The Obsidiron Hammer is obtained by opening the Obsidiron Chest in 99 Nights in the Forest. This powerful melee weapon drops randomly from the chest, which must be crafted at the Meteor Anvil using 10 Meteor Shards, 5 Gold Shards, and 3 Obsidiron Ingots after surviving the Meteor Shower event (available from Day 5 onward).

The Meteor Shower update has completely transformed 99 Nights in the Forest, introducing one of the most devastating weapons in the game. I've spent countless hours farming this hammer across multiple runs, and I'm here to share everything you need to know about obtaining this game-changing weapon. Whether you're a solo survivor or running with a full squad, the Obsidiron Hammer will revolutionize your combat strategy against Meteor Crabs, Cultists, and even The Deer itself.

Before we dive into the farming guide, let's talk about why this weapon is worth the grind. The Obsidiron Hammer isn't just another melee weapon—it's a complete game-changer that combines high single-target damage with devastating area-of-effect explosions.
The hammer features a unique explosion mechanic that sets it apart from every other weapon in the game. Above your hunger meter, you'll notice a special explosion bar that fills as you deal damage or take damage while wearing Obsidiron armor pieces (Obsidiron Chestplate and Obsidiron Boots). Once this bar fills completely, the hammer triggers a massive explosion dealing 50-60 damage to all enemies within range.
The base swing speed matches the Morningstar at one second per swing, making it incredibly fast for a heavy weapon. This combination of speed and power makes it perfect for both boss encounters and crowd control situations. When fighting groups of Meteor Crabs or defending your camp from Cultist raids, the explosive AoE damage can clear entire waves in seconds.
The journey to obtaining the Obsidiron Hammer begins with understanding the Meteor Shower event mechanics. This limited-time event is your gateway to all meteor-related content, including the hammer itself.
When Does the Meteor Shower Occur?
The Meteor Shower event can trigger any time from Day 5 onward in your run. There's no guaranteed day it will happen, but most players report seeing their first meteor shower between Days 5-7. The event announces itself with a dramatic message: "The sky is on fire."
When this message appears, the entire sky shifts to a deep crimson red, and glowing meteor trails streak across the horizon. These trails mark the incoming impact sites—pay close attention to where they land, as you'll need to locate these crash sites to gather materials.
The meteor crash sites remain on the map until you mine them completely, so don't panic if you miss the initial impacts. You can search for them during daylight hours when visibility is better. These crash sites feature distinctive characteristics: a central pool of bubbling lava surrounded by tall, spiked red and black rocky formations that can be mined.
To craft the Obsidiron Chest (which has a chance to drop the hammer), you'll need to collect three different types of materials. Each requires different farming strategies and time investment.
Meteor Shards are the most common material you'll need. These glowing red crystals drop frequently from mining the rocky formations at meteor crash sites. Use any axe to break these formations—even your starting axe works, though upgraded axes like the Good Axe or Chainsaw make the process significantly faster.
Pro tip: Meteor Crabs that spawn at crash sites also drop small quantities of Meteor Shards when defeated. If you're confident in your combat abilities, farming these crabs can supplement your mining efforts while also providing combat experience.
Gold Shards share the same mining locations as Meteor Shards but drop at a considerably lower rate. Expect to spend extra time mining to gather all five required shards. The drop rate appears to be approximately 1 Gold Shard for every 3-4 Meteor Shards, so patience is key.
Focus your mining on the larger, more prominent rock formations at crash sites—these seem to have slightly better drop rates for Gold Shards based on community testing. Bring friends if possible, as multiple players can mine simultaneously and share resources.
This is where things get interesting. Obsidiron Ingots require a multi-step refinement process that takes the raw ore through several transformations. Here's the complete step-by-step process:
Step 1: Mine Raw Obsidiron Ore
While mining at meteor crash sites, you'll occasionally discover Raw Obsidiron Ore mixed in with the Meteor and Gold Shards. This material has the lowest drop rate of the three, so expect to do significant mining. The raw ore appears as distinctive black crystals within the rock formations.
Step 2: Break the Ore
Take your Raw Obsidiron Ore to a high location—watchtowers work perfectly for this. Drop the ore from a significant height, and it will shatter upon impact, transforming into Broken Obsidiron Ore. The ore must fall far enough to generate the breaking physics, so make sure you're dropping from at least a two-story height.
