Frost Nova is a somewhat handy skill for Sorceresses of the lower levels (and occasionally of higher levels and skill). Though not recommended as a primary skill, this can be used when you are low on mana and need to run for the hills, as it slows a wide range of enemies for a reasonable duration.
Lore[]
Like the Lightning Nova, this spell is effective against large groups of swarming melee attackers. Although less damaging than its electrical kin, the immobilizing effects of the cold can convey other advantages.[1]
