I DID THE FOLLOWING WITH THE STORMKEEPER EDITOR:
I just finished the fighter stronghold quest and now want to change my multi class fighter/mage/theif to a human kensai. I created a new character kensai and then copied those attributes to my saved character. My only difference was that I kept the XP which made me a level 9 kensai. So all my spells are gone and I have the same special abilities as a kensai. My question is did I miss any other adjustments that had to be made since I moved up to level 9 from the level 7 character that I just created. e.g. special abilities, weapons, more attacks, etc. In particular, am I missing any character affects? If so, how can I know which to add? My end goal is to continue with the game with my party but as a kensai that will later dual to a mage.
