Destiny 2's latest weekly reset has taken place on PC, PS4, and Xbox One, marking the end of the latest Faction Rally event and kicking off Victory Week, which means there's a new Legendary weapon available for purchase. Bungie has also shifted the Flashpoint to Titan and rotated the selection of items available at Eververse. Most significantly, the weekly reset has introduced the next Nightfall Strike: Savathun's Song. Here's what to expect in terms of Modifiers, Challenges, and rewards.
