Duo Boons are a type of Boon which combines the powers of two different gods for a unique effect. Duo Boons can only be obtained with the correct prerequisite boons, and like normal boons, are lost when Zagreus dies and returns to the House of Hades.
There are currently 18 Duo Boons in Hades, shared between 8 different gods: Aphrodite, Ares, Artemis, Athena, Dionysus, Demeter, Poseidon, and Zeus. Hermes and Chaos, though they offer Boons, will never offer Duo Boons. Every god has a minimum of 4 associated Duo boons.
All Duo Boons are classified as "Tier 3 Boons" similar to Legendary Boons. (This means that they require at least 2 other Boons from Tiers 1 or 2 to appear.)
