Namely Detect Creature. Detect Enchantment. Detect Key.

Even with "Detect Creature" active I still get ambushed now and then but those pesky Cliff Racers, I feel I am missing something.

Not to mention Detect Key,...

Thanks in advance

The detected elements are supposed to show up in the mini-map, but i've yet to see one of these spells work properly.

I have only played with Detech Enchantment, and its all but useless because it can only find enchanted items on people and on the ground, not those in crates and chests and such.
