Shadow Dye

Shadow dye is obtained from hard and elite clue scrolls. All tier 90 armour and weapons can be dyed with it. Once the dye is applied to an item, that item becomes untradeable, and the dye cannot be removed by any means.

Once added to a piece of level 90 equipment, the equipment also becomes repairable, allowing for a one time, albeit expensive, way to permanently keep your level 90 equipment.

In hard clues, shadow dye has a 1/10 chance of being obtained from the dye drop table, which has a 1/96 chance of being accessed from the rare drop table, which in turn has a 1/16 chance of being accessed from the standard table (per drop slot). This means that shadow dye has a 1 in 15,360 chance of being obtained per drop slot - if 5 items are obtained, the probability of getting 1 (or more) shadow dyes is slightly below 1/3072 (~0.03255%).
