Question about exchange main / subjob

[Avatha Valiarde]

Hi, I have few questions about exchange main and subjob.

Firstly is it working on x5 ?
And only thing I need is 1200 silvercoin ?

When I have on:
main: adventurer 81
sub: SWS 56
after this exchange I will have:
main: SWS 56
sub: adventurer 80 + 100%
?

And in this case my char will change it's look from human to elves ? Or stay looking like human ?

And last question if I have on main warsmith or overlord can I exchange main with sub or is it blocked for such classes ?

Thx for answer

i wanted to change overlord is not possible same for warsmith all classes that you cant take as subclass maybe will be a problem too if you change to elv and have darkelf subclass but that i dont know.

overlord and warsmith cant be changed cause they cant be subclassed.
all others is possible
also u cant change sub main, if not both classes arent at least 75
