Summon a Variety of Special Heroes
Special Hero summoning events feature unique Heroes with special outfits designed for various themes or events. This includes Duo Heroes and Harmonized Heroes. During these events, as usual, the appearance rate of 5★ Heroes increases each time you summon five Heroes in a row that are 4★ or lower. These events take place roughly once a month.
