Dukaan (Mask)

Dukaan is a dragon priest mask found in.

Acquisition
This dragon mask can be acquired from the remains of Dukaan, one of four named dragon priests on Solstheim. Dukaan can be encountered at the Nordic ruin of White Ridge Barrow.

Enchantment
Dukaan's unique enchantment is called "Zahkriisos' Ire". It grants bonuses to frost damage and resistance:
 * Resist Frost: 50%
 * Augmented Frost

In addition, weapons that bear a frost damage enchantment are also boosted by 25%. Like most unique enchantments, Dukaan cannot be disenchanted.

Smithing
It can be upgraded with an ebony ingot at a workbench, and also benefits from the Daedric Smithing perk, which doubles the improvement.

Usefulness
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 of Skyrim, so the increase in damage dealt may not be as useful.

On the other hand, a Nord wearing this mask would be rendered almost immune to frost damage, as elemental resistance is capped at 75%.
