Talk:Enchanting (Oblivion)

I haven't tried trapping a soul yet in Oblivion, though I did it in Morrowind. Besides the level of the gem (petty, common, etc.), doesn't it also make a difference what kind of creature the trapped soul belonged to? In other words, rats souls are less powerful than wolf souls, and scamp souls are higher than both of those. This correlates with gem level too, with petty soul gems suitable for rats, but common sould gems for scamps, or something like that, right?
