Adventures of the Seven Dorks
Existing magic items can be decomposed into Residuum dust via the use of the ‘Disenchant Magic Item’ Ritual. This will destroy an item and return an amount of residuum based on the item’s rarity and its standard gold value (not the same as its sale or purchase value). Common items return 20% of their value in residuum, Uncommon items return 50% and Rare items return 100%. So for example an Uncommon 1,000 gold piece item will give you 500 grain of residuum.
Disenchant Magic Item costs 25 g for components per ritual.
