Confirmed Cauldron Recipes
The cauldron matters because it creates high-value jewelry and a key magic item from specific ingredient combinations. This page gives you the confirmed recipes available in the supplied sources, so you can build toward the exact inputs instead of testing blindly.
The Cauldron is categorized as an Automated Processing device. The available device listing identifies three jewelry recipes and one magic recipe. Each recipe uses three inputs and produces one output.
| Output | Input 1 | Input 2 | Input 3 | Time |
|---|---|---|---|---|
| Ruby | Diamond | Pure Gold Dust | Resonant Catalyst | 30.9s |
| Sapphire | Perfect Diamond | World Tree Core | Unstable Catalyst | 38.2s |
| Emerald | Moonlit Soap | Lapis Lazuli | Fertile Catalyst | 45.5s |
| Philosopher's Stone | Ruby | Sapphire | Emerald | 60s |
The three gem recipes are the direct route to the Philosopher's Stone recipe. In practical terms, that makes Ruby, Sapphire, and Emerald the immediate materials to prepare before attempting the magic output.
The supplied device page is a confirmed reference, but it is not presented as an exhaustive list of every possible Cauldron result. For additional combinations, the Codex directs players to the Cauldron Calculator.
Jewelry Recipe Details
Each confirmed jewelry recipe has a different catalyst or specialized ingredient requirement. Check the names carefully before loading the Cauldron, particularly where similar item names appear in the broader item list.
| Recipe | Inputs | Output | Crafting Time |
|---|---|---|---|
| Ruby | 1 Diamond, 1 Pure Gold Dust, 1 Resonant Catalyst | 1 Ruby | 30.9s |
| Sapphire | 1 Perfect Diamond, 1 World Tree Core, 1 Unstable Catalyst | 1 Sapphire | 38.2s |
| Emerald | 1 Moonlit Soap, 1 Lapis Lazuli, 1 Fertile Catalyst | 1 Emerald | 45.5s |
Ruby is the fastest of the three listed jewelry recipes. Sapphire takes longer, while Emerald has the longest listed jewelry processing time.
| Jewelry Output | Listed Time | Difference From Ruby |
|---|---|---|
| Ruby | 30.9s | 0s |
| Sapphire | 38.2s | 7.3s |
| Emerald | 45.5s | 14.6s |
The ingredient requirements do not overlap completely:
- Ruby requires Diamond, Pure Gold Dust, and Resonant Catalyst.
- Sapphire requires Perfect Diamond, World Tree Core, and Unstable Catalyst.
- Emerald requires Moonlit Soap, Lapis Lazuli, and Fertile Catalyst.
That distinction is useful when planning production. A Ruby recipe does not call for a Perfect Diamond, and the Sapphire recipe does not use the Diamond named in the Ruby recipe. Likewise, Fertile Catalyst belongs to the Emerald recipe in the confirmed Cauldron list, while Unstable Catalyst belongs to Sapphire.
These exact names matter when comparing available inventory to a recipe. The sources confirm each three-item combination and its output, but they do not provide substitute inputs for these recipes. Treat each listed combination as a separate recipe rather than a flexible ingredient group.
Philosopher's Stone Recipe
The only listed magic recipe for the Cauldron produces a Philosopher's Stone. It requires one of each confirmed Cauldron jewelry output.
| Required Item | Quantity |
|---|---|
| Ruby | 1 |
| Sapphire | 1 |
| Emerald | 1 |
| Philosopher's Stone output | 1 |
| Crafting time | 60s |
This recipe gives the Cauldron list a clear dependency chain:
- Create a Ruby with Diamond, Pure Gold Dust, and Resonant Catalyst.
- Create a Sapphire with Perfect Diamond, World Tree Core, and Unstable Catalyst.
- Create an Emerald with Moonlit Soap, Lapis Lazuli, and Fertile Catalyst.
- Combine the Ruby, Sapphire, and Emerald for one Philosopher's Stone.
The listed times for the three prerequisite gems add to 114.6 seconds. Including the 60-second Philosopher's Stone recipe, the listed Cauldron processing time for one complete set is 174.6 seconds, before accounting for obtaining the ingredients.
| Stage | Output | Listed Time |
|---|---|---|
| 1 | Ruby | 30.9s |
| 2 | Sapphire | 38.2s |
| 3 | Emerald | 45.5s |
| 4 | Philosopher's Stone | 60s |
| Total | One complete Philosopher's Stone set | 174.6s |
The total above is a sum of the processing times displayed for the individual recipes. It is not a source-provided estimate for a whole factory line, and it does not include the time needed to acquire or prepare any inputs.
Using the Cauldron Calculator
The Codex directs players seeking the full Cauldron recipe list to the Cauldron Calculator. Its input interface provides three item selections, with the third input marked optional. The item selection list includes values for many items, including several relevant materials.
| Item | Listed Value |
|---|---|
| Unstable Catalyst | 746 |
| Fertile Catalyst | Not shown in the supplied calculator excerpt |
| Ruby | Not shown in the supplied calculator excerpt |
| Sapphire | Not shown in the supplied calculator excerpt |
| Emerald | Not shown in the supplied calculator excerpt |
| Blast Potion | 1,197 |
| Meteorite | 800 |
| Diamond | Not shown in the supplied calculator excerpt |
The calculator is especially helpful because Cauldron combinations are not presented like ordinary device recipes. A Steam discussion describes the system as having a unique recipe for every ingredient combination, potentially resulting in thousands of recipes. Another player response recommends entering different items into the Codex calculator to see what they produce.
The calculator interface supports a first input, second input, and optional third input. That makes it useful for checking combinations when a player has candidate materials but does not yet know the output. The supplied excerpt confirms the interface and item-value list, but it does not show results for every possible combination.
For the four confirmed recipes on this page, use the exact three-item combinations shown above. Do not substitute an item simply because it sounds related. The documented recipes distinguish between Diamond and Perfect Diamond, as well as among Resonant Catalyst, Unstable Catalyst, and Fertile Catalyst.
Planning Around Cauldron Outputs
The supplied Steam guide describes reaching Cauldrons as a midgame objective and calls the Cauldron “the key to everything.” While that guide focuses on broader progression rather than a complete recipe reference, its advice supports treating Cauldron production as a planned milestone.
A simple preparation checklist for the confirmed recipes is:
- Decide whether you need a specific gem or a Philosopher's Stone.
- For a Philosopher's Stone, prepare all three gem recipes rather than only one.
- Confirm that each recipe has its exact named catalyst or special input.
- Use the Cauldron Calculator when investigating combinations beyond the recipes documented here.
- Keep recipe changes in mind when experimenting with different inputs.
The available recipes also show why it is useful to separate your objectives. If you only need Ruby, its recipe is the shortest listed Cauldron jewelry process at 30.9 seconds. If your goal is a Philosopher's Stone, however, Ruby alone is only one-third of the required gem set.
| Goal | Cauldron Recipes Needed | Listed Cauldron Time |
|---|---|---|
| Ruby | Ruby | 30.9s |
| Sapphire | Sapphire | 38.2s |
| Emerald | Emerald | 45.5s |
| Philosopher's Stone | Ruby, Sapphire, Emerald, Philosopher's Stone | 174.6s |
This table covers processing time only. The sources do not provide acquisition methods or production chains for every Cauldron ingredient, so those details should not be assumed from this list.
If you are testing beyond the confirmed entries, record the exact three inputs and result as you work. The Steam discussion notes that there may be thousands of unique ingredient combinations, so a personal reference can help prevent repeated experiments. The Codex calculator is the supplied tool for checking those combinations.
