Harmony affects the frequency of Varagies while Knowledge can help you combat that. I’ve done my own tests on both to obtain information that isn’t prevalent in the game.
General Info
Harmony affects the rate of Minor Varagies in the game but it’s effect on the type of Varagies is unknown. Knowledge, using the Council, can be used to combat or predict Minor and Major Varagies. Throughout my gameplay I noticed odd things about Knowledge and I was curious about what actions affected Harmony so I conducted some tests using custom mode and below are the results.
