Guild Raid on the Holy Night Event

Winter Lunalynn - MementoMori

Face off against Winter Lunalynn in "Guild Raid on the Holy Night" is MementoMori's newest iteration of its occasional guild raid event. It will run from December 13, 2024, until December 23, 2024.

Event Information

Guild Raid on the Holy Night - MementoMori

Guild Raid on the Holy Night features [Holy Night's Fairy] Lunalynn as a Guild Raid boss alongside Sonya and Luke. She's a powerful debuffer that can blunt your witches' damage by lowering their ATK, so she can become a handful to deal with for the unprepared.

To face her in Guild Raid, you will need to spend "challenge attempts" similar to Sonya, though the challenge attempts for fighting her are separate from the challenge attempts for Sonya. Only those who are part of a guild can fight her, so join one as soon as you can!
