The Black Friday Summon is available for a limited time in November. It includes Heroes from all existing events and all past Heroes of the Month. The Summon Gate does not include Classic (Season 1) Heroes or Hero Costumes.
The summon features 2 brand new Legendary heroes from an upcoming event. There is also a chance to get the current Hero of the Month as a bonus draw.
The Black Friday Summon includes a Black Friday Bonus Chest that is awarded for every 10 summons. You can claim a maximum of 9 chests during the Black Friday Summon. Chest progress does not carry over to the next Black Friday event.
