Hades 2 begins with players using the Witch’s Staff, but before long, you’ll likely want to explore other options. The good news is that there are several weapons to unlock, each with a unique attack pattern, strengths, and weaknesses.
These weapons can be accessed in the preparation area before you head out into Erebus. To find this prep area, head to the lower-right section of the hub area, past the Cauldron and various NPCs. At the center of this space, you’ll find the Silver Pool—a large circle surrounded by several smaller circles.
Interact with the central circle to open the menu where you can browse different Nocturnal Arms and Gathering Tools. Each weapon comes with its own purchase price, with the early ones requiring Silver to unlock. As you progress through the game and acquire new weapons, additional options will be added to this menu.
This location is also where you will unlock and equip Arcana Cards, collect and upgrade Keepsakes, and eventually improve weapons through Aspect upgrades. Since you’ll pass through the prep area every time you embark on a run, take a moment to make sure your build is tailored to your playstyle before heading out.
