The Millstone is a Demon Unique zweihander with no boss attached: it drops anywhere in Hell, most often from H6 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 Sovereign Bedrock Zweihander — step 6 of the Bedrock Zweihander line, item level 80 and up.

It always rolls the same numbers: +114 Power, +20% Stone Damage, +5% Melee Lifesteal, +108 Power, +18% Stone Damage, +42% Melee Damage, +42% Stone 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 The Millstone — Whirlwind flings enemies 2.5 units and applies Crumble, recharging 30% faster, but spins 3 fewer times.

It leans into Crumble.

Wearing it hands you Charged Overhead and Whirlwind.
