I had posted it in the "Future LaTale Content" thread about a week or so I guess, but I don't remember if I ever elaborated on the update aside from the fact that it's Asgard.
The new area is called Asgard. Remember that empty area opposite of the portal to Valhalla waaayyy at the top of Bifrost? That is where the portal to Asgard now is (thankfully, there are save stones in the new areas). The 3 new areas include the Hanger, Hydroponic Gardens, and D-Lab(oratory). The monsters range from Lv14x~Lv162, including 4 new mini-boss/bosses: Loki
(the magician guy from the trailer), Unknown (Girl) and Unknown (Boy)
(the evil-looking artist and monk from the trailer), and Hell herself
(the creepy blonde girl with the lightbulb brain hat). She's the Lv162 `-`;
Other new stuff includes the implementation of 5th skills, a face-lift for the forest mines, and guild crops. The guild crop system works something along the lines of this:
Buy x50 of some item (excuse my laziness to translate the korean trailer right now) from the fashion shop and trade it to Shubur (the guild NPC) for a guild crop seed. Drag said seed into the guild crop window. Then, you can buy fertilizer(?) from Shuber (for ely) to "grow" your guild crop. After you've used enough of that, you then purchase another item from the fashion shop to actually grow your guild crop into a "mature" crop (the various stages of official guild crop art that I'm sure you've all seen). Once it's maxed, you can then enter the guild instant dungeon where your guild crop "comes alive". If you kill it, a crapload of items drop, though the trailer does not show what's in the item bags .-.
Aaand that's about it, along with some some fashions.