Step 3: Smelt in Lava
Pick up the Broken Obsidiron Ore and take it to any lava source. The meteor crash site pools work perfectly for this step. Drop the broken ore directly into the lava, and it will transform into Scalding Obsidiron Ingot. Be careful not to walk into the lava yourself—the damage is considerable and can quickly kill you if you're not at full health.
Step 4: Cool in Water
For the final transformation, take your Scalding Obsidiron Ingot to any water source. The fishing hole near most spawn locations works great, but any body of water will suffice. Drop the scalding ingot into the water, and it instantly cools into a regular Obsidiron Ingot ready for crafting.
Repeat this entire process three times to gather all required ingots for the Obsidiron Chest.
Once you've gathered all materials, it's time to craft the Obsidiron Chest at the Meteor Anvil. This special crafting station only appears after the Meteor Shower event and requires some preparation before you can use it.
Finding the Meteor Anvil
After the Meteor Shower occurs, check your map for a new red anvil icon. This marks the Meteor Anvil building location—it's impossible to miss once you know what to look for. The building resembles a large stone fortress and is a transformed version of the regular Tool Workshop.
When you approach the building, prepare for combat. The Meteor Anvil area is heavily guarded by Meteor Crabs—aggressive enemies that spawn specifically to protect this location. Bring weapons, healing items, and ideally teammates to help clear the area. These crabs hit hard and can quickly overwhelm solo players.
Assembling the Meteor Anvil
Once you've cleared all Meteor Crabs from the building, you'll need to assemble the anvil itself. The anvil comes in three pieces scattered throughout the building:
Pick up each piece and drag it to the highlighted assembly area in the center of the first floor. Once all three pieces are in place, the anvil activates and displays available crafting recipes.
With the Meteor Anvil assembled and your materials ready, it's time to craft the Obsidiron Chest.
Crafting Process:
Important Note: The Obsidiron Chest Blueprint is portable. You don't open the chest at the Meteor Anvil—you must take the blueprint back to your campfire base to place and open it safely.
Transport your Obsidiron Chest Blueprint back to your base within campfire range. This ensures you're in a safe, controlled environment when the chest spawns its loot.
Chest Opening Steps:
RNG and Drop Rates:
Here's the crucial part: the Obsidiron Hammer is not a guaranteed drop. The chest contains randomized loot, and the hammer is one of several possible rewards. Based on community data and my personal experience across multiple runs, the drop rate appears to be approximately 30-40%.
This means you might get lucky on your first chest, or you might need to craft multiple chests before obtaining the hammer. Don't get discouraged—the materials become easier to farm once you understand the systems, and each chest attempt also provides other valuable loot even if you don't get the hammer.
Once you finally obtain the Obsidiron Hammer, understanding how to maximize its potential is crucial for getting the most value from your hard work.
Building the Explosion Meter:
The explosion mechanic is what elevates this hammer from good to exceptional. The meter fills through two primary methods:
This creates interesting tactical decisions. Do you play aggressively to charge the meter through attacks, or do you allow yourself to take controlled damage to build charge faster? Experienced players often use a hybrid approach, tanking hits intentionally while dealing consistent damage.
Optimal Combat Situations:
The Obsidiron Hammer excels in specific scenarios:
Meteor Crab Farming: The fast swing speed combined with explosive AoE makes this weapon perfect for farming Meteor Crabs. Position yourself in the center of a group, build your explosion meter, then unleash devastating chain explosions that clear multiple crabs simultaneously.
Cultist Base Raids: When attacking Cultist strongholds, the hammer's explosions provide excellent crowd control. The AoE damage affects all nearby cultists, making it easier to fight multiple enemies at once without getting overwhelmed.
Defensive Scenarios: During night defense at your campfire, the explosion radius creates a protective zone around you. Enemies approaching your base take massive damage when the explosion triggers, helping protect your critical structures.
Class Synergies:
Certain classes pair exceptionally well with the Obsidiron Hammer:
After crafting your first Obsidiron Chest, you might want to continue farming for additional attempts or to help teammates obtain their hammers. Here are advanced strategies to streamline the process:
While the Obsidiron Hammer is the prize most players seek, the chest can drop other valuable items worth knowing about:
Even "failed" chest openings often provide valuable loot that helps your overall progression, so every craft has value regardless of whether you get the hammer.
