Morrowind was amazingly versatile. You could combine any effect, and they weren't any safety mechanisms. Want to jump 2000 ft in the air? Don't forget your feather fall spell. Hundreds of ways to kill or die amusingly. My old husk of a brain is having trouble remembering, but maybe some others have a fond memory of their best spell or enchanted item combos.
One of my faves was reflect 100% on self for 1-2 seconds. It acted as a low cost, timed parry and was mega fun to fight mages with.
You can do the same with sanctuary, but any % of sanctuary is useful, and people really sleep on it imo.
ETA: Just remembered another old fave, very low damage fire damage on target, enchanted on something. Because there's no cooldown for the animation of casting from an enchanted item, it was basically a little flamethrower. I liked to put it on my gauntlet and feel like Boba Fett.
