| orb does great dmg, but not as much as blizz the only reason why u would choose orb over blizz is cuz orb moves around and makes it easy to attack dispersed groups like those oompa loompa mages in act five shooting flaming cones of peanut brittle at you.
blizz does mass dmg but is a stationary attack so you'll be casting blizz after blizz doing 1000's of dmg but the monster would usually walk through or around it (if they can make it that far) |
