Not sure if anyone mentioned this and it is a bit meta gamey. I would take that Chr and drop it to 15 and bump your str to 14. Let Volo gouge your eye out

. Your int will drop to 8 (8 & 9 are basically the same anyway). That wil bump you Chr to 16. You lose one ASI value but gain 2 ASI value when your Chr bumps to 16.
