99 Nights in the Forest – How to Get the Volcanology Badge (150 Sacrifices)

The Volcanic Biome event has introduced some of the toughest and most time-consuming challenges to 99 Nights in the Forest, but none are more infamous than the Volcanology badge. This monumental task requires players to make a staggering 150 sacrifices to the volcano god, a long and arduous journey that will test your survival skills, your patience, and perhaps even your friendships.

This is not a challenge you can complete in a single sitting. Earning this badge requires a full, dedicated playthrough from the very first day all the way to a demanding late-game farming loop that can take hundreds of in-game days to complete. This guide will provide you with a complete, step-by-step strategy to efficiently conquer this challenge. We’ll break the entire process down into three distinct phases: the early-game rush to find the volcano, the mid-game preparation phase to ensure your survival, and the final, brutal late-game grind to gather your sacrifices.

Phase 1: The Early-Game Rush to Max Map

Before you can make a single sacrifice, you must first reach the volcano. This is the first major hurdle of the challenge, as the new Volcanic Biome is located at the absolute edge of the world map.

The Goal: Finding the Volcano

Your one and only priority in the early game is to fully upgrade your campfire to its maximum level. Each campfire upgrade expands the radius of your revealed map, and you will not be able to see or travel to the Volcanic Biome until you have achieved a “max map.” This means that the first 50-60 days of your run will be a frantic race to gather the necessary resources to fuel and upgrade your fire as quickly as possible.

Early-Game Speedrun Strategy

To maximize your efficiency and unlock the map quickly, you should focus on these key objectives:

1. Rescue the Missing Children: The four missing children scattered around the map should be a top priority. Rescuing them not only provides you with valuable resources and allies but also progresses key questlines that are essential for survival.
2. Gather Wood and Stone Constantly: You will need a massive amount of basic resources, especially wood, to keep your fire fueled and to pay for the increasingly expensive campfire upgrades. Make it a habit to constantly be chopping trees and mining rocks as you explore.
3. Prioritize Campfire Upgrades Above All Else: While it may be tempting to craft better weapons or build elaborate defenses early on, every resource should first be considered for the campfire. Pour everything you have into upgrading it as fast as you can.
4. Establish Basic Food Production: You’ll need to eat to survive. Set up a few basic farm plots early on to ensure you have a steady, if small, supply of food to keep you going as you focus on expanding the map.

Phase 2: Mid-Game Preparation and Gearing Up

Once you have successfully upgraded your campfire to the maximum level and the Volcanic Biome is revealed on your map, your strategic priority shifts. The early-game rush is over, and now you must prepare for the long and dangerous grind ahead. The Volcanic Biome is a high-level zone, and the nightly cultist attacks will become far more intense.

Building a Sustainable Base

Now is the time to turn your simple camp into a fortified, self-sufficient base.

• Mass Food Production: Your small farms won’t be enough for the long haul. Expand your agricultural operations significantly and, most importantly, craft a Crock Pot. Making high-value food like Stew is essential for surviving the late game.
• Essential Defenses: Before you even think about making the long trek to the volcano, you need to secure your base. Craft a Lightning Rod immediately to protect your structures from destructive lightning storms. Begin building a network of walls and traps to help you manage the nightly cultist hordes, which will soon become your primary source of sacrifices.
• Upgrade Your Crafting Bench: Get your Crafting Bench to the maximum level. This will unlock the best weapons, armor, and tools, which are absolutely necessary for surviving in the Volcanic Biome and for efficiently farming cultists.

Gearing Up for the Volcano

The Volcanic Biome is home to dangerous new Scorpion enemies and environmental hazards like lava. You will need to be well-equipped before you venture in. Make sure you have a good ranged weapon like a Rifle or Crossbow, the best armor you can craft, and a healthy supply of healing items like Bandages and Medkits. Don’t forget to bring snowballs to extinguish the fire damage you’ll inevitably take from stepping in lava.

Phase 3: The Late-Game Sacrifice Grind

With a secure base and top-tier gear, you are now ready for the final, grueling phase: gathering and making 150 sacrifices.

What Counts as a Sacrifice?

The volcano god is not picky, but there are rules. You can sacrifice the following:

• Cultist Corpses: This is your main, most reliable source of sacrifices. After defeating cultists, you must pick up their bodies and carry them to the volcano.
• Player Corpses (Your Teammates): In a morbidly hilarious twist, the corpses of your fallen teammates also count as valid sacrifices! If a friend dies, you can carry their body to the volcano for the cause.
• Important Rule: A corpse will only count as a sacrifice if the death was caused by something other than the volcano itself. You cannot simply throw a living player into the lava and then re-sacrifice their body. They must be killed by an enemy or an environmental hazard first.

The Farming Loop: How to Get 150 Bodies

This process is a long grind that can take you past day 200. The most efficient loop is as follows:

1. Hunt Cultists in Strongholds: The best way to get a large number of bodies at once is to find and raid the cultist forts and towers scattered around the map. These locations are packed with enemies.
2. Survive the Nightly Hordes: As the days go on, the nightly attacks on your base will become a fantastic and consistent source of fresh corpses.
3. Haul the Bodies to the Volcano: This is the most time-consuming part. You will need to make many long and dangerous trips from the cultist camps or your base all the way to the volcano, carrying the bodies one by one to be dropped into the lava.

Rewards for Sacrificing

It’s important to manage your expectations. While the volcano does give you loot each time you make a set of sacrifices, the rewards are generally not incredible. You will mostly receive Cultist Gems and the new Gemma of the Forest Fragments. The true reward for this monumental effort is the Volcanology badge and the exclusive Lava Fountain furniture item that comes with it. There is no special cinematic or eruption event upon completion; the badge is the prize.
