Magicka is the character resource that is used to fuel spells in The Elder Scrolls III: Morrowind. It has exactly the same purpose that magicka in Oblivion and Skyrim does, and that is being the resource used to cast magic albeit with a few, but major differences. Additionally, magicka may be restored by drinking restore Magicka potions or using scrolls which drain magicka from enemy spellcasters, however these potions can be somewhat uncommon, and quite difficult to find or get for beginning magic-user characters.
