Duskfeather Wings

The demise of a wave's final monster prompts a loot roll scaled to that enemy's level. In the event of a legendary roll, any equipment slot offering an eligible base has an even chance to be selected—save for Back, which possesses a 7% relative weight—before picking a base uniformly from that slot. Duskfeather Wings requires an extreme enemy level 9999 to enter the loot pool. On Normal, item level falls between 10 × (level − 1) and 10 × level + 9. In Nightmare and Inferno, foes are set to level 70, producing item levels equal to 700 plus the map's level (multiplied by 2 in Inferno).
