Destiny 2’s January update, the game’s first major patch of 2018, will launch alongside the year’s inaugural Iron Banner week, developer Bungie announced today. The event is one of a few elements of the Destiny experience that Bungie is overhauling this month, with the intent of making good on the studio’s recent promises to respond to fan feedback.

The update, which will bring Destiny 2 to version 1.1.2, is set to be released next Tuesday, Jan. 30. Its most important change, arguably, is that Bungie is revamping the reward system associated with raids and raid lairs. The studio is introducing unique perks to raid armor, perks that only function when you’re on the Leviathan. These special buffs — which are broader (and thus, more useful) than the situational perks that the game currently offers — show up on new legendary mods.
