Improved Shadow Ingot
An Improved Shadow Ingot, a composite of Shadow Ingot pieces. It does not seem to be appropriate for Shadow Weapon Enhance as it has different properties from the Shadow Ingot. It should be brought to the Blacksmith of Mammon.
Not dropped by monsters.
Cannot be spoiled.
The chances are official (x1). On servers with x10, x100 and higher rates, drop and spoil come more often.
