What to know
- Tannin is crafted from Divi Divi tree bark found in the Foothills (second biome)
- You need an Alchemy Table to process Tannin
- Recipe requires Clay Bottle x1 and Tree Bark x2
- Main use is crafting potion bottles and reagent-based items
Once you reach the second biome in Windrose, Tannin becomes one of the most important materials for progressing your crafting system. It bridges basic gathering and more advanced alchemy, especially if you want to start producing potions and utility items.
Here is a quick overview of Tannin in Windrose:
| Aspect | Details |
|---|---|
| Resource Type | Alchemy Material |
| Biome | Second Biome (Foothills) |
| Source | Divi Divi Trees |
| Crafting Station | Alchemy Table |
| Recipe | Clay Bottle x1, Tree Bark x2 |
| Primary Use | Potion Bottles & Reagents |
Windrose Tree Bark farming location – Divi Divi Trees
You’ll find Tannin’s core material—tree bark—by harvesting Divi Divi trees scattered across the Foothills biome. This is the second major region in Windrose, and it introduces more structured resource farming compared to earlier zones.

Divi Divi trees are visually distinct, often darker and slightly twisted compared to regular trees, making them easier to identify once you know what to look for. These trees tend to spawn in clusters, which makes farming routes efficient if you plan your movement.

The biome itself is moderately dangerous, so you should clear nearby enemies before gathering to avoid interruptions. Farming becomes much smoother once you establish a safe loop between tree clusters.
How to unlock and craft using the alchemy table

To start crafting Tannin, you must first unlock and place an Alchemy Table. This station is separate from your basic crafting setup and focuses on reagents and potion-related materials.
| Requirement | Amount |
|---|---|
| Clay Pot | 2 |
| Wood | 5 |
Once built, the Alchemy Table allows you to process raw materials like bark into refined resources such as Tannin. Without it, you won’t be able to access the recipe at all.
How to get Tannin in Windrose
Step 1
Gather enough tree bark from Divi Divi trees in the Foothills biome. This is your primary ingredient and the most time-consuming part.

Step 2
Craft or collect Clay Bottles before heading to the Alchemy Table. These act as containers required in the recipe.

Step 3
Interact with the Alchemy Table and navigate to the Tannin recipe in the crafting menu. Ensure your station meets the required level.

Step 4
Insert the materials: Clay Bottle x1 and Tree Bark x2. Double-check quantities to avoid crafting errors. Start crafting and collect your Tannin once the process completes. You can queue multiple crafts if you have enough materials.
Understanding what Tannin is used for in Windrose
Tannin serves as a foundational reagent in the alchemy system, primarily used to craft potion bottles and similar consumable-related items. This makes it essential for both combat preparation and exploration.

As you progress, you’ll notice that many advanced crafting recipes rely on Tannin as a treated material, especially those involving liquids or preserved resources. Its role mirrors real-world tannin usage in treating materials, giving it a consistent in-game logic.
Tannin usage breakdown
| Use | Description |
|---|---|
| Potion Bottles | Core ingredient for crafting potion containers |
| Reagents | Used in multiple alchemy recipes |
| Crafting Progression | Unlocks mid-tier alchemy options |
If you plan to invest in potion crafting, maintaining a steady supply of Tannin becomes non-negotiable.
Efficient farming strategies for Tannin
To farm Tannin efficiently, you should focus on creating a loop route through dense Divi Divi tree areas in the Foothills. This minimizes downtime and maximizes bark collection.

Combining gathering runs with combat clearing ensures uninterrupted harvesting, which significantly improves your overall efficiency. You don’t want to restart harvesting animations repeatedly due to enemy attacks.
It’s also smart to stockpile Clay Bottles in advance, so you can immediately convert bark into Tannin without extra preparation steps. This keeps your crafting flow smooth and uninterrupted.
Tannin is one of those resources that quietly powers your entire alchemy progression in Windrose. Once you understand where to find Divi Divi trees, how to set up your Alchemy Table, and how to manage materials, farming it becomes routine.
By building efficient routes and preparing your crafting materials ahead of time, you can maintain a constant supply and stay ahead in gear and potion progression.
