Hostmantle is a piece of Demon Unique armor with no boss attached: it drops anywhere in Nightmare, most often from N10 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 Spiritweave Robe — step 6 of the Spiritweave Robe line, item level 80 and up.

It always rolls the same numbers: +180 Ward, +436 Maximum Health, +110 Ward, +100 Magic Defense, +658 Ward, +42% Summon Damage and +45% Spell 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 Hostmantle — Ultimate damage +25%; +15% Ward.
