This has nothing to do with skills and abilities. It changes nothing with your character, it just changed the way their attacks look with particle effects and trails.
I propose an idea if you master a class (Get it to level 60) you should be able to have unique skills that you can cross-class to give them different aesthetics.
For example:
Master Dark Knight (Level 60 and complete all quests.) gives you an item which you can slot on your character for every class:
Slotted to a Dragoon:
Dark Lance attacks and Darkness animations from lance.
Slotted to a Paladin
Dark Crusader, Flash and most aesthetics and particle affects and trails are turned to be more like Dark Knights.
Slotted to a Scholar
Turns Faerie into a Dark Faerie, two different types. Healing has a dark effect to it.
Slotted to a Bard
Dark Arrows!
It could be limited to mix certain classes with each other of course but it could be cool!
I would love for example, to slot a Warrior Soul on my character to give my Dark Knight more warrior-like effects. That is if I mastered both Warrior and Dark Knight.
I would also love to play Paladin with Warrior or Dark Knight effects on them, the Paladin effects hurt my eyes which is why I avoid the class. That is however my reward for being a level 60 Warrior and DRK and Paladin.
