Set charms in Diablo 4 are mainly farmed by pushing higher Torment content, especially Torment 3 and above, then using the Horadric Cube to convert duplicates into the pieces you still need. The most common sources mentioned are The Pit, Infernal Hordes, Undercity, and boss farming.

Fast farm route

  1. Run content at Torment 3 or higher, since drop rates improve there and multiple set charms can drop from a single boss.
  1. Prioritize The Pit, which several guides call the best overall farm, then use Infernal Hordes, Undercity, and boss runs as backups.
  1. Save duplicates instead of salvaging them immediately, because extra copies are useful for cube recipes.

Cube methods

  • Use the 3-to-1 transmutation : place any 3 charms into the Horadric Cube to get 1 random set charm.
  • Use reroll set charm when you already have a duplicate from the same set and want to hunt the missing one.
  • Salvage unwanted charms for materials, then spend those materials on rerolls.

Practical loop

A simple farming loop is: clear high-Torment content, collect duplicates, salvage the weak ones, then cube the extras until you complete the set. If you’re targeting a specific set, the fastest path is usually to farm lots of charms first, then reroll within that same set rather than hoping for a perfect drop.

Useful note

Some community posts also mention farming on an alt by sharing surplus set pieces from your main and then finishing them with cube recipes, but that’s more of an optimization than a requirement. The core idea is still the same: farm high-Torment drops first, then use the cube to reduce randomness.

  • YouTube guide on farming and completing set charms in Lord of Hatred Season 13.
  • YouTube guide explaining Torment 3+, boss drops, and rerolling via the Horadric Cube.
  • Community discussion mentioning Undercity, The Pit, and rerolling duplicates.

TL;DR: farm Torment 3+ content, focus on The Pit and boss runs, keep duplicates, then use the Horadric Cube’s 3-to-1 and reroll recipes to finish the set faster.
