I was about to Theorycraft a Wizard PC with the final goal to become a Lich but I am unsure about what happens to the bonus given from stats to HP.
When in Human form it comes from Constitution, but what happens when you transform?
Does the Constitution stat gets erased and the bonus then comes from Charisma?
My doubt is that it's useless to Theorycraft a Wizard dumping Charisma to 7/8 if you plan to become a lich because you'll lose a whole lot of hit points when you transform.
