How To Get Obsidiron Hammer?
Step 1: Trigger the Meteor Shower Event
The journey to obtaining the Obsidiron Hammer begins with the Meteor Shower event, which can occur randomly after Day 5 in your survival run. You’ll know the event has started when you see the ominous message “The sky is on fire” appear on your screen. The sky will turn an eerie red color, and meteors will begin crashing down across the map, creating valuable mining opportunities and dangerous new threats.
During my testing across multiple servers, I’ve noticed the Meteor Shower consistently triggered between Days 5-7, though some players report events as late as Day 10. The key is to prepare early by stockpiling healing items, upgrading your tools, and crafting decent armor before the meteors arrive. Check out our 99 Nights in The Forest crafting guide for essential early-game preparations.
Step 2: Locate and Mine Meteor Crash Sites
Once the meteor shower begins, you’ll find impact craters scattered across the map. These sites feature distinctive red crystalline formations surrounding pools of lava. Each crash site becomes a valuable resource node where you can mine three critical materials:
Materials You Can Mine:
- Meteor Shards (Common drop – red crystals)
- Gold Shards (Uncommon drop – yellow crystals)
- Raw Obsidiron Ore (Rare drop – black ore chunks)
Mining these crystals requires at least a basic axe, though I strongly recommend using a Good Axe or better for faster mining speeds. Each crystal formation typically yields 2-4 Meteor Shards, with Gold Shards appearing approximately 30% of the time and Raw Obsidiron Ore dropping roughly 15% of the time based on my extensive testing.
Pro Mining Tips:
- Bring a sack to maximize inventory space
- Mine during daylight to avoid The Deer and other nighttime threats
- Clear Meteor Crabs first before mining to avoid interruptions
- Focus on larger crystal formations for better drop rates
Step 3: Process Raw Obsidiron Into Ingots
Converting Raw Obsidiron Ore into usable Obsidiron Ingots involves a multi-step refinement process that many players find confusing. Here’s the exact sequence you need to follow:
- Drop Raw Obsidiron Ore from height → Creates Broken Obsidiron Ore
- Throw Broken Ore into lava → Creates Scalding Obsidiron Ingot
- Drop Scalding Ingot into water → Creates Obsidiron Ingot
I recommend using the watchtower near your base for the height drop, then utilizing the lava pool at any meteor crash site for the heating process. Finally, the fishing hole or any water source works perfectly for the cooling step. This process must be repeated three times to gather enough ingots for the Obsidiron Chest.
Step 4: Find and Prepare the Meteor Anvil
After the Meteor Shower event, the regular Tool Workshop transforms into the Meteor Anvil, marked by a red anvil icon on your map. This building becomes your crafting hub for all meteor-related items, including the coveted Obsidiron Chest blueprint.
Meteor Anvil Preparation:
- Enemy defenders: 3 Meteor Crabs guard the building
- Required tools: Good Axe or better to break barricades
- Assembly required: Collect and place three anvil parts
- Part locations: First floor (base), second floor (middle), third floor (top)
Before entering, ensure you have weapons capable of dealing with Meteor Crabs efficiently. These enemies have moderate health but can overwhelm unprepared players. I recommend bringing a rifle or spear, along with bandages for healing. For detailed combat strategies, check our 99 Nights Forest Meteor Shower Event Guide.
Step 5: Craft the Obsidiron Chest Blueprint
With all materials gathered and the Meteor Anvil assembled, interact with the anvil to view available recipes. The Obsidiron Chest appears as the final option in the crafting menu, requiring:
Obsidiron Chest Recipe:
- 10× Meteor Shards
- 5× Gold Shards
- 3× Obsidiron Ingots
Place each material on the anvil platform when prompted. The crafting process takes approximately 5 seconds, after which you’ll receive the Obsidiron Chest Blueprint. This blueprint must be taken back to your base, as it can only be placed within your campfire’s build radius.
Step 6: Place and Open the Obsidiron Chest
Return to your base with the Obsidiron Chest Blueprint and place it like any other furniture item. The chest appears as a distinctive black and red container with glowing meteor patterns. Opening it provides one of two possible rewards:
Possible Rewards:
- Obsidiron Hammer (50% chance)
- Obsidiron Chestplate (50% chance)
If you receive the Obsidiron Chestplate on your first attempt, don’t despair! The chest crafting process is repeatable, allowing you to farm materials and craft additional chests until you obtain the hammer. Most players report getting the hammer within 1-3 attempts.
Obsidiron Hammer Stats and Abilities
Damage Statistics
The Obsidiron Hammer delivers exceptional damage output that rivals end-game weapons:
| Stat | Value |
|---|---|
| Base Damage | 85-95 per swing |
| Swing Speed | 1.0 seconds |
| Explosion Damage | 50-60 AoE |
| Explosion Radius | 5-meter radius |

