Solstice Vigil is a Mortal Unique ring, hunted from Frost Wyrm once you are at Threat 20 or higher. It is one of four Exceptional drops on its list — 2.5% of the Uniques that boss gives up, about 1 in 40 — and every kill rolls the list twice. It is built on Immaculate Wintersend Band — step 6 of the Wintersend Band line, item level 80 and up.

It always rolls the same numbers: +15 Power, +23% Chill Effect, +14% Frost Damage, +150% Chill Effect, +140% Frost Damage, +404 Maximum Health and +63% Cooldown Recovery.

On top of that it carries Solstice Vigil — Your Main is attuned to Frost and every hit builds Chill toward Freeze; it winds up 20% faster and Chill clings 20% longer, but hits 10% softer.

It leans into Frost and Chill.

It is Mortal Arena loot.
