The required level is the item level divided by 10, from 1 to 70. A drop of item level 300 or higher comes with 0 to 1 socket at random. Ancient: 10% of its drops from level 70 enemies and chests and of Mystery items bought at player level 70 (9.872% where Black Mist comes first); twice the upgrade gold and sell price. Black Mist: 0.32% x 4 (Solo Self-Found) of those drops on Nightmare and Inferno and of those Mystery items once Nightmare is unlocked; requires level 70, never Ancient, tradable until its first reveal.

Pumpkin King's Chest (Inferno)
2.5% per opened chest and 0.18% as a Black Mist item.
Pumpkin King's Chest (Nightmare)
2% per opened chest and 0.05% as a Black Mist item.
Pumpkin King's Chest (Normal)
1.5% per opened chest.

Drop chances are the game's rules for offline characters; the game server decides the loot of online characters.

Before upgrades, by item level. An enemy of level E drops item level 10 x (E - 1) to 10 x E + 9 on Normal, 700 and higher on Nightmare and Inferno. Each number rolls on its own from 0.85 to 1.15 x its base. An Ancient drop takes the top of every range.

Attribute = 1.6 x item level x its value per item level x the roll. Ranges at item level 700 and 850:

Upgrades

Each upgrade level adds

2 steps of +5%

Cost of each upgrade
3 x (current upgrade level + 1)² x item level gold, x 2 for an Ancient item, and 3 Iron Ore, 2 Gold Ore and 1 Earth Essence x (current upgrade level + 1)². The success chance falls as the upgrade level rises.
