The Prophecy league ran from June 3, 2016 to August 29, 2016.
Cross Navali's palm with silver and she will tell your future, divining a Prophecy for you to fulfill. These Prophecies will take you to the farthest reaches of the continent as you strive to achieve your destiny.
The Prophecy league and Hardcore Prophecy league was a pair of challenge leagues. The leagues started on June 3, 2016 along with the release of Version 2.3.0 and ended on August 29, 2016. There were 40 optional challenges. Completing the challenges rewards the player with a unique Prophecy Footprints Effect, a unique Prophecy Weapon Effect, and a unique Navali's Monkey Pet at 12, 24 and 36 completed challenges respectively. Completing 19 or more challenges also rewards the player with a unique hideout decoration, the Prophecy Totem, which will grow bigger the more challenges are completed.
In this league, approximately one monster per area could drop a Silver Coin. These can be traded with Navali, who can exchange one silver coin for a prophecy. Prophecies have various effects: they can add new enemy encounters to zones, improve crafting outcomes, guarantee a unique drop, and so forth. There are even prophecies that require the player to have a certain unique item equipped, which upgrades the unique item when completed.
At the end of the leagues, all characters and stashes will be moved to Standard league and Hardcore league. Characters that die in the Hardcore Prophecy league will immediately be moved to the permanent Standard league.
