- Preview of the Cavern of Echoes(src)
The Glacial Colossus is a super unique monster seen in Diablo Immortal. It is the boss of the dungeon; Cavern of Echoes.
Lore
Within the Cavern of Echoes waits the Iceburn Tear, a stone that emanates a cold as potent as death. Legend holds that its guardian is born of the frostbitten flesh of those who sought to claim the stone's power. The glacial colossus is ever-growing, and so connected to its charge that, if it should crumble, its entire domain would follow suit.[1]
In-game
The Glacial Colossus is the boss of the Cavern of Echoes dungeon in Diablo Immortal. Similar to the Realmwalker from Diablo III it can hide underground with only its dorsal horns — with the Iceburn Tear held between them, exposed. After its minions are killed it comes out of the ground to fight the player, only to retreat underground again after receiving significant injuries.
