Evolution 3

When you reach level 400, you can't level up further; this is because you need to complete the level 3 evolution quest.

But first, you must complete Marlon's quest. The only classes that don't need to complete this quest are Magic Gladiator, Dark Lord and Grow Lancer.

Marlon can be found in Lorencia, Devias, Noria, and Atlans.

Marlon will ask you to get him a ring, and in the case of the Dark Knight, after you deliver it, he will ask you for another item. Both items can be obtained in Tarkan (by killing monsters).
