Back in February, I first posted (link) about the new class after Academic, Kali. As the update for this new class approached the Korean server some time in June and July in apparently 2 separate updates, more news were released with a teaser trailer to boot.
While no physical weapons were shown, it is said that she is a skilled mid-range mage using a resource call chakra (same as Naruto). You can see some of her skills in the trailer above, which includes summons which will attack for her and provide buffs as well. I shall not translate her background story to avoid spoilers, but just know that it is all about revenge, as seen in the poster below.
Another part of the content update will obviously be new dungeons/ nests. While there are no new dragons now, 2 level 60 nests will be updated for the high level players. A trailer is shown below.
