if you export a char who have achieved the slayer change..and into a new game as the main char..he will get the bhaal powers again and loose the change....BUT..if you import him to any other space than the first char..he will retain the slayer change..BUT..if you activate it..the main char will turn into the slayer..and he can turn it off again..the human form appearing in the special ability bar...and personally i think the slayer is rather poor..a fully decked up figther or paladin is better..if youre a halforc or dwarf..you can even loose CON..as it goes to 18..the only thing i can see its good for is against kangaxx if you used up all your antimagic scrolls..or the elder brain doors if you dont have crom faeyr
