One of the more basic resources you can find early in your first few runs of Hades 2 is Moly. It's an item you'll need to find to craft many of your starting spells, but you should expect to use it for a variety of other recipes later on.
7 Things You MUST Know | Hades 2
You won’t be able to find Moly everywhere. Instead, it will only appear in a certain location, so you’re better off focusing on grabbing as much as possible during a specific run. You’ll always travel a different distance in Hades 2, but grabbing the right ingredients can bring you one step closer to completing one of your many objectives.
The only way to track down Moly is to find it in Erebus. This is the first region of Hades 2 that you can explore, and it doesn’t require any specific tools to collect them, such as the Crescent Pick that you use to collect Silver or the Silver Spade for Nightshade seeds.
You should find Moly scattered around the ground or edges of each Erebus map. I recommend grabbing it once you’ve cleared the area. Enemies will try to attack you in Hades 2 if you’re trying to collect resources from the ground during a fight. As long as you grab it before moving on to the next area, you won’t miss it.
