Ambrosia

Ambrosia is one of several Artifact currencies that can be earned within the Underworld. Along with Diamonds and Titan Blood, they are a resource obtained via bounties. It is primarily used as a special gift for those who have deepened bonds with Zagreus. Most characters are eventually able to be gifted Ambrosia. However, there are a few who cannot: Bouldy, Hades, and those unable to be gifted Nectar. A few characters, upon receiving their first Ambrosia from Zagreus, will return the favor with a Companion.

Ambrosia can also be used to increase the effectiveness of a Companion, giving it more uses per escape attempt. In addition, it can be used to purchase two themes - Lovely and Sonorous - from the House Contractor.

A total of 10 Ambrosia can be traded to the Resource Director at various ranks to rank up.
