There's more than these two, but most are connected to Daedra, so don't exactly fit the bill of mortal magic. I guess undeath isn't an option? Off the top of my head: Molag Bal's quests in Oblivion and Skyrim, attempted resurrection of Potema in Skyrim, Mankar's Ascended Immortals, The Waking Nightmare quest in ESO (specifically Prince Adrien, others were mindless). Possibly the Grace of Courtesy in Morrowind, but I think we're being saved from the brink of death, not actually dying. Also Mere-Glim in The Lord of Souls, whose soul was captured beforehand and put back into a regrown body. Briarhearts might qualify too, but I'm not sure how much humanity they retain.
