Mercy is a Demon Unique dagger with no boss attached: it drops in Adventure Mode once you are level 30 or higher, and keeps dropping there however far you go. Every copy is item level 35, and there 0.8% of what falls comes up Unique. It is built on Stiletto Dagger — step 3 of the Stiletto Dagger line, item level 30 and up.

It always rolls the same numbers: +18 Power, +19% Attack Speed, +3% Melee Lifesteal, +4% Critical Chance, +14% Critical Damage, +5% Critical Chance, +19% Critical Damage and +10% 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 Mercy — Your Main's built-in crit chance is 50% higher. +3% Critical Chance.

Wearing it hands you Fang Flurry.

“It only ever asks once.”
