Time: Any
Frequency: Always
World name: Ultros
Character name: Haman Karn
Class/Level: Fisher 60
Area and coordinates: Any fishing location
Steps:
  1. Consume a Cordial or Hi-Cordial item.
  2. Immediately use Patience, Patience II, or Fish Eyes.
  3. The GP cost of the skill is lost before the GP restoration of the Cordial takes effect, giving you far more GP than you would normally have access to under the effect of the skill used, allowing things like using Patience after using Fish Eyes, or many more Hooksets while under the effects of Patience.

Only verified on Windows version, but I do not see why it would not work on PS4 or Mac.
