The Anvil of Fates is an Artifact that removes one of your Daedalus Hammer weapon upgrades at random and gives you two new random upgrades. It can be purchased from Charon for 275 in the Temple of Styx. It allows a player to have three Hammer upgrades in a single run, rather than the normal maximum of two. Some upgrades may be mutually exclusive with others, which reduces the randomised pool as the upgrades are granted. As normal, the effects of the upgrades are lost upon Zagreus's death.
More information on how the upgrades affect the weapons can be found on their respective pages:
- The Anvil can grant upgrades that have not been previously selected, thus fulfilling a part of that weapon's list on the Fated List of Minor Prophecies.
- The Anvil cannot be purchased if no hammers have been picked up in a run.
