Warden's Vow is a Demon Unique robe with no boss attached: it drops in Adventure Mode once you are level 6 or higher, and keeps dropping there however far you go. Every copy is item level 11, and there 0.9% of what falls comes up Unique. It is built on Wardweave Robe — step 1 of the Wardweave Robe line, item level 1 and up.

It always rolls the same numbers: +20 Ward, +28 Ward, +10% Healing Received, +31 Maximum Health, +48 Maximum Health, +24 Armor and +8% Affinity Resistance.

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 Warden's Vow — Your Special is a third wider, and a Special that shoves shoves twice as hard.

“Stitched by the last keeper of the Gate, who swore nothing would pass.”
