Throughout the duration of the event, a Featured Headhunting Banner will open, [Dissonanzen], featuring rate ups for the following Operators:

• 6-Star Mystic Caster Ebenholz
• 5-Star Incantation Medic Hibiscus the Purifier
• 5-Star Marksman Sniper Blue Poison

New outfits will also be made available on the Outfit Store, the Achievement Star Collection for Flametail, Aosta and Kirara:

A new furniture set will also be made available during the event and you can obtain the pieces of the set from the Lingering Echoes event and the Store for a limited time.

Lastly, a special pack, Dissonance Chip Pack, will be available for purchase during the event which includes Caster Chips and LMDs.
