Long Night Plume is a Demon Unique helm with no boss attached: it drops anywhere in Nightmare, most often from N6 up (rarer below that home difficulty, never above it), and nowhere else. Every copy is item level 100, and there 0.3% of what falls comes up Unique. It is built on Sovereign Wardenplume Helm — step 6 of the Wardenplume Helm line, item level 80 and up.

It always rolls the same numbers: +44 Armor, +40 Ward, +327 Maximum Health, +50 Armor, +50 Ward, +187 Armor, +469 Ward and +54% Ultimate Generation.

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 Long Night Plume — +50% Ward; +25 Ultimate Generation.
