The Arreat Crater

The Arreat Crater is all that remains of Mount Arreat after the destruction of the Worldstone.

It was here that Azmodan and his armies made their way into Sanctuary, laying siege to Bastion's Keep. However, the demons were driven back to the crater, as the Nephalem entered Azmodan's fortifications, and slew the Lord of Sin himself.[1]


The crater appears in Act III of Diablo III. It is split into multiple zones:
