From my experience the jumping fire spiders do about as much as a fireball spell. The poison ones do about the same as a single poison rune. That flawless gems do about twice the damage. I havent had good experiences with any of them except the jumping ones which are great stealth bombers. The biggest issue I have is it takes like 3-4 to kill a single opponent on master difficulty, well getting enough gems to use them as a primary form of offense is just tedious and unrealistic. After the initial 'fun' and unique concept of using them they tend to become more of a burden than they are worth.
