Hellfire can it crit?

[nodoze]

Wouldn't a frost mage mage blizzard be more dps? (and does that crit?)

No Blizzard does not Crit and the base damage is less than Hellfire and the spell lasts half as long so you will need to switch windows twice as much to sustain DPS. A decent option if you want less spamming and less window switching than repeatedly spamming AE across multiple clients for sure but still twice as much switching as Hellfire.
