A short time ago, NCSOFT announced that the "largest update to Blade & Soul since the game's launch" will arrive tomorrow, December 6. The update is entitled "Dawn of the Lost Continent" and will allow players to visit Solak for the next chapter of content.

The level cap has also been bumped up to 55 for players and the cap for Hongmoon is up to 25. I don't know who or what a "Hongmoon" is, but you can level it up more. There's a new solo dungeon, two new six-player dungeons, and even a 12-player raid.

You want the full changelog? I got you covered, no worries. The full list of changes can be found at the Blade & Soul website, broken down by section. Blade & Soul continues to be, as far as I can tell, a free-to-play game with an optional Premium subscription model.
