The Quiet Crown is a Demon Unique helm with no boss attached: it drops in Adventure Mode once you are level 24 or higher, and keeps dropping there however far you go. Every copy is item level 29, and there 0.8% of what falls comes up Unique. It is built on Worn Spiritcowl Helm — step 2 of the Spiritcowl Helm line, item level 15 and up.

It always rolls the same numbers: +26 Ward, +71 Maximum Health, +15% Cooldown Recovery, +12% Ultimate Generation, +10% Cooldown Recovery, +121 Ward and +103 Maximum Health.

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 The Quiet Crown — +25% Cooldown Recovery. +16% Ultimate Generation.

“It weighs nothing. That is the trick of it.”
