Elden Ring Nightreign Nightlord Boss Guide All 8 Bosses

Nightlords are the final bosses of each expedition in Elden Ring Nightreign — the co-op roguelike spin-off from FromSoftware and Bandai Namco released May 30, 2025. Each three-day expedition culminates in a Nightlord encounter on Day 3, with the specific boss determined by the expedition type chosen at the start of the run. The base game features eight Nightlords, and the Forsaken Hollows DLC adds two more. This guide covers all eight base-game Nightlords: the expedition that leads to them, their elemental weaknesses, key attack patterns to watch for, and phase-two survival priorities. Boss mechanics can change with patches — cross-check the Bandai Namco patch notes for your current version.

01How Nightlord Fights Work

Nightlord fights are multi-phase encounters that begin immediately after a Day 3 cutscene. Each fight follows a structure:

• Phase one: The Nightlord uses its core moveset. Damage output and attack speed are at baseline.
• Phase transition: At a specific HP threshold (roughly 40–50% HP depending on the boss), a cutscene or dramatic shift triggers. The Nightlord typically becomes faster, gains new attacks, and may change its elemental properties.
• Phase two: The Nightlord's full moveset is active. Many fatal attacks appear only in phase two — learning the specific tells for each boss's most dangerous phase-two move is the primary learning objective for first-time clears.
• Stagger system: Nightlords have a poise bar that can be broken through sustained heavy attacks, colossal weapon strikes, and Raider's Totem Stela. A staggered Nightlord is briefly opened for a critical hit — coordinate stagger windows in trio for maximum damage.

Night's Tide does not shrink during the Nightlord arena — the fight space is fixed. You should not need to track the boundary once the boss fight begins.

02Gladius, Beast of Night — Tricephalos Expedition

Gladius is a three-headed beast and the first Nightlord most players encounter, tied to the Tricephalos expedition. It serves as an introduction to Nightlord pacing and telegraph-based attacks.

• Weakness: Holy damage.
• Resistance: Physical attacks deal reduced damage due to heavy natural armor.
• Key phase-one pattern: Wide claw swipes that track your position for two to three hits before stopping. Do not roll immediately — let the combo complete two hits and then dodge the third.
• Phase-two change: Gladius gains a ground slam that sends a wave across the arena. Roll towards the boss (into the slam) rather than backwards to avoid the wave.
• Preparation: Any weapon with Holy infusion or Holy damage scaling significantly shortens this fight. If running a fire or lightning build, expect longer time to kill.

03Adel, Baron of Night — Gaping Jaw Expedition

Adel is highly resistant to most damage types and requires either Poison status accumulation or persistent elemental pressure to kill efficiently. New players who stumble into this expedition with an unprepared build will find the fight frustratingly long.

• Weakness: Poison buildup is the primary damage mechanism — Adel takes significant bonus damage once Poisoned.
• Resistance: Broadly resistant to most elemental and physical types outside Poison.
• Key pattern: Adel uses a grabbing attack that deals massive damage if caught. The grab has a slow wind-up from a crouched position — once you recognise the stance, roll sideways immediately.
• Phase-two change: Adel's attacks gain Poison status application, meaning you can accumulate Poison on your own character from melee exchanges. Keep Neutralising Boluses in your inventory.
• Preparation: Weapons that apply Poison (Rotten Greataxe, Venomous Fang, or any bow with Poison arrows) accelerate this fight dramatically. Recluse's Magic Cocktail can apply Poison affinity if elemental cycling is used correctly.

04Gnoster, Wisdom of Night — Sentient Pest Expedition

Gnoster is a dual-creature boss — two separate enemies sharing a single health pool fight simultaneously throughout the encounter: Gnoster itself (a flying moth) and Faurtis Stoneshield (a scorpion-like creature). They do not take turns; both are active from the start.

• Weakness: Fire damage.
• Phase one: Gnoster (moth) attacks aerially with magical projectiles, poison mist, and orbital beams. Faurtis (scorpion) attacks on the ground with pincer strikes, stomps, and charges. Both deal damage simultaneously — split attention between managing the aerial projectiles and the ground creature's melee.
• Phase transition (at ~50% shared HP): Gnoster descends and lands on Faurtis Stoneshield's head. The two creatures now move and attack in coordination, launching combined charges while simultaneously releasing projectiles. This window has a long animation — use it for free damage.
• Phase two: The combined creature attacks faster and uses both the scorpion's melee patterns and the moth's projectile patterns in sequence. There is no form change with separate elemental resistances — Fire remains the primary weakness throughout.
• Preparation: A fire-primary weapon is effective throughout the full fight. Positioning to hit both creatures simultaneously when possible makes the most of the shared health pool.

05Maris, Fathom of Night — Augur Expedition

Maris is considered one of the more frustrating Nightlords for melee-focused Nightfarers because the boss spends significant time airborne and at range, making consistent damage application difficult.

• Weakness: Lightning damage.
• Resistance: Limited status effect vulnerability — Bleed and Scarlet Rot accumulate slowly.
• Key pattern: Maris frequently retreats from melee range and fires water-based projectiles from the air. The projectile spread is wide but telegraphed — move perpendicular to the line of attack rather than directly away.
• Phase-two change: Maris's attacks gain faster projectile velocity and the boss adds a dive attack that covers most of the arena. The dive has a long wind-up animation with a clear shadow beneath the impact point — move to the shadow's edge.
• Preparation: Ironeye's ranged kit (Lion Greatbow, Single Shot) is the most naturally suited for Maris because it can damage the boss during airborne phases where melee cannot reach. Equip Lightning-infused weapons for any Nightfarer.

