Hello,
I am currently high elf. If I change my race to Breton what will happen to all my skill lines (combat and crafting)? And what will happen to my racial skill line? I will need to increase race skilline from zero?
All Your skills (except racial) will remain the same
Racial skill points will be refund to you, all you need to do is reinvest them in your new ones (but you will have level 50 in racial skills already, so you can do it right away)
