History of Wolfpack Rounds

Wolfpack Rounds are Gjallarhorn's exotic intrinsic perk, introduced in Season 15: rounds split into tracking micro-missiles on detonation, and kills spawn an upgraded round. Guides describe it as a heavy damage source against bosses. Pack Hunter grants Wolfpack Rounds to non-Exotic rocket launchers when teammates are near.

They are also the quest items in And Out Fly the Wolves. The quest starts with a round from the Grasp of Avarice dungeon, which you return to Shaw Han. You then collect seven more in the Cosmodrome by defeating powerful Fallen with yellow health bars, and bring them to Shaw Han and Banshee-44.
