All game servers will be down for maintenance on Wednesday, November 13th, 2013, at 5am PST / 7am CST / 8am EST / 1pm UTC/GMT. Estimated downtime is approximately 4 hours.
With this maintenance:
The Memorable Raid Boss Pack, Raid Boxes and the Raid Boss Accessory Pack will be on sale until November 20th. Raid Boss Accessory Packs do not begin to rundown the 14-day timer until you open them, so you can stock up on the packs while they're still available.
If you have any questions about the changes taking place during tomorrow's maintenance, please feel free to post them on the Lineage II forum.
