Farming recommendations

  • Loot only becomes permanent when you extract — a drop you don't extract is worth nothing.
  • With no reliable rate published, don't trust any "guaranteed in N runs" claim you see elsewhere.
  • Rates are bound to their mode and difficulty — check the source context before comparing.
