Cocytus
UniqueWeaponFrost StaffChill / freeze
Your Chills stack to -40% attack speed; your Freezes last 2s.
How it drops
Cocytus is a unique for the weapon slot, always on a Frost Staff base. Power grade 3 of 5: it falls as often as a standard unique. Uniques fall from the Risings; a floor drop is one only once in 100,000. Inside each tier a grade 5 falls 8× less often than a grade 1. Only one copy of a unique can be worn at a time.
Stats
Uniques roll a fixed set of affixes chosen to serve the power; only the values roll, from the depth the item drops at and its quality. Below is Cocytus exactly as the game rolls it at quality 100, at three depths.
| Quality 100 | d 100 | d 1,000 | d 10,000 |
|---|---|---|---|
| Cold damage | 2,200 | 119,763 | 11,096,388 |
| Cold Damage to Attacks (implicit) | +90 | +4,878 | +451,926 |
| Cold Damage to Attacks | +128 | +6,968 | +645,608 |
| Increased Critical Chance | +36% | +36% | +36% |
| Increased Damage over Time | +18% | +18% | +18% |
| Cold Resistance | +18% | +18% | +18% |
| Item score | 207 | 11,284 | 1,045,542 |
Percent affixes are fixed at a given quality; flat ones grow with depth. Quality runs 50–125% and multiplies every line.
Builds it belongs to
It lives in the Chill / freeze family of uniques, alongside Traitor's Grasp, Glacier Ward, Frost Totem. Stacking uniques from one family is how a mechanic is pushed past what affixes alone allow.
