How to Get the Infernal Helmet in 99 Nights in the Forest

How to Get the Infernal Helmet in 99 Nights in the Forest (February 2026)

Table Of Contents

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.

How to Craft the Infernal Helmet?

Step 1 – Unlock the Volcanic Biome

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.

Step 2 – Farm 6 Scorpion Shells

Scorpion Shells drop from Scorpions in the Volcanic Biome. Here’s what to know about farming them:

  • Scorpions have roughly 50 HP and deal 20 base damage per hit, plus poison damage over time
  • They patrol the volcanic area and aren’t hard to find
  • Six shells is a relatively light grind — a few Scorpion kills should get you there
  • Tip: Bring a ranged weapon to kill Scorpions safely and avoid the poison

Step 3 – Get 4 Cultist Gems

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:

  • Kill Cultists during nighttime raids on your campfire (most reliable source)
  • Loot Cultist Strongholds across the map (marked by a blue diamond icon)
  • Search the Cultist Laboratory and open Gold Chests
  • There’s also a rare chance to get them from fishing

Step 4 – Summon and Defeat the Cultist King

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:

  • He has an estimated 1,000 HP — this is a tough fight
  • He only deals melee damage, so stay at range and use a Rifle, Tactical Shotgun, or Crossbow
  • Use the pillars and entrance doorway as cover to break his line of sight
  • Luring him near lava deals extra environmental damage
  • Bring friends — co-op makes this significantly easier
  • Fight during the day to avoid the Ram monster complicating things

Upon defeat, the Cultist King drops Mossy Coins, the Cultist King Antler (guaranteed), and either an Infernal Sword or Infernal Crossbow.

Step 5 – Craft at the Tool Workshop

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:

  • 6x Scorpion Shells
  • 1x Cultist King Antler

The helmet will be crafted and ready to equip.

Infernal Helmet Stats & Benefits

The Infernal Helmet provides two key advantages:

  • Lava damage immunity — you won’t take damage from lava-based attacks (note: this does not include the lava pools inside the volcano itself)
  • Damage reduction — reduces all incoming damage by a small amount

It’s especially powerful when paired with Thorn Body armor, which players have noted creates a near-unstoppable defensive combination in the Volcanic Biome.

Pro Tips

  • Don’t select your craft early — only choose the Infernal Helmet in the Tool Workshop once all materials are already in your inventory, since you can’t switch crafts mid-process
  • Pair it with fire-resistant gear for maximum lava zone survivability
  • Bring tamed animals (wolves, bears) to the Cultist King fight as distractions
