Elden Ring Nightreign All Bosses: Every Nightlord and Weakness Chart

Elden Ring Nightreign all bosses, in one place: the eight base-game Nightlords, the two Nightlords from The Forsaken Hollows, the final boss and how to unlock him, the Everdark Sovereigns, and the Night bosses you fight at the end of Days 1 and 2. The weakness chart below covers every Nightlord, as of patch 1.03 (checked October 2026).

How bosses work in Nightreign

Every expedition follows the same shape:

1. Day 1 ends with a Night boss.
2. Day 2 ends with a second, harder Night boss.
3. Day 3 is the Nightlord, the expedition's final fight.

Night bosses vary between runs and include returning Elden Ring and Dark Souls bosses. The Nightlord is fixed by the expedition you choose, which is why knowing its weakness before Day 1 matters so much: the two days are your time to find the right weapon.

Nightreign boss weakness chart

Nightlord	Main weakness	Also works	Avoid
Gladius	Holy	Sleep	Fire (about 50% resisted)
Adel	Poison	Sleep, frostbite, scarlet rot	Lightning (about 50% resisted)
Gnoster	Fire	Sleep	—
Maris	Lightning	—	—
Libra	Madness	Holy, fire	—
Fulghor	Lightning	Bleed weapons	—
Caligo	Fire	Sleep	—
Heolstor	Holy	Fire (phase 1), lightning (phase 2), sleep	Poison, bleed, frostbite, madness (immune)
Straghess	Holy, fire	Slash, pierce, sleep, bleed	Lightning, madness (immune)
Harmonia	Sleep	Poison, scarlet rot, blood loss	Madness (immune)

The main weakness is the one to plan your run around. "Also works" is worth picking up if you find it. "Avoid" damage types are heavily resisted, or the boss is immune.

The Nightlords without their own guide

Gnoster, Wisdom of Night (Sentient Pest)

The easiest Nightlord for most teams. Ranged fire builds make short work of him. Deal with the flying moth first, then switch to melee once it fuses with the grounded form. Keep moving: his moving projectiles and swarms reduce your rune rewards if they connect.

Maris, Fathom of Night (Augur)

Also one of the easier fights, and lightning from range dominates it. The key mechanic is his summoning phases. When a floating egg appears above the arena, destroy it in mid-air or get as far away as you can before it detonates.

Fulghor, Champion of Nightglow (Darkdrift Knight)

An aggressive duelist and one of the harder fights. He takes extra damage from lightning, and bleed weapons work well. Circle him and punish after his spin attacks end. In phase two his arm is imbued with poison, and its hits stack damage over time, so avoid taking several in a row.

Caligo, Miasma of Night (Fissure in the Fog)

Weak to fire. Fight near its front legs and bait the claw swipes for damage windows. A frost mist covers the arena during parts of the fight; use light sources so you can still see the attacks coming.

The final boss

Heolstor the Nightlord waits at the end of the Night Aspect expedition. It unlocks once your Trace of Night has four charges, which means defeating four Nightlords: Gladius plus any three others. His two phases and resistances are covered in the Heolstor guide.

Everdark Sovereigns

Everdark Sovereigns are stronger versions of the Nightlords with new moves, added in patch 1.01.3. You must beat the normal version first. Everything about them, including which Nightlords have one, is on the Everdark Sovereign page.

Night bosses in The Forsaken Hollows

The DLC expeditions have their own Night bosses, including Knight Artorias from Dark Souls, Mohg, Lord of Blood and the Demon Prince. Tips for each are on the Dreglord, Balancers and Artorias pages.

Which Nightlord to fight first

• Start with Tricephalos. It is the default first expedition, and beating Gladius unlocks the Duchess, the Goblet vessels and, with the DLC, the new characters.
• Then Gnoster or Maris. Both are among the easier Nightlords and count toward the four needed for Heolstor.
• Leave Fulghor and Heolstor for last. They are the hardest fights in the base game.
