In 99 Nights in the Forest, survival is a slow burn where each night tests your will, and every crafting milestone feels earned. The Gem of the Forest stands at the center of the game’s most powerful crafting tier, acting as both a reward and a gateway to late-game dominance.
Whether you’re curious about where to get it, how it works, or what it unlocks, this complete guide breaks it all down based only on verified in-game data and community-tested strategies.
What Is the Gem of the Forest?
The Gem of the Forest is a high-tier material introduced in the Crafting Update, and it is not a standalone item you can pick up directly. Instead, you’ll need to combine four Gem of the Forest Fragments to create one full gem.
🔹 Formula: 4x Gem of the Forest Fragments = 1 Gem of the Forest
This glowing green gem unlocks Crafting Bench Level 5 and is essential to crafting powerful utility items like the Respawn Capsule, Temporal Accelerometer, and Weather Machine.

How to Get Gem of the Forest Fragments?

There are two confirmed methods to obtain Gem of the Forest Fragments:
1. Defeating High-Level Cultists (Post-Day 90)
- Not all Cultists drop fragments.
- Only Cultists that spawn after Day 90 have a chance of dropping Gem of the Forest Fragments.
- These Cultists often appear during night raids as the game enters late stages.
Tip: Survive beyond Day 90 and be well-equipped before engaging. These enemies are far tougher than earlier threats.
2. Clearing Cultist Strongholds
This is the most reliable method to farm Gem Fragments.
How It Works:
- Look for a diamond icon with an exclamation point (!) on your map — this marks the Cultist Stronghold.
- The stronghold has three levels, each more dangerous than the last.
- After defeating Cultists on all floors, you can access a prize room, which usually contains at least one Gem of the Forest Fragment.
Recommended Strategy:
- Bring 2–3 players with mid- to long-range weapons.
- Prepare healing items and strong armor as the deeper levels are unforgiving.
How to Combine Gem of the Forest Fragments?
Combining fragments is intuitive and automatic:
- Simply stack one fragment on top of another in your inventory.
- Once four are stacked, they will fuse into a full Gem of the Forest.
🔸 No crafting station or ritual needed.
🔸 No placement order required.
What Can You Do With the Gem of the Forest?
Once you have the full gem, you can upgrade your Crafting Bench to Level 5, unlocking the most advanced items in the game.

Crafting Bench Level 5 Requirements
- 50 Scrap
- 50 Wood Logs
- 1 Gem of the Forest
Items You Can Craft with a Level 5 Crafting Station
| Item | Materials | Effect |
| Respawn Capsule | 40 Scrap, 40 Wood Logs, 1 Gem | After charging, the next player to die will instantly respawn at the capsule. |
| Temporal Accelerometer | 40 Scrap, 40 Wood Logs, 1 Gem | Skips the next night entirely upon charging. |
| Weather Machine | 40 Scrap, 40 Wood Logs, 1 Gem | Disables rain and thunderstorms for the next 3 in-game days. |
These items are game-changers, especially in multiplayer. They offer security, control over time, and immunity from harsh weather conditions.
Is Obtaining Gem of The Forest Worth the Effort?
Absolutely. While reaching Day 90+ and taking on Cultist Strongholds requires preparation and perseverance, the rewards speak for themselves:
- You gain access to the most powerful support items in the game.
- These tools can save your base, preserve your team, and manipulate the environment in your favor.
Even collecting multiple gems for multiple utilities is worthwhile if you’re aiming for full control over your forest survival experience.
