When I stepped into the Fissure in the Fog Expedition after battling Gladius in Tricephalos, I didn't expect Caligo, Miasma of Night, to be such a beast. At first glance, this massive icy dragon seemed like a pushover compared to other Nightlords in Elden Ring Nightreign. But man, was I in for a rude awakening! Caligo isn't just big—it's got this aggressive streak that feels personal, like it's out to punish me for even daring to challenge it. That initial confidence vanished when it lunged at me, frost breath swirling like it was mocking my unpreparedness. I remember thinking, 'This ain't gonna be a walk in the park,' and boy, did it deliver. The arena was freezing cold, and the sheer scale of Caligo made me feel like an ant fighting a glacier. Every roar echoed with this eerie sense of dread, making my heart race as I fumbled with my gear. If you're not ready, this Nightlord will chew you up and spit you out, no questions asked. 
Discovering Caligo's Weaknesses
Caligo's got a soft spot for fire, which is a godsend because it staggers him big time when you pile on enough heat. Fire weapons are pretty common if you know where to look—places like Greater Churches and Encampments often have them lying around. But here's the kicker: sometimes RNG hates you, and no fire spots spawn in your Expedition. When that happened to me, I almost panicked, but I remembered equipping a Relic that turns your starting armament into a fiery beast. Talk about a lifesaver! It felt like striking a match in a blizzard—suddenly, Caligo wasn't so invincible. Bleed is another ace up your sleeve; seeing that Blood Loss proc feels oh-so-satisfying. Characters like Executor start with a katana, so you can slice and dice from the get-go. Personally, I love the thrill of landing a bleed hit—it's like watching the dragon's icy facade crack under pressure.
Navigating Caligo's Attack Patterns and Phases
Almost every move Caligo pulls deals ice damage, so your Frostbite bar fills up faster than a snowdrift in a storm. 😅 I learned the hard way that fighting at medium range is key—it keeps you close enough to rush in when he breathes ice in an arc, but far enough to dodge that nasty downward breath or Icy Gale. After chipping away at his health, he pulls this disappearing act, covering the whole arena in fog. You can't see squat—only your teammates' name tags glimmer like ghostly beacons. This fog phase is where Caligo gets sneaky: if you hear ice crackling above, brace for a massive disc-shaped ice attack. My first time, I froze (pun intended!), but now I either bolt away or charge straight at him for some damage while he's channeling—it's risky, but heck, fortune favors the bold! Or, if you spot a black trail zipping toward him, follow it and duck behind ice structures to avoid his sweeping ice breath. After losing half his health, Caligo amps up with icy winds and changing music—this second phase is chaos! Ice shards litter the ground, slowing you down and cranking up Frostbite buildup. When he takes flight and shoots crystals, dodging like a maniac saved my skin—each hit isn't deadly, but a barrage? No thanks!
Boosting Your Chances with Events and Teamwork
If you're lucky enough to trigger the Mountaintop Shifting Earth event, go for it! Completing it halves Frost buildup and damage, making the fight way more manageable. I scored this once, and wow—it felt like swapping ice skates for heated boots. Plus, it gives bonus attack power if you inflict Frostbite, which is cool but not super useful against Caligo himself.
Picking the right team is crucial—fire and bleed are your bread and butter. Here's my go-to lineup:
| Character | Role | Why They Rock |
|---|---|---|
| Wylder | Top DPS | His Relics spread fire after Ultimates and allow follow-up fire attacks—total game-changer! |
| Executor | Bleed Specialist | With the right Relic, he deals fire and bleed simultaneously, plus his parry avoids damage. |
| Recluse | Mage Support | She amps fire spells and uses others' fire to boost Magic Cocktails—epic for burst damage. |
Raider's Ultimate can shield you from projectiles, but swapping him in depends on who you bench—I usually drop Recluse if I need defense.
Rewards and Lingering Thoughts
After finally toppling Caligo and wrapping up the Expedition, the rewards are sweet: Relics, Murk, and the Night of the Miasma Relic. This bad boy is clutch—it conceals you when Frostbite procs nearby, changes armament skills to Chilling Mist, and boosts attack against frostbitten foes. It's like Caligo's own tricks turned against him! But not every class can use that skill, so it's a bit hit-or-miss. Standing there in 2025, loot in hand, I can't help but ponder: What other icy horrors lurk in the Nightreign? How will these strategies evolve as we face even fiercer Nightlords?
