Thornheart Cuirass
Chest Armor
Damage dealt by Thorns is increased by 500%, but you lose 15% Max Health.
How it drops
Available starting right at enemy level 1, Thornheart Cuirass is a legendary chest piece open to all classes. Loot rolls occur once at the conclusion of each wave using the final enemy's level. A legendary result gives every slot containing an eligible base an equal shot, save for Back which drops at 7% of that chance, followed by an impartial pick among bases within that slot. Item level spans 10 × (level − 1) to 10 × level + 9 on Normal. For Nightmare and Inferno, enemies are set to level 70, giving an item level of 700 plus the map's level (or × 2 on Inferno).
Possible affixes
Every Legendary piece generates four primary affixes alongside one secondary affix, picked without duplicates from a stat pool that excludes anything unusable by your class; protective gear is also guaranteed to roll Armor as a baseline bonus. The stat intervals listed here reflect the underlying formula tied to item level, which you can experiment with directly using the item roll calculator.
