Skyrim Mod:Mod File Format/ALCH

Internally, all alchemy items (food, drinks, potions, and poisons), enchantments, ingredients, scrolls and spells derive from the same object, MagicItem, and thus share a similar structure.

Auto-calc: The auto-calculated potion value is the total of all effect costs. The CK displays the sum of rounded down costs, while the game uses the rounded down value of the exact sum to determine the gold value of a potion.
