New Operators (Ebenholz Banner)
6-star Caster: Ebenholz
Ebenholz is a 6-star Mystic Caster who specializes in Damage Per Second. His attacks deal Arts damage to one target. When he is not attacking, Ebenholz periodically stores his attacks, up to a maximum of three, and all of the stored attacks will be released simultaneously at the next time he attacks, which means a burst of four hits! Ebenholz will show his talents especially when Doctors face strong enemies.
5-star Medic: Hibiscus the Purifier
Hibiscus the Purifier is the alternate 5-star version of Hibiscus who is an Incantation. What defines her as an Incantation Medic is that sometimes she will attack enemies instead of healing friendlies. Hibiscus has truly grown up and her skill will now improve the efficiency of her attacks.
5-star Defender: Czerny
Czerny is an Arts Protector that is redeemable in this event. His second skill lets him tank attacks easier than others and punish enemies back with powerful damage, which undoubtedly makes him a good defender worth obtaining.
