Stolen Sky is a pair of Demon Unique boots with no boss attached: it drops anywhere in Nightmare, most often from N1 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 Exalted Skybound Boots — step 6 of the Skybound Boots line, item level 80 and up.

It always rolls the same numbers: +8% Move Speed, +5% Critical Chance, +327 Maximum Health, +9% Movement Speed, -15% Dash Cooldown, +15% Movement Speed, -42% Dash Cooldown and +46% Projectile Speed.

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 Stolen Sky — Your Dash carries 10% further and moves 20% faster.

Wearing it hands you Vault.
