Are you wanting to try out Tera on your console? If so, you can get double xp from May 18, 2018 to May 28, 2018. The double XP applies to killing monsters including dungeons. Paying players also get the bonus XP.
This applies on to the Playstation 4 and Xbox One, although I wish it included the PC as well.
More info can be found at Tera’s website.
