Arcology Engram

Arcology Engram is a Legendary faction engram from the Arcology faction. It is earned by raising your reputation with that faction. Each engram gives one faction item, either a weapon or a piece of class armor, and one faction shader, New Pacific Rush or New Pacific Sink. It also gives one extra reward: Legendary Shards, or a faction-agnostic Legendary weapon or armor.

Hunters can receive Lost Pacific armor pieces from the faction item, which makes this engram the source for that set. The Attack or Defense values of the decrypted items match your highest possible Light level, with a soft cap of 330.
