The Unbroken Sentence is a Demon Unique staff with no boss attached: it drops anywhere in Hell, most often from H4 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 Conduit Staff — step 6 of the Conduit Staff line, item level 80 and up.

It always rolls the same numbers: +120 Power, +14% Cooldown Recovery, +32 Power, +19% Holy Damage, +12% Power, +29% Attack Speed, +42% Holy Damage and +52% Critical Damage.

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 Unbroken Sentence — Your Main deals 35% more damage, pierces 2 more enemies and starts 25% faster.

Wearing it hands you Aether Beam and Overload.

“It began before you picked it up. It will not stop when you set it down.”
