Howling Blast is a Death knight ability that allows the death knight to blast several targets around them for frost damage. While the tooltip damage may seem low, it benefits from your Attack Power.
Patch 4.1.0 (26-April-2011): Damage has been increased by 20%. To compensate, the area-of-effect splash now does 50% of the single-target damage, down from 60%. The net result of this change leaves the area-of-effect damage roughly the same as 4.0.6 numbers. In addition, Howling Blast now has a facing requirement.
/Patch 4.0.1 (2010-10-12): Cost reduced to one frost rune, down from one frost and one unholy.
Patch 3.1.0 (2009-04-14): Base damage and scaling doubled.This ability no longer deals bonus damage to targets with Frost Fever. 8-second cooldown. Swapped positions with Hungering Cold in the talent tree.
Patch 3.0.8a (2009-01-27): The 5 second cooldown will now display correctly.
