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:

• 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.

Step-by-Step Guide to Get the Infernal Sack in 2026

Step 1: Locate and Clear the Cultist Base

The Cultist Base is your primary target for obtaining the Infernal Sack. This rare structure contains multiple enemies and valuable loot opportunities.

Cultist Base Details:

• Inhabitants: 4 regular Cultists + 2 Crossbow Cultists
• Structures: 4 buildings including towers with Gold Chests
• Loot Potential: Scrap, Fuel, Healing Items, Weapons, Armor, and most importantly – the Legendary Inferno Chest

Strategy for Clearing:

• Team Up: Cultist bases are extremely difficult to solo
• Priority Targets: Eliminate Crossbow Cultists first (ranged damage)
• Use Cover: Utilize structures for protection from ranged attacks
• Loot Thoroughly: Check all buildings and towers for additional chests

Step 2: Open Legendary Inferno Chests

After clearing the Cultist Base, you’ll gain access to Legendary Inferno Chests, which have the highest drop rate for the Infernal Sack.

Inferno Chest Information:

• Location: Appears after clearing Cultist Base
• Contents: Inferno Sword, Infernal Sack, Wildfire Potion
• Drop Rate: RNG-based, requires multiple attempts
• Appearance: Distinctive fiery chest design

Farming Strategy:

• Repeat Runs: Since loot is RNG-based, complete multiple Cultist Base runs
• Team Efficiency: Form a dedicated farming team for faster clears
• Track Progress: Keep count of runs to estimate drop rates

Step 3: Utilize the Hell Pit for Additional Chances

The Hell Pit provides an alternative farming method with different mechanics.

Hell Pit Mechanics:

• Location: Inside the Cultist Cave in Volcanic Biome
• Function: Sacrifice defeated cultists for random inferno items
• Requirements: Must defeat cultists in the cave first
• Success Rate: Not guaranteed, but provides additional chances

Optimal Hell Pit Strategy:

• Collect Bodies: Gather defeated cultist corpses
• Sacrifice at Hell Pit: Use the pit for chance at inferno items
• Repeat Process: Farm cultists continuously for maximum chances

Step 4: Farm Common Volcano Chests

While less rewarding than Legendary Inferno Chests, Common Volcano Chests still provide opportunities for inferno items.

Common Chest Locations:

• Scattered throughout Volcanic Biome
• Near lava pools and rock formations
• Inside various structures and buildings

Benefits of Common Chests:

• Easier Access: No major combat required
• Consistent Farming: More frequent than legendary chests

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.
