In Hades 2, similar to its predecessor, Melinoe can give gifts to the fellow inhabitants of The Crossroads and the gods they meet on their journey in the Underworld to reach Chronos. A special item called Bath Salts can also be given to some of the NPCs to raise their friendship levels; however, as far as early access goes, it seems you can only give Bath Salts and invite people to the Crossroads Hot Springs if they are staying at the Crossroads themselves.
