Blood Artisan's Cuirass is a Unique Chest Armor. It can only be used by Necromancers.
The Blood Artisan's Cuirass is a unique and revamped armor piece designed for those who harness the power of 
Bone Spirit s and Blood Orbs in their build. What makes this item special is its ability to significantly enhance damage output after collecting Blood Orbs, with a 135% damage increase for four seconds, alongside restoring 12 Essence per orb. The armor also spawns free 
Bone Spirit s when collecting three or more Blood Orbs, with damage scaling based on your life percentage at the time of activation. Although lacking defensive attributes, its potential for overwhelming 
Bone Spirit  spam and synergy with corpse-based skills makes it a compelling choice for offensive-focused Necromancer builds. The armor’s gruesome aesthetic, featuring exposed bones and a grotesque appearance, adds a distinctive flair to any character.Effect
When you pick up [3 - 10] Blood Orbs, a free 
Bone Spirit  is spawned, dealing bonus damage based on your current Life percent.How to get Blood Artisan's Cuirass
