I didn't really list my build because I wasn't looking for specific help since everything is in the infancy, and I was more focused on the general rules of building a character, which would let me explore a couple of ideas before picking one. Are we allowed to simply not fill one side of the formula, as long as we don't go over on the other side (eg: CR 14, HD 14).
I'm also finding that ANY race that offers an odd number of HD makes the formula impossible, unless I'm misunderstanding? Unless we simply round up CRs so CR 13.5 w/ 16 HD is acceptable.
Right now my first thought is: playing with the idea of the Soul Eater prestige Class (BoVD) and the Vampire/Vampire Lord templates. The latter is +5 CR & 0 HD (combined) -- which is most likely where I'm finding my HD deficiency. Frankly, it's REALLY hard to not also take Monster of Legend when it's opened up to apply to other 'types' -- Perma Haste for +2 CR ALONE would be worth it, never mind all the other stuff you get...
Right now my gist is:
Vampire Template = +2 CR, 0 HD
Vampire Lord = +3 CR, 0 HD
Monster of Legend = +2 CR, 0 HD
14 Class Levels = +7 CR, 14 HD
-- Which leaves me at only 14/16 HD -- but a much stronger build than if I dropped Monster of Legend to fill the gaps, no matter what I did.
