When u take a sub-class u still can use the skills of your older class or u have to reach lv 75 to swich class again to use it? and ever time u want to use u will have to swich class again?
When you subclass it's like a brand new level 40 character, and you can only use the skills/stats of the subclass. You can switch between the main and the sub class at any time in most towns though.
You can swap freely from main class to sub class in town by talking to the grand master for hte class you are trying to switch to.
Yeah, it's sort of like the "Final Fantasy" online game where you can change jobs. Sort of.
Once you get the subclass to 75 (in order to get a subclass you have to get your Main Class to 75 and do some quests) you can then become a Noblesse. From there you can then compete in the Olympiad.
when you sub, your stats and skills change to the class you sub, if you want to go back to your main class you need to talk to grand master, you can't use both classes at the same time ^^
and when you sub, your inventory/WH slots are the sub's inventory/WH. Tatoos are linked to the class too, so when you sub, tatoos you had on main, stay on main. you need to tatoo on your sub (if you want of course)
