Why You Need the Infernal Helmet?

The Infernal Helmet isn’t just another cosmetic item – it’s a game-changing piece of equipment that significantly improves your survivability in one of the game’s most challenging biomes. Here’s why this helmet should be a priority in your progression:

Primary Benefits

Lava Attack Immunity: The most crucial feature of the Infernal Helmet is its complete immunity to lava damage from enemy attacks. This means you can explore the Volcanic Biome without constantly worrying about being one-shot by fire-based enemy abilities.

General Damage Reduction: Beyond fire protection, the helmet provides solid base defense stats, slightly reducing all incoming physical and magical damage. This cumulative effect makes it valuable in combat scenarios across all biomes.

Critical Warning

🚨 Environmental Lava Warning: While the helmet protects you from enemy lava attacks, it does NOT make you immune to environmental lava pools. If you fall or jump into a lava pool inside the volcano, you will still take massive tick damage and die. Always treat volcanic terrain with respect and maintain safe positioning.

Infernal Helmet Crafting Recipe & Materials

Crafting the Infernal Helmet requires gathering specific materials and accessing the appropriate crafting station. Here’s your complete crafting breakdown:

Required Materials

Material	Quantity	Farming Location	Farming Strategy
Scorpion Shells	6	Volcanic Biome	Kill Scorpions roaming the biome
Cultist King Antler	1	Cultist King Base	Defeat the Cultist King boss

Crafting Station

Tool Workshop: You must have access to the Tool Workshop to craft the Infernal Helmet. Ensure this station is unlocked and operational in your base before attempting to craft.

Farming Scorpion Shells

Scorpion Shells are relatively straightforward to obtain, making this part of the preparation process manageable for most players:

Location Strategy

Volcanic Biome Roaming Areas: Scorpions can be found roaming the outer edges of the Volcanic Biome. They typically spawn near rock formations and scorpion nests.

Efficient Farming Techniques

Range Combat Advantage: Since Scorpions can deliver painful stings, it’s recommended to engage them from a distance using ranged weapons like rifles or tactical shotguns.

Patrol Routes: Create efficient patrol routes around the perimeter of the Volcanic Biome to maximize Scorpion encounters while minimizing unnecessary risks.

Loot Management: Scorpions have a decent drop rate for their shells, so you shouldn’t need to kill more than 10-15 Scorpions to gather the required 6 shells.

Summoning and Defeating the Cultist King

The real challenge in obtaining the Infernal Helmet lies in defeating the Cultist King. This multi-step process requires preparation, strategy, and execution.

Step 1: Farm Cultist Gems

Location: Cultist Stronghold (near the Volcanic Biome)

Farming Strategy:

Clear out standard cultist enemies efficiently
Use high-DPS weapons for faster farming
Target cultists in groups to maximize gem drops
Be prepared for combat as cultists can be aggressive

Drop Rate Considerations: Cultist Gems can have slightly annoying drop rates, so persistence is key. Bring plenty of healing potions and consider farming in sessions to maintain efficiency.

Step 2: Locate the Cultist King Base

Visual Identification: The Cultist King Base is a massive, highly visible structure within the Volcanic Biome. Look for:

Large ominous architecture
Distinctive red and black color scheme
Four prominent altars inside
Elevated positioning for strategic advantage

Step 3: The Summoning Ritual

Preparation Checklist:

✅ 4 Cultist Gems in inventory
✅ Full health bar
✅ Active buffs
✅ Healing potions ready
✅ Best equipped weapons

Ritual Execution:

Enter the Cultist King Base
Locate the four distinct altars
Place one Cultist Gem on each altar
The boss spawns immediately upon placing the fourth gem

🎮 Pro Tip: The moment you place that fourth gem, the boss spawns immediately. Make sure your health is topped off, your buffs are active, and your hotbar is loaded with healing potions before you interact with the final altar.

