Doorbreakers is a pair of Demon Unique boots with no boss attached: it drops in Adventure Mode once you are level 64 or higher, and keeps dropping there however far you go. Every copy is item level 69, and there 0.6% of what falls comes up Unique. It is built on Masterwork Bulwark Boots — step 5 of the Bulwark Boots line, item level 60 and up.

It always rolls the same numbers: +63 Armor, +228 Maximum Health, +53 Maximum Health, -12% Dash Cooldown, -32% Dash Cooldown, +208 Maximum Health and +14% Attack 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 Doorbreakers — Your Dash hits for 60% of your Main's damage and moves 25% faster.

Wearing it hands you Driving Rush.

“Knock first, they said. These knock last.”
