History of Grave Robber

Overview

Grave Robber is a trait: melee kills reload part of the weapon's magazine.

Details

On primary-ammo weapons the ammo goes into the magazine; special and heavy weapons reload from reserves (Shattered Vault). It rolls on Auto Rifles, Hand Cannons, Sidearms and Submachine Guns such as Solemn Hymn and Harmony-21.

Sources disagree

The Destiny 2 Wiki's detailed text says a melee kill fully reloads the magazine, while its short description and Shattered Vault say a portion.
