Resurrect

Death is a truly horrible thing, and only a wonder can return life where death once was. A wonder isn't needed once Resurrect is learned! The spellcaster needs much mana and strength to cast it, but if successful, every wound heals, and the deceased will return to life as if awakening from a bad dream. This makes this spell one of the most powerful ever recorded, but also one of the most taxing ones.

Resurrect doesn't work on victims whose bodies have been turned to ashes, or otherwise destroyed.

Ultima Saga
In Lynn Abbey's Ultima Saga, the Inquisitor Lohgrin threatens to use this spell against Althea. It is said that this spell could have metaphysical repercussions.

Quote

 * "I'd die first. I'd kill myself before I'd let you touch me."


 * His smile broadened. "Such a waste, Althea." He touched her arm lightly with his smooth, dry fingers, then seized it. "A virtuous magician can restore life, at a price. Death need not be permanent."


 * "You wouldn't," Althea whispered. "You wouldn't dare." The Avatar has discovered the secret of Resurrection but the spell confounded destiny in ways neither virtue nor magic could repair. Since the Avatar's withdrawal from Britannia the spell has not been cast.

- from The Temper of Wisdom (Ultima Saga)

Trivia

 * In Ultima IV, the spell is given by Nigel, with a hint to him given by Shazom
 * After Ultima VII, the spell falls into disuse, and other methods of resurrection are found.
 * The Ultima III spell Anju Sermani is a more powerful version of this spell, to be used on bodies that have been burnt to ashes.
 * Care has to be taken to empty a dead party member's corpse of items in Ultima VII before resurrecting them, since it is entirely possible due to a bug that items can get lost. Weapons are especially prone to this bug and it's very annoying when a unique magical weapon just vanishes into nothingness.
