Events are unique maps that appear for a limited time. These make up the majority of new content for the game. The goal of most events is to farm for units and exclusive equipment that doesn't drop in the Main Story and collect event currency to exchange for Units, Equipment, Fodder, etc.
From 17/08/2021, old Events can be added permanently to the game. Permanent Events have the same Unit / Equipment drop as before, but Event Currencies / Event Exploration and Event Exchange are not available.
From 04/07/2023, Event Currencies in all subsequent Events will be REMOVED when after the said Event ends, including Event Rerun.
