Astral Mountains Cavern is the snowfield dungeon — **level 38–44** corridors under a **level 42–45** boss chamber. Fire Pals shred the ice types that dominate here, and the reward for braving the cold is twofold: the best refrigeration staff in the game, and chests that start dropping [Gold Keys](https://palworld-db.com/item/TreasureBoxKey03). The other nine caverns live on the [List of All Dungeons](https://palworld-db.com/dungeons).

## The Cold Crew in the Corridors

Expect ice and dark types at level 38–44 — and don't sleep on [Reptyro Cryst](https://palworld-db.com/pal/reptyro-cryst): **Cooling 5** makes it one of the best refrigerator Pals in the game, and here it's just walking the halls. [Polapup](https://palworld-db.com/pal/polapup) and [Whalaska](https://palworld-db.com/pal/whalaska) swim the frigid pools.

| Pal | Elements | Best Work |
| --- | --- | --- |
| [Lunaris](https://palworld-db.com/pal/lunaris) | Neutral | Handiwork |
| [Maraith](https://palworld-db.com/pal/maraith) | Dark | Gathering |
| [Reptyro Cryst](https://palworld-db.com/pal/reptyro-cryst) | Ice, Ground | Mining |
| [Sibelyx](https://palworld-db.com/pal/sibelyx) | Ice | Farming |
| [Tombat](https://palworld-db.com/pal/tombat) | Dark | Mining |
| [Polapup](https://palworld-db.com/pal/polapup) | Ice, Water | Cooling |
| [Whalaska](https://palworld-db.com/pal/whalaska) | Ice, Water | Cooling |

## A Boss Pool Full of Fridge Staff

One of these 19 spawns oversized in the boss room at level 42–45. If your base food keeps rotting, this is your fix: [Wumpo](https://palworld-db.com/pal/wumpo) (Cooling 5) and [Sibelyx](https://palworld-db.com/pal/sibelyx) (Cooling 3, and it makes medicine too) both roll here. Riders get [Suzaku Aqua](https://palworld-db.com/pal/suzaku-aqua) and [Vanwyrm Cryst](https://palworld-db.com/pal/vanwyrm-cryst) as flying options, and [Mammorest Cryst](https://palworld-db.com/pal/mammorest-cryst) is simply a monster.

## Chests Worth Thawing Your Fingers For

| Item | Why It Matters |
| --- | --- |
| [Gold Key](https://palworld-db.com/item/TreasureBoxKey03) | Opens the best locked chests in the game |
| [Training Manual (XL)](https://palworld-db.com/item/ExpBoost_04) | Massive bench EXP in one bite |
| [Hyper Sphere](https://palworld-db.com/item/PalSphere_Tera) | The sphere tier this cavern's bosses deserve |
| [Giga Sphere](https://palworld-db.com/item/PalSphere_Giga) | Workhorse captures |
| [Reinforced Arrow](https://palworld-db.com/item/ReinforcedArrow) | Free Compound Bow ammo |
| [Large Pal Soul](https://palworld-db.com/item/PalUpgradeStone3) | Serious statue upgrades |
| [Reindrix Stew](https://palworld-db.com/item/StewedIceDeer) | Hearty cooked meal drop |
| [Training Manual (L)](https://palworld-db.com/item/ExpBoost_03) | More bench EXP |

| [Gold Coin](https://palworld-db.com/item/Money) | Cold, hard cash |

> **Tip.** Fire hits ice for bonus damage, but a chunk of this roster is Dark — bring one Dragon Pal alongside your fire attacker and nothing in here is a threat. Check both matchups on the [Best Pals Tier List](https://palworld-db.com/tier-list) before you head in.
