Following the update, the first Everdark Expedition came in the form of Augur, which turned out to be an incredibly divisive topic among the Elden Ring community. And following Augur, the next boss is going to be Caligo, who is the one boss in the game that needs the Everdark variant the most.

While regular Caligo isn’t a cakewalk, it certainly is easier compared to other Nightlords, especially when contrasted againstGladius,Adel,Fulghor, andLibra. However, that will change with Everdark Caligo, which seems to be significantly more difficult than its base version.
