Awaken adds +2 HD, int increase, and slight charisma bump. On an otherwise already combat-statted animal, such as a dire lion, how much would the CR change for awaken? I assume it would just be +1. Animal HD are normally +1 CR for every 3 HD. Changing over to magical beast will give it immunities to a lot of 'animal' spells, so that alone is probably enough to make up for it.
Does that sound about right?
