The Infernal Helmet is one of the most powerful pieces of armour in 99 Nights in the Forest. Added in the Volcanic Biome Part 2 Update, this helmet grants lava damage immunity and reduces all incoming damage, making it essential for anyone exploring the fiery volcanic zone. Crafting it takes some effort — you’ll need to farm specific materials and take down a boss, but the payoff is absolutely worth it. Here’s everything you need to know.

| Materials Needed | 6x Scorpion Shells + 1x Cultist King Antler |
| Key Benefit | Lava damage immunity + damage reduction |
| Biome Required | Volcanic Biome (50% spawn chance) |
The Infernal Helmet is only craftable when the Volcanic Biome spawns. This biome has a 50% chance of appearing in your run, replacing the Snow Biome. If you’re unlucky and get the Snow Biome, you’ll need to start a new run. The Volcanic Biome appears as a grey zone on the map.
Scorpion Shells drop from Scorpions in the Volcanic Biome. Here’s what to know about farming them:
To obtain the second ingredient — the Cultist King Antler — you first need to summon and defeat the Cultist King boss. That requires 4 Cultist Gems. Here’s how to get them:
With 4 Cultist Gems in hand, head to the Cultist King Base — a large castle-like structure in the Volcanic Biome. Inside, place one Cultist Gem on each of the four altar pedestals. The Cultist King will spawn immediately and attack.
Combat tips for the Cultist King:
Upon defeat, the Cultist King drops Mossy Coins, the Cultist King Antler (guaranteed), and either an Infernal Sword or Infernal Crossbow.
Head to the Tool Workshop and assemble the Anvil (its parts are spread across the first, second, and third floors). Once assembled, select the Infernal Helmet from the crafting menu and provide:
The helmet will be crafted and ready to equip.
The Infernal Helmet provides two key advantages:
It’s especially powerful when paired with Thorn Body armor, which players have noted creates a near-unstoppable defensive combination in the Volcanic Biome.

The Infernal Helmet grants immunity to lava damage from lava-based attacks and provides a small reduction to all incoming damage. It does not protect against the volcano’s lava pools.
You need 6 Scorpion Shells, dropped by Scorpions in the Volcanic Biome.
The Cultist King drops Mossy Coins, a Cultist King Antler (required for the Infernal Helmet), and either an Infernal Sword or Infernal Crossbow. There’s also a small chance it drops a Cultist Gem.
The Cultist King Base is a large castle-like structure located in the Volcanic Biome. It spawns alongside other biome-specific enemies like Scorpions and Hellephants.
No — the Infernal Helmet is only available when the Volcanic Biome spawns. If you get the Snow Biome instead, you’ll need to start a new run.
