<< Jani in Platinum just informed me she learned the ensorcelling pre-temper potion (and essence of soul) at potions rank 56. >>
Good to know. Recipes for subsidiary ingredients, such as essence of soul, are usually of a lesser rank than the recipe in which they are used, but the guild masters teach the subsidiary ingredient recipe each time you learn a recipe that uses the subsidiary ingredient. Essence of regeneration is a good example of a subsidiary ingredient that a Sorcerer will be taught multiple times. So the point is that essence of soul is probably less than rank 56.
