Dear Tibian,
Continue your journey with 7 days of free Premium Time and an XP boost by
logging in to the game before Jan 09, 10:00 CET, 2019.
December and January have a lot to offer in Tibia:
In addition to new quality of life features, the winter update grants you
access to the mystical realm of the dream-born elves.
Faster respawn rates between Dec 07 and Dec 10 and an extended double
XP/skill weekend around Christmas spice up this festive month even more.
During the new annual event Winterlight Solstice, which starts on Dec 22,
you can face the percht queen on her frozen throne.
The isle of Nostalgia invites you to walk down memory lane as we celebrate
Tibia's birthday on Jan 07.
Log in to Tibia before Jan 09, 10:00 CET, 2019 to claim your gift. We'd
love to see you again!
