Bonus Catalyst Weekend! Ranking up your Artifacts? This bonus weekend should help! Catalysts are always available for Marks of Victory from John Constantine in your HQ or in the Marketplace. This weekend, ALL Catalysts also have a chance to drop as rewards in Episode 33: Atlantis' daily On Duty content, and are guaranteed to drop in Atlantis' weekly On Duty content. Play this latest episode's instances (event, normal, or elite versions), and stock up on those Catalysts! Catalyst rewards are obtained when you complete each instance. The Bonus Catalyst Weekend will begin this Thursday (February 14, 2019) with daily server restarts, and will last through Monday (February 18, 2019), to daily server restarts on Tuesday morning.
