Thunderer

Overview

Thunderer is the intrinsic perk on The Fourth Horseman, an Exotic Shotgun. It raises the rate of fire significantly and makes the weapon fire full auto, making it a fully automatic shotgun.

Ammo is handled by the perk too. Final blows automatically load ammo from reserves into the magazine, and powerful targets fully reload the weapon.

The weapon's other perk, Broadside, adds more damage to each successive shot in the magazine at the cost of extra spread. The Fourth Horseman is now bought from the Monument to Lost Lights (as of May 2026).
