This is a Korean RPG Arena based on the game Ragnarok Online.
It uses a Skill System (skills are written down in the objectives), and a Stat System.

The skill system is all according to the mission objectives, written in SOCA style
There are normal skills and transcendental skills (written in lightblue) - Trans skills can be used only after you transcend, by buying the young chrysalis item with level 45.

The Stat Distributing Panel (F2 for centering the view (like the map says)) can be found at the bottom of the map.
