[Doremi]

hi guys, i'm new.
I'd like to know if is there any cap skill about classes and clothes.
I mean, if i'm a warrior and i wear a platemail, can i cast some spell like a mage? Flamestrike, lightning bolt etc.?
Can i be a mage/warrior/archer/blacksmither/lumberjacker or is there any restriction about this?
Thank u
