How to beat Caligo, Miasma of Night in Elden Ring Nightreign

Caligo, Miasma of Night, is one of the most formidable Nightlords in Elden Ring Nightreign, serving as a major story boss in the late-game expedition. This four-winged dragon wields devastating frost-based attacks, including the dreaded Frostbite debuff, making the battle a true test of skill and preparation.
If you're struggling against this icy behemoth, our comprehensive guide will help you exploit Caligo’s weaknesses, avoid deadly mechanics, and secure victory.

Caligo, Miasma of Night – Boss Overview

As one of the eight Nightlords, Caligo is a high-difficulty encounter with multiple gimmick mechanics that require precise timing and strategy. Key traits of this boss include:

• Frostbite Infliction – Rapidly drains stamina and health if not resisted.
• Aerial Assaults – Frequently takes flight, forcing players to react quickly.
• Fire Weakness – Highly susceptible to fire-based attacks, making them essential for breaking its stance.

Best Preparation for the Fight

Before engaging Caligo, optimize your party and gear to counter its frost-based onslaught:

Recommended Relics & Gear

• Frostbite Resistance Relics – Essential to mitigate the boss’s debuff.
• Fire-Infused Weapons – Exploit Caligo’s weakness to fire for faster stance breaks.
• Ranged Characters – Duchess and other ranged units can safely deal damage from a distance.
• Tanky Frontliners – Wylder or similar high-defense characters can absorb hits.

Essential Pre-Fight Tips

• Stock Up on Fire Damage Sources – Collect fire-enhancing items from Limveld before the third day.
• Upgrade Defensive Gear – Maximize survivability to endure Caligo’s hardest-hitting attacks.

Caligo Boss Fight Strategy – Step-by-Step Guide

Phase 1: Ground Combat

• Stay Underneath Caligo – Most of its melee attacks can be avoided by positioning yourself beneath its body.
• Focus on Fire Attacks – Continuously deal fire damage to break its stance, opening it up for critical hits.
• Watch for Frost Breath – If Caligo rears back, dodge sideways to avoid its cone-shaped frost attack.

Phase 2: Aerial Assaults

When Caligo takes flight, the arena will be covered in fog, signaling one of two deadly attacks:

Freezing Sky (Frostbite Crash)

• Indicator: The sky begins freezing over.
• Solution: Sprint to the far end of the arena to avoid a massive frost explosion.

Pillar Ice Barrage

• Indicator: The sky remains dark but doesn’t freeze.
• Solution: Quickly hide behind pillars to avoid a devastating ice storm.

Phase 3: Stagger & Critical Hits

• After breaking Caligo’s stance, target its head for a critical strike, dealing massive HP damage.
• Repeat this process while managing Frostbite buildup to steadily whittle down its health.

Rewards for Defeating Caligo

Upon victory, you’ll earn:

• Fissure in the Fog (Elden Ring Nightreign Trophy)
• Unique Nightlord Rewards (High-tier loot for endgame progression)

Final Tips for Success

• Learn Attack Patterns – Caligo’s moves are telegraphed; memorizing them will help with dodging.
• Stay Mobile – Avoid staying in one spot for too long to prevent Frostbite accumulation.
• Use Fire Liberally – The more you exploit its weakness, the faster the fight ends.

By following this guide, you’ll be well-equipped to conquer Caligo, Miasma of Night, and advance further into Elden Ring Nightreign’s gripping endgame.
