Tainted Chromatic Orbs, a common drop from Beyond bosses and a rare drop from other Beyond monsters, are a useful tool for situations where Chromatic Orbs won't get the job done. Maybe you want 4 green sockets on
Garb of the Ephemeral, which almost exclusively rolls blue and red sockets.
Tainted Chromes can only be used upon corrupted items.
These Orbs completely ignore the bias toward socket colors that match the item's attribute requirements.
Each socket is rolled independently, with an equal chance for each of the three socket colors. No biases at all, just a straight one in three.
Generally, these should be used mostly on corrupted six-linked chestpieces.