Unique Explosion Mechanic
The Obsidiron Hammer’s signature feature is its charge-based explosion system. A special meter appears above your hunger bar that fills as you:
- Deal damage to enemies (faster charge rate)
- Take damage while wearing Obsidiron armor pieces (slower charge rate)
Once fully charged, your next hammer swing triggers a powerful explosion dealing 50-60 damage to all enemies within a 5-meter radius. This mechanic makes the hammer exceptionally effective against groups of cultists, wolves, and Meteor Crabs.

Brawler Class (Optimal Choice)
- Grants 25% bonus melee damage
- Increases explosion damage proportionally
- Spawns with Brass Knuckles for early survivability
- Cost: 50 Diamonds
Blacksmith Class (Alternative Option)
- Starts with free Hammer tool
- 20% faster crafting speed for materials
- Better resource efficiency
- Cost: 100 Diamonds

2026 Advanced Tips for Obsidiron Hammer Success
Efficient Material Farming Routes
After extensive testing, I’ve developed the optimal farming pattern for gathering Obsidiron Chest materials:
- Scout all crash sites during Day 6-7 when Meteor Crabs are less aggressive
- Create a circular mining route starting from your base
- Mark sites with remaining crystals using the map
- Return with upgraded tools (Chainsaw or Strong Axe) for faster mining
- Use the Teleporter (if crafted) for quick base returns when inventory is full
Combat Strategies with Obsidiron Hammer
Mastering the Obsidiron Hammer requires understanding its strengths and limitations:
Offensive Tactics:
- Build charge meter on weaker enemies before engaging tough opponents
- Time explosions for maximum enemy clustering
- Use terrain to funnel enemies into explosion radius
- Combine with Obsidiron armor for passive charge generation
Defensive Considerations:
- Explosion doesn’t damage you but can destroy nearby structures
- Maintain distance from base walls during charged swings
- Explosion can trigger accidentally if meter is full
- Works underwater but explosion damage is reduced by 50%
Resource Management for Multiple Attempts
Since the Obsidiron Chest has a 50% chance of dropping the hammer, prepare for multiple crafting attempts:
Material Requirements per Chest:
- 10 Meteor Shards (2-3 crash sites)
- 5 Gold Shards (3-4 crash sites)
- 3 Obsidiron Ingots (4-6 Raw Ores needed)
Based on drop rates, expect to mine 5-7 complete crash sites per chest attempt. With efficient farming, you can craft 2-3 chests per meteor shower event.
Troubleshooting Common Issues
“Meteor Shower Won’t Trigger”
If you’ve reached Day 10+ without seeing the event:
- Ensure you’re not in a private server with modified settings
- Check that your game version is updated
- Try progressing further (some players report triggers as late as Day 15)
- Join a different server if the issue persists
“Can’t Find Meteor Anvil”
The Meteor Anvil only appears after the meteor shower begins:
- Look for the red anvil icon on your map
- Check the previous Tool Workshop location
- Ensure you’ve crafted a map for full visibility
- The building may be in unexplored areas
“Obsidiron Refinement Not Working”
Follow this exact sequence without shortcuts:
- Drop ore from minimum 10-block height
- Use fresh lava (not campfire)
- Use natural water sources (not rain)
- Pick up items immediately after each step
Comparing Obsidiron Hammer to Other Weapons
| Weapon | Base Damage | Special Ability | Obtainment Difficulty |

| Morningstar | 75-85 | Armor Piercing | Hard |
| Chainsaw | 60-70 | Tree Destruction | Medium |
| Tactical Shotgun | 100-120 | Ranged Spread | Hard |
| Laser Cannon | 80-90 | Unlimited Ammo | Very Hard (600 Diamonds) |
The Obsidiron Hammer offers the best balance of sustained damage and crowd control, making it superior for base defense and cultist raids.
