Yes — for goblin spawn chance , difficulty does not really matter in Diablo 3. Goblins can appear on Normal, Torment, and everything in between; the main reason to raise difficulty is for better loot, not a higher goblin spawn rate.

What changes with difficulty

  • Goblin spawn rate stays essentially the same across difficulties.
  • Higher difficulty can improve rewards like Blood Shards, materials, and overall loot quality.
  • For cosmetic goblin farming, many players prefer the easiest difficulty they can clear fast, because speed matters more than toughness.

Best farming approach

  • Run fast zones and reset quickly instead of slowing down for fights.
  • Check high-value cave and multi-level areas, since those are common goblin routes.
  • If you can comfortably speed-farm on a higher difficulty, that is fine — it just should not be chosen for goblin spawn chance alone.

Simple rule

If you are farming goblins, pick the difficulty where you can move through areas the fastest. If you are farming for loot at the same time, then bumping difficulty can make sense.

TL;DR: No, difficulty does not meaningfully affect goblin spawn rate; farm on the fastest difficulty you can comfortably clear.
