The Glassblower's Breath is a Nightmare Unique relic, hunted from Cinder Wyrm in the Mortal Arena, always at item level 120. It is one of four Exceptional drops on its list — 2.5% of the Uniques that boss gives up, about 1 in 40 — and every kill rolls the list 5 times. It is built on Eternal Weepingglass Relic — step 6 of the Weepingglass Relic line, item level 80 and up.

It always rolls the same numbers: +40 Power, +8% Ultimate Generation, +18% Fire Damage, +25% Ultimate Generation, +48% Fire Damage, +63% Ultimate Generation, +58% Critical Damage and +688 Ward.

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 The Glassblower's Breath — Your Ultimate is attuned to Fire, pulses 6 more times and Burns everything inside it; a full Burn Ignites, but the circle is 20% narrower.

It fires Soul Siphon on its own: Kills charge your Ultimate by 40 points.

It leans into Fire and Burn.

Wearing it hands you Soul Torrent.