Step 4: The Boss Fight

Cultist King Behavior:

Walks toward players in field of vision
Uses Cultist King Mace for melee attacks
Deals heavy area-of-effect (AoE) fire attacks
Has very high HP (highest regular boss in the game)

Combat Strategies:

Range Combat Method:

Immediately run outside and hide behind the doorway entrance
Use ranged weapons like Rifle or Tactical Shotgun
Attack from safety while the boss can’t reach you
This is the safest and most recommended approach

High Ground Advantage:

Retreat to elevated positions like ladders or structures
The Cultist King has simple pathfinding and cannot climb ladders
Shoot repeatedly at his head while maintaining elevation
This exploits his AI limitations effectively

Lava Trapping Method:

Use lava strategically when his HP is low
Finish him off with direct attacks
This method is riskier but can be effective

Key Combat Tips:

Keep moving constantly to avoid telegraphed slams
Burst damage during his recovery windows
Don’t get overconfident – he can kill in 3-4 hits
Watch for his fast walk speed (can catch sprinting players)

Boss Rewards

Upon defeating the Cultist King, you’ll receive:

Mossy Coins (currency)
Cultist King Antler (essential for crafting)
Either: Infernal Sack, Infernal Sword, or Infernal Crossbow

Crafting Your Infernal Helmet

Once you have both the Scorpion Shells and Cultist King Antler in your inventory:

Return to your Tool Workshop
Select the Infernal Helmet from the crafting menu
Confirm the crafting process
Equip your newly crafted Infernal Helmet

Advanced Strategies for Volcanic Biome Survival

Equipment Synergies

Best Weapon Combinations:

Crossbow (lava-resistant) for safety

Armor Recommendations:

Combine with fire-resistant gear when available
Prioritize damage reduction items

Base Building Considerations

Keep spare Cultist Gems for future summonings
Maintain consistent resource flow

Combat Mistakes

Maintain awareness of environmental hazards

Frequently Asked Questions

Does the Infernal Helmet protect you from lava pools in 99 Nights in the Forest?

Answer: No. The Infernal Helmet only provides immunity to lava damage that comes directly from enemy attacks. If you step, fall, or swim in environmental lava pools, you will still take fatal damage. Always be careful around lava terrain even with this helmet equipped.

Where do I find Cultist Gems to summon the Cultist King?

Answer: Cultist Gems are dropped by standard cultist enemies. You can farm these efficiently by clearing out mobs at the Cultist Stronghold located near the Volcanic Biome. The drop rate can be inconsistent, so persistence and efficient farming techniques are recommended.

What crafting station is needed to make the Infernal Helmet?

Answer: You must use the Tool Workshop to craft the Infernal Helmet. Make sure you have 6 Scorpion Shells and 1 Cultist King Antler in your inventory before attempting to craft it. The Tool Workshop is essential for most equipment crafting in the game.

How often can I summon the Cultist King?

Answer: The Cultist King can be summoned once every in-game day, as long as the spawn requirements are met. This means you can defeat him daily if you have the necessary Cultist Gems, allowing for consistent farming of the Cultist King Antler.

What’s the best strategy for defeating the Cultist King?

Answer: The most effective strategy is to use ranged combat from a safe position. Immediately run outside and hide behind the doorway entrance after summoning him, then use weapons like Rifle or Tactical Shotgun to attack from distance. Alternatively, retreat to high ground like ladders where he cannot reach you, then attack repeatedly. Always come prepared with full health and healing potions.

Can the Cultist King drop his mace?

Answer: No, this is a common misconception. The Cultist King Mace is an admin-only, unobtainable item. Despite rumors about a very low drop chance, it cannot be obtained by regular players defeating the boss. The Cultist King drops Mossy Coins, a Cultist King Antler, and either an infernal sack, Infernal Sword, or Infernal Crossbow.

Expert Tips and Advanced Strategies

Farming Optimization

Efficient Scorpion Farming: Create patrol routes that cover multiple Scorpion spawning areas. Focus on the outer edges of the Volcanic Biome where Scorpions are most common. Use ranged weapons to avoid taking damage and maintain a consistent farming pace.

Cultist Gem Farming: Target cultist groups rather than individual enemies. This increases your efficiency and reduces the time spent farming. Consider bringing high-damage weapons to clear groups quickly.

Boss Fight Mastery

Timing and Positioning: Learn the Cultist King’s attack patterns and telegraphs. His slams are heavily telegraphed, giving you time to move. Keep moving constantly to avoid damage and only attack during his recovery windows.

Resource Management: Use healing potions strategically. Don’t wait until your health is critically low to use them. It’s better to heal proactively than to try and recover from dangerous situations.

Long-term Planning

Sustainable Farming: Since you can summon the Cultist King daily, plan your resource gathering around this cycle. Stockpile extra Cultist Gems to ensure you can farm consistently without interruption.

Base Optimization: Set up your base with easy access to both the Volcanic Biome and your Tool Workshop. This reduces travel time and makes the crafting process more efficient.
