Soul Devourer

Overview

Soul Devourer is a weapon trait on Thorn, an Exotic Hand Cannon, introduced in Season 6. Absorbing a Remnant strengthens Mark of the Devourer and partially refills the magazine. Each Remnant absorbed with the perk boosts the Mark, and the magazine refill helps keep the weapon firing during a fight.

Where it appears

Thorn is the only weapon that rolls it.

Usefulness

It is a weapon-specific trait rather than a general-purpose perk, so its value is tied to Thorn and to the Remnant and Mark mechanics that Thorn uses.
