History of Phaseglass Refraction

Phaseglass Refraction is a common destination material on Kepler, introduced with Destiny 2: The Edge of Fate.

Where to find it

Crystal shards stick out of rock in The Gorge, unlocked after the first two Strangelets in the campaign. They are also found in the Assimilated Easement and in The Stellar Sink. Defeating the boss Cyclops Rampant, Conductor's Chosen drops 7.

Uses

It is traded at the Altar of Relativity for focused decoding of Kepler gear. The required material rotates daily, so players stockpile all Kepler materials, and Fated Ciphers are needed too.
