It wouldn't be a new FromSoftware game without a grandiose new dragon boss, and Elden Ring Nightreign certainly doesn't disappoint with Caligo, Miasma of Night — also known as the Fissure in the Fog. Out of all the Nightlords you'll face while trying to cleanse Limveld of the plague of Night, Caligo is perhaps the fight with the most impressive spectacle of all.
It's also undoubtedly one of Nightreign's harder bosses, with a Phase 2 that's particularly difficult due to the dragon getting very aggressive and making use of frequent frost attacks that deal high damage and build up Frostbite, too. The good news, though, is that Caligo has two major damage type weaknesses, as well as a relatively simple Phase 1.
