This Armsday's Rank 1 selection for Eirene is actually super nice, not only for things like it's Luck in the Chamber for Crucible one-hit white kills, but also for: Luck in the Chamber Injection Mold Zen Moment The synergy of these three perks is actually fantastic in Vanguard content versus Ultras. Encounters with the Warpriest and Golgoroth in King's Fall have players across the globe maintaining critical accuracy to optimize damage results. Now, a combination of Zen Moment and Injection Mold allow players to maintain that lethal vector, and even get an 8% total damage increase for the 4-round magazine. Please keep these things in mind when selecting your Eirene RR4 Sniper Rifle, courtesy of the Omolon Foundry.
