Duo Boons/Hades II

HadesHades II

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 when you have the prerequisite boons and, like all boons, are lost when Melinoë dies and returns to The Crossroads.

In Hades II there are 29 Duo Boons, shared between 8 different gods: Aphrodite, Apollo, Demeter, Hephaestus, Hera, Hestia, Poseidon, and Zeus. Artemis, Athena, Chaos, Dionysus, Hermes and Selene will not offer Duo Boons. Every god that may have Duo boons shares one with each other god.

All Duo Boons count for the Aether element.

The chance for a Duo Boon is 12%, increased only by a Miniboss Encounter in Tartarus to 20%.
