A Brief Mercy is a Demon Unique relic with no boss attached: it drops anywhere in Hell, most often from H3 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 Eternal Sanctuary Relic — step 6 of the Sanctuary Relic line, item level 80 and up.

It always rolls the same numbers: +14% Healing Power, +28 Ward, +18% Healing Power, +36 Ward, +58% Healing Power, +677 Maximum Health and +66% Healing Received.

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 A Brief Mercy — Sanctuary heals 8% of max health per pulse instead of 5% for 2 more allies, but pulses 5 times instead of 8.

It fires Dawn's Eye on its own: Every 5th critical strike sets a Brand worth 60% of the hit.

Wearing it hands you Sanctuary.

“Not long. Long enough.”
