Vindictus players will gain a new hero today in the form of Miri, "a powerful character with an ancient connection to the potent dragons of the past". She uses a weapon called Dragonspire and can heat up any location with her fiery abilities.
In addition, Vindictus players can take part in holiday fun with special events alongside a number of gameplay improvements. Nexon will be unleashing a series of giveaways each Saturday from December 9th through January 7th. Players will also be able to leverage Double XP for the first three weekends after Miri's release. Lastly, the guild system has been reworked and new auxiliary equipment is becoming available to all.
