Destiny 2's Season of the Undying continues to unfold week by week, and more new content is on its way with the next weekly reset. We're seeing the toughest waves of the Shadowkeep expansion's Nightmare Hunt activity showing up, as well as a new quest for a rare and unique Exotic weapon: Leviathan's Breath.

Bungie detailed the first month of live content in Shadowkeep and the Season of the Undying on its content calendar, which includes Nightmare Hunts; a new dungeon; the upcoming Halloween event, Festival of the Lost; and the Final Assault portion of the Vex Offensive activity. As Bungie noted in its latest This Week at Bungie blog post, the Leviathan's Breath quest becomes available on October 22, kicked off by visiting Banshee-44 in the Tower.

We already know a little about what to expect from Leviathan's Breath. The Exotic weapon is a Void bow that uses Heavy ammo. It's capable of firing heavy bolt that can stagger unshielded enemies. When the bow is fully drawn, it also creates a concussive blast that knocks back enemies.

It's not clear what the Exotic quest will require players to do, although the name Leviathan's Breath suggests it's related to Cabal Emperor Calus. If recent quests are any indication, it'll probably include several steps--including one or two specific missions. The mission is only available if you've purchased the season pass for the Season of the Undying, though. It was included with Shadowkeep, but if you're playing the free-to-play New Light version of Destiny 2, you're out of luck for Leviathan's Breath.

We'll have a full guide for Leviathan's Breath after it releases with Tuesday's weekly reset. In the meantime, there are more Exotic weapons to track down in Shadowkeep and the Season of the Undying. Those are Deathbringer, a Hive-themed rocket launcher that works more like a mortar, and Divinity, the Garden of Salvation Raid trace rifle that includes a lot of puzzle-solving.
