The KR version of AIKA recently added the new Mount System in their latest patch, and here are the mounts for each class. Mounts can be gotten from a lvl 40 quest or through the Item Mall. The appearance of mounts can be change by equipping different “fashion” gears. There are more mounts to come in the future (I have seen a few artwork). By the way, players will not be able to battle while mounted.
