Here a little info about Subclass System, Heros and Third Class Quest (self write)
Subclass System (since C3)
To lvl up a char is only the beginning of l2. A new race is waiting as a reward. If you reach lvl75 you can do your third class quest. Search your right Master (each class another) to find out which classes you can combine. All Subclass-Quests starts at Magister Ladd in the Ivory Tower.
Look here for aviable Subclasses
Hero System (since C4)
The Subclass system is the beginning of the hero system. Do a char reached with his subclass also lvl75 he can start a noblesse quest. With this noblesse quest you are allowed to participate the Olympiade. At this Olympiade you can pvp other members to gain points. The 1 with the most points in a period of a Olympiad will be the Hero of this class. Also other ppl can get Hero Status in other Olympiad periods. The choice of the subclass hasn’t any influence to get Hero Status. Only the primaryclass can participate on a Olympiade.
Third Class Quest (since C4)
As an alternative or as addition you can do your third class transfer quest. At lvl75 you can start your third class quest to get the ultimate skills of this class. If you reach lvl78 you got the highest lvl at C4. Now you can go pvp and hope that C5 soon will come…..
