Hail of Verglas: Unique Power and Affixes

What makes the Hail of Verglas so good? This helm is crafted to supercharge your Ice Shard Sorceress. The most critical aspect of the item is its unique effect and synergy with the Ice Shards' core skill.

Unique Effect:

Adds +2 Additional Ice Shards to your casts.
Each Ice Shard gains 1-2% increased damage for each time Ice Shards damages an enemy in the last 5 seconds.

This bonus scales multiplicatively, making it extremely potent against clustered enemies or bosses with large hitboxes.

Affix Rolls (may vary slightly per item drop):

Affix 0:

+7.5% Maximum Cold Resistance
+50% Cold Resistance

Affix 1:

+4 to +6 Ranks in Ice Shards

Affix 2:

+10.5% to +15% Intelligence

Affix 3:

+10.5% to +15% Attack Speed

Affix 4:

+8.1% to +8.8% Maximum Life

These stats greatly improve survivability, cooldown performance, and overall Ice Shard effectiveness. The +Ranks to Ice Shards means your skill will scale faster and buy duriel mats hit harder, especially with lucky drops close to the top of the roll range.
