What is the Infernal Sack?
The Infernal Sack, also known as the Automeat Cooking Sack, is one of the most valuable utility items introduced in the Volcanic Biome update. This fiery red sack serves dual purposes that make it essential for serious players:
Contents
Storage Capacity: Holds up to 20 items, making it significantly better than the starting Old Sack (5 items) and comparable to the Giant Sack (25 items)
Auto-Cooking Feature: Automatically converts raw food items (like morsels) into cooked versions, eliminating the need for manual cooking
This combination makes the Infernal Sack particularly valuable during long expeditions in the Volcanic Biome, where resources are scarce and survival depends on efficient food management.
How to Access the Volcanic Biome?
Before you can hunt for the Infernal Sack, you need to reach the Volcanic Biome, which is the third major biome in 99 Nights in the Forest (alongside Forest and Snow biomes). Here's what you need to know:
Team Composition: Bring allies for difficult encounters
Biome Features
Environment: Dark grey surface with limited vegetation, lava pools
Atmosphere: Warm color palette with volcanic elements
Hazards: Lava pools that damage players and destroy most items
New Enemies: Cultists, Crossbow Cultists, Scorpions

FAQ Section
How rare is the Infernal Sack drop rate?
The Infernal Sack has a relatively low drop rate from Legendary Inferno Chests, typically requiring 10-15 successful Cultist Base clears on average. However, this is RNG-based, so some players may get it sooner while others may take longer.
Can I get the Infernal Sack from sources other than Inferno Chests?
While Ruby Chests in the Volcanic Biome can technically drop the Infernal Sack, Legendary Inferno Chests obtained from clearing Cultist Bases have the highest drop rate. The Hell Pit sacrifice method also provides a chance, though it's less reliable.
What's the best class for farming the Infernal Sack?
Big Game Hunter and Support classes are generally considered best for Infernal Sack farming. Big Game Hunter provides increased damage against tough enemies like cultists, while Support offers healing and utility that keeps the team alive during difficult runs.
Do I need a team to get the Infernal Sack?
While technically possible to solo, attempting to get the Infernal Sack without a team is extremely difficult and not recommended. Cultist Bases contain multiple enemies, including Crossbow Cultists that can quickly eliminate solo players. A team of 3-4 players is optimal.
How long does it take to get the Infernal Sack?
For an organized team, each Cultist Base run takes approximately 15-20 minutes. With an average drop rate requiring 10-15 runs, most players can expect to spend 3-5 hours of focused farming to obtain the Infernal Sack.
Can the Infernal Sack be destroyed?
Like other items in the game, the Infernal Sack can be lost if your character dies. However, it won't be destroyed by lava pools, unlike many other items. Store it safely in your base when not in use.
Is the Infernal Sack worth the grind?
Absolutely. The Infernal Sack's combination of 20-item storage and auto-cooking capability makes it one of the most valuable items in the game, especially for extended Volcanic Biome sessions. It significantly improves quality of life and survival chances.
What happens to raw food in the Infernal Sack?
Raw food items (like morsels) stored in the Infernal Sack automatically convert to their cooked versions over time. This eliminates the need for manual cooking and ensures you always have ready-to-eat food available.
Can I trade the Infernal Sack with other players?
Currently, there is no trading system in 99 Nights in the Forest, so the Infernal Sack cannot be traded between players. Each player must obtain their own through the methods described in this guide.
Will the Infernal Sack be available after the Volcanic Biome event?
According to the update log, the Volcanic Biome was initially intended to replace the Snow Biome for two weeks before becoming a permanent random biome. The Infernal Sack and other Volcanic Biome items are expected to remain available permanently.
