Halo of Arlyse is a Legendary ring in Diablo III, added in patch 2.1.2. It requires character level 59 to drop, and originally only dropped for Seasonal characters during the Season Two. After the end of Season Two, it drops for normal characters as well. It replaced the Band of Untold Secrets.
It is designed for Wizards, with Ice Armor providing additional damage reduction (up from 12%), and automatically casting Frost Nova (with all runes and enhancements) when the Wizard takes more than 10% of maximum Life in a single hit, or within 1 second (similar to Illusionist passive skill). It works even if damage is absorbed. This Frost Nova ignores and does not reset the cooldown of a regular skill.

Frostsmith Arlyse labored on the glacier for many months, seeking to harness the power of deep winter. In the spring, her tribe found her frozen corpse a short distance from her camp, holding this ring up to the heavens.
