some of these have high gold value, go ahead and sell them. Some of these are fine to just eat so you can tank the effect and level up your alchemy. But the point is, don't stockpile them for potions.
gotchas: skeleton champions are 200 - a waste of a grand soul gem. Ogrim Titans are a waste of a common. Lesser soul gems fit bull netches and *diseased* rats, but I don't know how to tell on sight. The various “dagoths” are all just wastes of Grand soul gems. (except for Ur, who has no soul. apparently.)
