Baleful Fragments in Diablo 4 come from salvaging Legendary weapons at the Blacksmith, and the reliable route is to farm more Legendary weapon drops first. They’re mainly used to upgrade Legendary weapons.

How to get them

  • Salvage Legendary weapons at any Blacksmith.
  • Focus on weapon-heavy loot sources like Helltides , Tree of Whispers , Nightmare Dungeons , and Murmuring Obols gambling for a better shot at more Legendary weapons.
  • Helltides are especially efficient because you can target weapon caches and open many reward chests in one run.

Important detail

  • One guide notes that Baleful Fragments only drop from Legendary weapons with at least 400 item power , not from armor or jewelry.
  • So if you’re short on fragments, it’s usually better to salvage spare Legendary weapons instead of selling them.

Fast farming loop

  1. Run content that drops lots of loot, especially Helltides or dungeons.
  1. Keep any Legendary weapons you don’t need.
  1. Salvage them at the Blacksmith.
  1. Repeat until you have enough Baleful Fragments for upgrades.

TL;DR

Salvage Legendary weapons at the Blacksmith, then farm more Legendary weapons through Helltides, dungeons, Whispers, or Obols to keep the fragments coming.
