Getting Hades 2 G Rock, or Glassrock, relies on you making it through Erebus and Oceanus to reach the Fields of Mourning in the Underworld. It's an annoying material to get, spawning infrequently in a region that has very few encounter locations anyway, but is an important one if you want to unlock every weapon and some Aspects. Here's what you need to know about mining G Rock in Hades 2 and what you can do with it.

Where to get Hades 2 G Rock (Glassrock)

Glassrock is a material in Hades 2 that can be mined in the Fields of Mourning using the Crescent Pick. Look for the sharp, dark outcroppings while running around the Fields in Hades 2 (or let Selene's Reagent Sensing guide you) and hit any you find three times to get three pieces of Glassrock.

Since the Fields of Mourning is the third region of the Underworld you'll have to get past both Hecate and the Hades 2 Scylla boss fight to be in with a chance of getting any Glassrock. It also doesn't help that it's quite a short region, featuring only a few very large locations, so there aren't many opportunities to get Glassrock in Hades 2 even if you make it to the Fields.

As you grow in strength, the journey to the Fields should get easier, but taking Raki (the white raven Hades 2 Familiar) with you will increase your chances of finding Glassrock outcroppings, and he'll even help you mine them quickly.

The first thing you'll probably want G Rock for is either to upgrade the pick or unlock the Skull weapon, but it's got a few other uses, and you'll need some other materials anyway:

  • Upgrading the Crescent Pick to Rank II: 4 Glassrock + 2 Hades 2 Iron
  • Unlocking the Argent Skull Hades 2 weapon: 2 Glassrock + 1 Hades 2 Bronze
  • Unlocking the Sister Blades' Aspect of Artemis: 15 Silver + 1 Glassrock
  • Unlocking the Moonstone Axe's Aspect of Thanatos: 4 Glassrock + 4 Nightshade
