History of Biosphere Explorer Helm

Overview

Biosphere Explorer Helm is a Legendary Helmet from the Biosphere Explorer set, a Titan ritual armor set introduced with Season of the Witch. Its flavor text reads, "Hunger teaches resourcefulness."

Acquisition

Pieces of the Biosphere Explorer set drop one at a time as Universal Ornaments from Vanguard Ops, Crucible (including Iron Banner and Trials of Osiris), and Gambit playlist activities. The set is not sold as a whole, so duplicates are common. One wiki lists Xûr as the helm's vendor, which other sources do not mention.
