Arcanum's Void Cleanse:

If successful, this spell will create a progress quest slot dedicated to cleansing the negative effects of an artifact which has been explicitly tainted or corrupted by the Void. This will act as a measured Reforge, changing the downsides of a Void-tainted artifact. The progress needed to cleanse artifacts is the same progress requirement to recover them. The cost, complexity and upkeep of the spell is based on the below table. - Cost 3, Upkeep 1, Average | +1 Progress per session - Cost 4, Upkeep 2, Hard | +2 Progress per session - Cost 5, Upkeep 3, Very Hard | +3 Progress per session Alternatively, this spell may be cast to gain a +2 bonus to a mech-rp which explicitly is about cleansing the Void.
