Following the discovery that 75% of MapleStory's in-game marriages end in annulment, Nexon decided to upgrade the wedding system in the newly launched Ascension update. Couples will actually earn rewards for staying married for 30 days, and then again at 100 days. Of course, you'll still have the option to end the union if things aren't working out.
In addition, the Ascension update features class revamps for warriors, magicians and bowmen, as well as new Monster Park dungeons. You can see it all in action by watching the Ascension trailer below.
