From the altar to the battlefield, Special Heroes dressed as brides are back! You can pick them up with they're available as part of this 5-star summoning focus!
For new summoning events, the first time you summon, you won't have to use Orbs!"
Note: The start and end times for this banner will vary for you. The times I listed are in Pacific Daylight Time.
