The Island of the Sunless Sea is a Nephalem Rift accessed by killing the super unique GrubberGheed's Mentor, which is found in the Treasure Vault, the second level of the Stony Tomb in Act II. The six Sunless Angel minibosses each drops an Angel Bag, which can be transmuted into the Six Angel Bag when all six are gathered, and has a 10% chance to drop the Sunless Crystal Bird, which can be combined with the Six Angel Bag to improve its bonuses.
Lore[]
The place where angels watch, an underground cave miraculously illuminated by sunlight. Was once the staging ground of the heavenly hosts for their crusades into the abyss. When the holy legions were defeated and forced out of the dimension by the forces of Hell, a few human worshippers remained behind to stand vigil. However, heavenly magic is too powerful for mortals to tolerate for long. The mutated, wretched remains of the human defenders were found and embraced by the mighty Lucion, son of Mephisto.