Through extensive testing and community feedback, here are the most common errors players make when farming for the Obsidiron Hammer:

Q: The Meteor Shower hasn't appeared by Day 10. What's wrong?
Meteor Showers are RNG-based but should appear between Days 5-10 in most runs. If you've passed Day 10 without seeing one, try continuing your run—the event can still trigger later. Some players report seeing their first shower as late as Day 15.
Q: I can't find the Meteor Anvil icon on my map.
The anvil icon only appears AFTER the Meteor Shower event completes. Make sure you've survived until the next day cycle. If it still doesn't appear, the crash site might be in an unexplored area—venture further from your base to reveal more of the map.
Q: My Obsidiron Ingot disappeared during crafting.
This can happen if you drop it improperly or if it glitches into terrain. Always ensure you're standing on flat, solid ground when performing the refinement steps. If an ingot is lost, unfortunately you'll need to farm another Raw Obsidiron Ore and repeat the process.
Q: Can I trade the Obsidiron Hammer with other players?
Yes! Items can be dropped and picked up by other players within the same server. Many players use Discord to organize trading sessions. However, be cautious and only trade with trusted community members to avoid scams.
The Meteor Shower update is relatively recent (released September 27, 2025), and the developers continue to support the game with regular content updates. Keep an eye out for:
Follow the game's official channels and bookmark this guide—I'll update it whenever significant changes occur.
The Obsidiron Hammer has approximately a 30-40% drop rate from the Obsidiron Chest based on community testing. This means you may need to craft multiple chests (2-3 on average) before obtaining the hammer. The RNG nature makes it one of the rarer weapons in the game.
No, the Obsidiron Hammer requires materials from the Meteor Shower event, which only triggers from Day 5 onward. The earliest possible acquisition would be around Day 6-7, assuming you get the Meteor Shower on Day 5 and immediately farm all necessary materials.
The Scavenger class is ideal for farming due to its expanded inventory space, allowing you to carry more materials per trip. The Brawler class is excellent for combat against Meteor Crabs. Alternatively, the Blacksmith class can speed up crafting times at the Meteor Anvil.
You can craft the Obsidiron Chest unlimited times as long as you have the required materials. Each Meteor Shower event provides renewable resources at crash sites, allowing multiple crafting attempts within a single run or across different runs.
Yes, the Obsidiron Hammer can damage The Deer, though The Deer cannot be killed. The hammer's explosive damage is particularly effective for stunning The Deer and creating space to escape. However, don't expect to defeat The Deer permanently—focus on using the hammer for crowd control and defensive situations.
Yes! Meteor crash sites remain on the map after the Meteor Shower event ends. You can continue mining them for Meteor Shards, Gold Shards, and Raw Obsidiron Ore indefinitely until you completely deplete all resources at the crash sites.
If you die, you'll drop the Obsidiron Hammer where you died. You have a limited time to return and retrieve it before it despawns. Always mark your death location and prioritize recovering the hammer quickly, especially if you died far from your base.
The Obsidiron Hammer has the same swing speed as the Morningstar (1 second per swing) but deals higher base damage plus the additional explosive AoE damage. This makes it objectively superior to the Morningstar in almost every combat scenario, especially against groups of enemies.
Obtaining the Obsidiron Hammer represents one of the most rewarding grinds in 99 Nights in the Forest. Yes, the RNG element can be frustrating, but the explosive power of this weapon makes every failed chest opening worth it when you finally see that hammer materialize.
My recommendation: approach this farm with patience and teammates. Solo grinding is possible but significantly more tedious. Use downtime between Meteor Shower events to progress other aspects of the game—rescue children, unlock badges, experiment with different classes.
Most importantly, don't let the RNG aspect discourage you. Every chest opening is valuable loot, every farming session makes you better at the game's mechanics, and eventually, that Obsidiron Hammer will be yours. When it finally drops, you'll understand why it's considered one of the best weapons in 99 Nights in the Forest.
Good luck out there, survivors. May your meteor showers be plentiful and your RNG blessed. See you in the forest!
