Chaos Essence on Yul

So my question is: i can or not to change my yul GS to yul MS and when again to yul GS to get MS 2nd prof skills? Or i just need to lvl up MS as and when change up?

 

No u wont suddenly get rapid fire or any other 2nd prof skill.

 

So what i should do if i whant to be on dark elf race base but with MS 2nd skills?
P.S never done this, so this is new for me.

 

You can't, max you can is get some dark elf base class like iss/othell/sigel/healer etc, and dual archer, but with elf base to have both rapid shot and rapid fire, awaken, then change to GS with chaos essence.

 

This is just for appearence right? Because any classe u can add MS's sub and change to GS with chaos essence and the STATS will be Dark Elf stats, right?

 

Skills, yes, str, dex, con etc, no.

 

But to test i made a GH and put a Dual of MS and the str, dex, con etc are of ELF and not D. ELF (sry for my bad english)

 

Yes, thats right. When you become GS with that dual, you will lose MS + speed passive and gonna get + skill power from GS. Just that.
When it hits 85 and u awaken it, it will become dark elf status(str dex etc).
