Aurora Fan is a Demon Unique staff with no boss attached: it drops anywhere in Hell, most often from H7 up (rarer below that home difficulty, never above it), and nowhere else. Every copy is item level 110, and there 0.2% of what falls comes up Unique. It is built on Perfect Auroralens Staff — step 6 of the Auroralens Staff line, item level 80 and up.

It always rolls the same numbers: +132 Power, +20% Frost Damage, +120 Power, +15% Frost Damage, +42% Spell Damage, +42% Frost Damage and +34% Cooldown Recovery.

One Unique drop in 40 is a Mythical copy: the same item carrying 15–25% Mythical Energy that boosts every stat on it and can never be changed; the 15% floor is 10 times as common as the perfect 25%.

On top of that it carries Aurora Fan — Aether Beam is twice as wide and applies Chill, but reaches 35% less far.

It leans into Chill.

Wearing it hands you Aether Beam and Overload.

“Less a beam than a weather.”
