The Arctic Blast skill sends a jet of icy air out that freezes enemies in their tracks. Many Diablo II players are partial to cold attacks because they not only damage the enemy, but also slow them down and possibly even shatter them. This eliminates them permanently with no chance for resurrection; their corpses cannot be used for nefarious activities (such as Corpse Explosion). For this reason Arctic Blast is very effective against Shamans and Unravelers. This skill does a surprising 8-15 points of cold damage per second over a 5.3 yard radius. It's important to note that this is not a radius effect. Rather, it's a straight line that affects all units in the area of the line (for four seconds). As you put points into Arctic Blast, the damage and range increases and the duration is extended by 0.6 seconds per point. [1]
