Dukaan's unique enchantment is called "Zahkriisos' Ire." It grants bonuses to frost damage and resistance:
In addition, the augmented frost damage effect not only affects frost spells, but also shouts such as Frost Breath and Ice Form, plus it even increases damage of weapons that bear a frost damage enchantment. Like most unique enchantments, Dukaan cannot be disenchanted.
Much like its counterparts Zahkriisos and Ahzidal, Dukaan benefits mages who favor frost-based attacks. However, frost resistance (or, in some cases, even immunity) is not uncommon among the enemies in Skyrim, so the increase in damage dealt may be less noticeable.
On the other hand, a Nord or late-stage vampire wearing this mask would be rendered almost immune to frost damage, as elemental resistance is capped at 85%.
