In TFD, Enzo has a peculiar ability that increases the rewards dropped by Encrypted Vaults. Their usual material drop rates are not that great, and youll need a lot of those crafting materials during your leveling. Thats when Enzo comes in. When he opens up a Vault, he increases the amount of materials and other rewards that drop. And that even works for other players.
