Including a welcome back weekend at the end.
Final Fantasy XI really wants players to log in over the course of December. This month’s game update brings with it a new chapter in the Voracious Resurgence story series. Players who log in daily over the course of December will receive two silver AMAN vouchers per day to participate in the AMAN Trove battlefield offering treasure coffers with powerful gear. Those who log in over the course of December also receive points for rewards including those from previous login campaigns.
And finally lapsed accounts are welcome back from December 25 through January 3 without limit.
