Cold Efficiency

Overview

Cold Efficiency is the catalyst perk for Cryosthesia 77K, a Stasis sidearm.

Effect

Breaking a target frozen by Stasis refills the weapon's magazine from reserve ammo, so the sidearm can keep firing after freezing and shattering targets.

Acquisition

The catalyst is earned through ritual playlist activities: Vanguard Strikes, Crucible and Gambit. Upgrading the catalyst unlocks the Cold Efficiency perk.
