I really liked how in Mabinogi everything is explained and has a reason (there is even a reason why all the monsters are carrying gold) except maybe the expiration of enchant scrolls. So let's try to explain stuff in Vindictus, especially ones that differ from Mabinogi.
In Mabinogi you can be everythig at once, in here you must specialize in a single class and a single expertise. In Vindictus the player characters are human. The milletians in Mabinogi have probably all the time in the world.
The transformations here last for just 2 minutes, while in Mabinogi one can maintain a transformation for hours. Maybe the Silent Brotherhood found a way to access a pseudo-transformation without having to done the armor. That way it doesn't need the sun to recharge and is usable every hour and is also usable by giants. Side effects include very short duration, having to transform while transformed to reach a higher level, breaking completely the user's armor. This or milletians are just too powerful. Not much details are given on that, Nyle just snaps his fingers and the player suddenly knows kung fu.
The wisps have started absorbing erg crystals and have become smart enough to have their own language and it gave them powers to shoot lightning o_o
How are the players unable to die permanently if they are not milletians?
