surviving Mammon’s onslaught isn’t enough—you must optimize your damage rotation to deplete his HP before the clock runs out.

Mammon’s Elemental Weaknesses

Mammon’s primary elemental weakness is Lakshana. Utilizing Lakshana-attribute characters is the most efficient way to deplete his Break Gauge. When the Break Gauge is emptied, Mammon enters a “Downed” state, during which he takes 50% increased damage from all sources.

Elemental Damage Effectiveness:

  • Lakshana: 150% Damage (High Break Efficiency)
  • Cosmos: 100% Damage (Neutral)
  • Anima: 100% Damage (Neutral)
  • Other Elements: 75% Damage (Reduced Efficiency)

Attack Patterns

Mammon’s combat style is characterized by “Erratic Melee Aggression.” He often alternates between slow, heavy slams and sudden lunges that can traverse half the arena in a single frame.

Phase 1: Melee Aggression

During the first half of the fight (100% to 50% HP), Mammon focuses on close-quarters combat.

  • Straight-Line Lunge: Mammon lowers his center of gravity and charges forward. This attack has a very long reach. To avoid it, dodge diagonally (45 degrees) toward the boss. Dodging backward will often still result in you getting hit by the end of the hitbox.
  • Erratic Melee Swipes: A 3-4 hit combo using his claws. The first few hits are standard, but the final hit features a distinct golden/white flash. This is your primary window for a Parry Attack, which will significantly boost your Esper Meter and deal heavy Break damage.

Phase 2: Enraged Speed and AoE Slams

Once Mammon drops below 50% HP, he enters an enraged state. His movement speed increases, and the wind-up time for his lunges is nearly halved.

  • Ground Slam (AoE): Mammon leaps into the air and strikes the floor with both claws. This is telegraphed by a large red circle on the ground. You must exit the radius immediately, as the shockwave deals multi-hit damage that can stagger-lock your character.
  • Unparryable Red Aura: Certain attacks in Phase 2 will glow with a deep red aura rather than golden. These attacks cannot be parried. You must use a Critical Dodge to trigger a slow-motion window, allowing you to counter-attack safely.

Identifying Parry vs. Dodge Cues

Success in the NTE Abyss depends on identifying visual cues instantly.

  • Golden Flash: Indicates a parryable attack. Press your Skill or Basic Attack button exactly as the flash appears to trigger a Parry.
  • Red Aura: Indicates an unblockable/unparryable attack. Focus on timing your Dodge to gain the “Perfect Dodge” buff.

Step-by-Step Strategy

To beat Mammon within the Beyond the Rails time limit, you must master the Esper Cycle mechanics. The fight is a race to trigger the “Remora” and “Charge” reactions to keep Mammon controlled and your Ultimates ready.

Step 1: Build the Esper Cycle Meter

Start the fight with your active character (usually your Cycle Battery or Sub-DPS) and use basic attacks and successful parries to fill the Esper Meter. A successful parry against Mammon’s golden swipe will instantly fill a large portion of the bar.

Step 2: Trigger the “Remora” Reaction

Once your Lakshana and Cosmos characters have full meters, swap between them to trigger Remora (Lakshana + Cosmos). This reaction marks Mammon and slows his movement and attack speed for several seconds. This is critical for keeping him in place so your high-damage skills actually land.

Step 3: Focus on the Break Gauge

Use Lakshana-attribute skills during the golden flash windows. Characters like Hathor excel here, as their Lakshana damage is specifically tuned to shred the Break Gauge of anomalies like Mammon.

Step 4: Maximizing the Stagger Window

Once Mammon’s Break Gauge is depleted, he will fall to the ground. This is your “Downed” window. Immediately swap to your Main DPS (such as Nanally) and unleash your Ultimate.

  • Rotation Tip: Swap to Lakshana -> Trigger Remora -> Swap to Main DPS -> Use Ultimate.

Step 5: Time Management in Beyond the Rails

In Beyond the Rails mode, your rewards are tied to the “Time Remaining” target. If the timer is running low, prioritize the Charge reaction (Lakshana + Cosmos + Anima). When a target marked by Remora is hit by an Anima effect, your active character generates massive amounts of Ultimate energy, allowing you to chain Ultimates and freeze the countdown timer during the animations.

Building a team around the Lakshana Meta is currently the most effective way to clear Stop 10 of the Abyss.

Premium Bossing Team

  • Main DPS: Nanally (Anima) – Currently the highest damage dealer for boss execution. Her lightning finger attacks deal massive damage during the stagger window.
  • Sub-DPS/Breaker: Hathor (Lakshana) – Mandatory for her Lakshana attribute. She is the most efficient character for breaking Mammon’s resistance.
  • Cycle Battery: Esper Zero (Cosmos) – Use Zero to quickly fill the Esper Meter and trigger the Cosmos half of the Remora reaction.
  • Support/Healer: Edgar (Cosmos) – Provides essential sustain for Stop 10 clears where Mammon’s chip damage can become lethal.

F2P Alternative

  • Main DPS: Zero (Cosmos) – While usually a battery, Zero can be built for damage in early Abyss Stops.
  • Weakness Breaker: Hathor (Lakshana) – Even at base investment, her elemental advantage is too good to pass up.
  • Utility: Sakiri (Anima) – Provides crowd control and helps trigger the Charge reaction for energy generation.
  • Sustain: Edgar (Cosmos) – The most accessible healer for high-difficulty content.

Loot

Defeating Mammon isn’t just about the challenge; it’s the primary way to progress your city management and character power.

Fons and Covetous Coins

Fons is the primary currency for city management, vehicle upgrades, and purchasing property. The amount of Fons you earn from Mammon scales with how much HP you deplete within the time limit. Covetous Coins are a specialized drop used to level up the “Blind Mammon” plushie (Anomaly Furniture). Upgrading this furniture increases your weekly Fons cap and unlocks harder versions of the boss for better rewards.

Beyond the Rails Milestone Rewards

Clearing Mammon in the Abyss grants Train Logs based on your Platform Seals (1-3 stars per Stop). These can be exchanged in the Mall for:

  • Elite Hunter Guides: Used for high-level character ascension.
  • Chaotic Dyes: Required for customizing vehicle and gear aesthetics.
  • Annulith: The premium currency used for character banners.

Upgrading the Gluttonous Eye

There is a rare chance for Mammon to drop “Gluttonous Eye” components. These are used for home customization and to further enhance the “Realm of Greed” furniture, allowing you to farm Fons more efficiently during your weekly resets.

Mall Exchange Priority:

  1. Annulith (Always clear this first)
  2. Elite Hunter Guides
  3. Covetous Coins (if not capped)
  4. Chaotic Dyes
