All Protocol Spaces and Locations
Severe Energy Alluviums
Severe Energy Alluviums are harder versions of Energy Alluviums, and cost Sanity to begin the challenge.
Clearing one rewards the player with Flawless Essences, which can be etched onto an Operator's weapon and potentially grant additional buffs.