06Libra, Creature of Night — Equilibrious Beast Expedition

Libra is a defensive-oriented Nightlord with notable resistance to Magic damage. Holy and Fire damage are the primary elemental options; Madness status buildup causes an additional burst of frenzy damage when the bar fills.

• Weakness: Holy damage (primary elemental weakness), Fire damage (secondary), and Madness status buildup — inflicting Madness on Libra triggers a large burst of frenzy damage and briefly staggers it.
• Resistance: Magic damage is notably reduced. Standard physical, Strike, and Pierce damage are neutral; only Slash physical is slightly effective.
• Key pattern: Libra uses a balance-beam shaped limb to swing in a wide arc. The swing can be rolled through, but the follow-up stomp hits a tight radius — move away after the swing roll.
• Phase-two change: Libra activates a gravity-manipulation move that pulls players toward it before releasing a burst. When the pull begins, dodge towards and past Libra rather than away — the burst radius is centred on Libra's position.
• Preparation: Holy-infused weapons or incantations are the most reliable damage option. Frenzied Flame incantations and Madness-inflicting weapons add burst damage when the status procs, but Holy damage is more consistently available in Limveld.

07Fulghor, Champion of Nightglow — Darkdrift Knight Expedition

Fulghor is widely considered the most mechanically demanding Nightlord in the base game. The fight is characterised by extremely fast startup frames on most attacks and a boss that moves continuously around the arena striking with multiple swords.

• Weakness: Lightning damage.
• Resistance: Minimal elemental weaknesses overall — only Lightning deals notably increased damage.
• Key pattern: Fulghor's multi-sword flurry attack begins with a brief arm-raise animation before releasing five to seven rapid hits. The only safe response is rolling through the first hit with good timing and repositioning — blocking is possible but exhausts stamina rapidly.
• Phase-two change: Fulghor gains a Nightglow aura that increases the range of all sword attacks by approximately 30% and adds a trailing projectile to each swing. Maintain maximum dodge distance and only attack in confirmed recovery windows.
• Preparation: Fulghor is the expedition that rewards practice over optimised builds. Learn the multi-sword flurry tell first. Wylder's Sixth Sense passive provides one free mistake per day, making this boss significantly more learnable for newer players.

08Caligo, Miasma of Night — Fissure in the Fog Expedition

Caligo is a status-resistant fog entity. Most status effects (Bleed, Scarlet Rot, Madness, Poison) accumulate very slowly or not at all, making direct elemental damage the primary offensive strategy.

• Weakness: Fire damage.
• Resistance: All status effects accumulate significantly more slowly than against other Nightlords.
• Key pattern: Caligo uses miasma cloud zones that deal damage-over-time while you stand in them. Avoid standing inside cloud zones — identify clear ground and fight from it, rotating as Caligo repositions.
• Phase-two change: Caligo spawns smaller miasma clouds across the arena progressively, reducing the safe area over time. Prioritise keeping at least one safe path open to the Nightlord for melee access.
• Preparation: Fire-infused weapons perform best here. Recluse's Magic Cocktail Fire affinity and fire incantations both maintain good damage output throughout. Bring Clarifying Boluses to counter any fog-induced status buildup.

09Heolstor, the Nightlord — Night Aspect Expedition

Heolstor is the true final boss of Elden Ring Nightreign and the most complete combat challenge in the base game. The fight has two phases with shifting elemental resistances and a moveset that demands knowledge of multiple attack types.

• Weakness: Holy damage in phase one; resistances shift in phase two.
• Phase-one moveset: Heolstor uses wide melee swings with long reach and delayed follow-up hits that punish early rolls. Wait for the full combo to end — typically three to four hits — before counterattacking.
• Phase transition: At approximately 50% HP, Heolstor undergoes a dramatic transformation. This transition window is safe but brief — deal damage during it without overextending.
• Phase-two moveset: Heolstor gains access to Night-element attacks that deal heavy damage and can one-shot lower-HP Nightfarers. The Night Aspect's tell is a dark aura that builds around its weapon before release — dodge immediately when you see the aura begin.
• Night elemental resistance shift: Phase two reduces Heolstor's Holy weakness. Maintain Fire or Lightning damage sources as supplemental options if Holy damage becomes less effective.
• Preparation: Heolstor rewards running your strongest possible build rather than expedition-tailoring. The Night Aspect expedition is unlocked after clearing other Nightlords first — use the experience from earlier encounters to prepare your relic loadout and weapon choice.

In trio play, Duchess's Finale (obscures the team from tracking) is particularly effective at the phase-two transition — it provides a safe window for the whole team to apply damage without Heolstor targeting anyone.

10General Nightlord Preparation Tips

These tips apply to every Nightlord regardless of which expedition you are on:

• Know the elemental weakness before the fight. Check the expedition type before confirming your expedition and ensure your primary weapon or build addresses the Nightlord's weakness. A weapon that deals the wrong element type can extend the fight by several minutes.
• Never enter Day 3 with less than three Sacred Flasks. Use Crimson Tears during Days 1 and 2 conservatively — flask count does not reset between days, only between expeditions.
• Break poise when possible. All Nightlords can be staggered. Raider and Wylder with colossal weapons apply the most consistent poise damage. Coordinating a stagger window in trio for a critical hit can remove 15–20% of the Nightlord's HP in one burst.
• Learn the first three attacks before committing offensively. Every first encounter with a new Nightlord should start with observation. Identify the most dangerous attack before trying to maximise DPS.
• Phase transitions are safe — use them. The cutscene or dramatic pause when a Nightlord enters phase two is almost always a free-damage window. Apply damage immediately rather than waiting to re-learn the fight from a neutral position.
