Q293: The Variant Child Template (the one from the D&D Wiki) halves the Hit Dice of the creature. How does apply to a creature with 3 HD? The result of the halving is 1.5 and the template doesn't mention anything about halving down or up the Hit Dice. So, what happens in that case? It counts as a 1 HD creature that substitutes its hit dice for its first level or not?
Q294: If a race mentions "advancement: by character class" do we ommit the Hit Dice it has and thus we do not take its BAB, Saves, Skills and Hit Dice-dependent benefits of its special attacks (if any)?
