How it drops
Eligible to drop once monsters reach level 35, Unyielding Cuirass is a legendary body armor open to all adventurers. Every wave generates one loot roll upon the demise of the last enemy, scaled to that enemy's level. If a legendary drop is awarded, qualifying slots are evenly weighted—aside from the Back slot, which is 7% as likely—and a base item is chosen at random from within that slot. Normal mode item levels range from 10 × (level − 1) to 10 × level + 9, whereas Nightmare and Inferno lock enemy levels to 70, granting an item level of 700 plus map level (doubled 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.
