2023-01-11, 08:30 UTC: Due to a technical issue, this month's Ninja Summon was not featuring the correct set of Heroes.
A fix for the issue has just been deployed, and it should go into effect for all players in less than half an hour. To immediately apply the fix to your game, please restart your app now.
Please rest assured that the results of any Ninja Summons conducted prior to the fix will NOT be affected in any way.
We apologize for the inconvenience. Thank you for your understanding!
