As we can read in the steparu’s blog players have already been gathering information from the new Lost Ark site. They have discovered 10 small videos that will show us some of the beginning and advanced classes that will be playable during the closed beta. Supposedly the game would have 3 initial classes and a total of 18 classes.
Although we don’t have many details about what classes are or are not available during the next august beta in korea Here we leave you the video with a look at the variety of classes in this game.
