Skyrim Mod:Mod File Format/SPEL

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:

• Charge Time: The longest Casting Time of all of the effects.
• Spell Cost: The total of all effect costs.
