Farming Preparations

  1. Identify the Best Source: The Sources below are generally ranked from best to worst. Make sure to complete any required quests and be aware of Source Restrictions.
  2. Locate the Source: Make sure you have unlocked the Location.

  • Track Progress: Track your runs to more precisely predict drops and more clearly monitor progress. Additionally, time your runs to see how tweaks affect your farming efficiency.
  • Speed it up: Explore shortcuts and boost your movement speed to minimize travel time. Also, aim to shorten your time to kill with higher DPS or big damage bursts.
  • Realistic Expectations: Be patient and persistent when farming. Despite precise, verified drop rates, your actual runs might exceed or fall short of inferred expectations.
