While Hades 2 brings back several mechanics from the original game, there are several key elements that are either completely new, or revamped and updated. The original Hades had the Mirror of Night and the House Contractor, locations where the bulk of the game's important customization and upgrades were accomplished. Hades 2 introduces entirely new locations for these mechanics, though it stays true to the spirit of the original. Here, Melino now utilizes the Cauldron to unlock many of the same types of items and upgrades. This uses a new mechanic known as Incantations.
