A dose of the potion lasts for one hour. While the potion is in effect, for each item that is smithed, there is a 10% chance that a corrupted ore will be put in your inventory. This means that if you make a platebody there is a 10% chance of finding one corrupt ore and an equal chance from making a dagger. It is not 10% per bar. It does not work while smithing protean bars, at Artisans Workshop or while creating cannonballs. This potion does not work with the Superheat Form curse.
