Darksight Helm is a unique Basinet. Allowing the use of the useful skill, Cloak of Shadows, Darksight Helm can be particularly helpful for a melee fighter by blinding ranged attackers. This is one of the only two helms in the game that give a Cannot Be Frozen bonus. The other is Kira's Guardian, which can only be found on Battle.net's Ladder. The only other possible way to acquire Cannot Be Frozen on a helm is to put a Cham into a socketed helm.
