Darkness's Refuge

Overview

Darkness's Refuge is a buff from the Nezarec encounter in the Root of Nightmares raid. Standing in it for about 15 seconds protects you from Nezarec's team-wipe mechanic, but not from attacks.

Acquisition

You create it by taking a Field of Light buff to an inactive Dark node, which you shoot while the buff is active. It is needed when Nezarec's shoulder breaks dark. The opposite buff is the Light's Refuge.

Sources describe the color cue differently: one ties blue to the Light's Refuge and orange to Darkness's Refuge, while another ties a dark shoulder to Darkness's Refuge.
