History of Fighting Lion

Fighting Lion is a Void Grenade Launcher Exotic designed by Wei Ning, who called it "the Zhang Fei."

Overview

• Archetype: Grenade Launcher in the Energy slot, but uses Primary ammo instead of Special, so it has effectively infinite ammo. To balance that it has a very slow reload.
• Historically it was weak at launch, improved in the Curse of Osiris era, was dominant in the Crucible around Season 14, and received its slow reload in Season 15 (per Destinypedia).

Acquisition

• Exotic engrams and extremely rare world drops.
• Can be reacquired via Collections, and was a staple Haunted Forest-era reward in older guides (older source; verify current availability in game).

Catalyst

• Drops randomly from non-Guardian enemies.
• Adds Chimera: after the weapon fires, equipped Kinetic and Power weapons briefly gain increased handling and accuracy; also faster reload.
• Sources disagree on the masterwork requirements: Destinypedia says 500 kills and 250 bounties, Game Rant says 1,000 kills and 2,500 bounties. The numbers may have changed over time; check the in-game catalyst.
