The Fairy Biome update introduced a brand-new side area that completely changes how part of your long-term progression works. This is not just another loot zone. It adds a living event built around restoring the Mother Tree, and the rewards permanently upgrade your farming economy.
Here is the full walkthrough from start to finish.
Finding the Fairy Biome
When a new world generates, a small glowing area can appear on the map. This is the Fairy Biome.
Inside, you will find:
At the center of the biome sits the Mother Tree and a locked chest.
Understanding the Mother Tree Event
The Mother Tree starts in a broken state with disconnected root paths spread throughout the biome. The chest near it remains sealed and tells you that the Mother Tree must be restored first.
Your job is to reconnect every broken root segment back to the main tree.
How to Get Acorns
Acorns are required to rebuild the tree.
New wolf enemies roam the Fairy Biome. Kill these wolves to obtain acorns. You will need many of them, so expect to clear multiple wolf spawns.
How the Root System Works
This is the core puzzle.
Scattered across the Fairy Biome are broken root endpoints. When you plant an acorn near one of these endpoints, it extends a new root segment outward.
Your goal is to:
Some roots stretch very far across the biome, even around corners and hidden areas, so explore carefully.
Keep planting acorns until all root lines are physically connected.
Restoring the Mother Tree
Once every root has been linked, the Mother Tree restores itself. You will see it grow back to full size.
At this point, the locked chest becomes accessible.
Mother Tree Rewards
Open the chest to receive:
These rewards are permanent account upgrades.
Using the Farm Recipe Tablet
Take the Farm Recipe Tablet to your crafting bench.
Inserting it unlocks the Enriched Farm Plot craftable structure. This upgraded plot replaces your standard farming plot and improves long-term crop value, making farming more profitable and efficient.
Depending on your crafting tier, you may need bolts and bench upgrades to craft it.
The Fairy Biome is not just cosmetic. Restoring the Mother Tree permanently upgrades your farming progression and resource efficiency.
Once completed, your world gains stronger long-term economic growth, making this one of the most important side quests in 99 Nights in the Forest.
