One job per component
The Source decides what the potion does. Solvents and Purifiers only change parameters of that effect: strength, duration, onset, form, area, targeting, shelf life and noticeability. They never add a new effect.
| Component | Its job | Its Rank decides |
|---|---|---|
| Source | What the potion does | The base Brew Rank |
| Solvent | How the effect arrives: form plus one parameter | Whether the potion is Diluted |
| Purifier | How well the potion holds together | Whether the potion is Corrupt or Extended |
Forms
Set by the Solvent. Vapor adds +1 Brew Rank; so does a compound of two Sources.

Weakest link
Compared against the Brew Rank, counting no higher than 3. A brew is matched when the Solvent and the Purifier each share at least one tag with the Source. When every component has exactly the same tags and no others, the brew is Resonant: add the Brew Rank to numeric totals and +2 to brewing checks. Solvents that count as every tag never make a brew Resonant.
| Configuration | State | Result |
|---|---|---|
| Solvent < Brew Rank | Diluted | Numeric effects lose half their dice (minimum 1). Durations halved. On/off effects suppress the condition for 1 hour instead. |
| Purifier < Brew Rank | Corrupt | Full effect plus a side effect by the Source's tag. |
| Purifier = Brew Rank | Stable | Standard effect and duration. |
| Purifier > Brew Rank | Extended | Durations x2. Instant effects use maximized dice. |

Brewing time
Tending is hands-on work; simmering runs on its own. A missed tending session forces an automatic check. Mismatched tags double both kinds of time and add a check.
| Brew Rank | Rarity | Total | Tending | Where | Checks |
|---|
Checks
DC = 10 + 2 × Brew Rank, +5 if mismatched. Number of checks = Brew Rank, +1 if mismatched. Each check is judged by its margin.
Checks are spread evenly through the brew, and the last one comes when it finishes. A Rank 3 brew (10 days, 3 checks) is checked after day 3, after day 7, and at the end. A Rank 1 brew that's mismatched (2 days, 2 checks) is checked after 24 hours and at the end. You must be at the brew when a check comes due. If you aren't, it counts as a missed tending session, which forces an extra check. A forced check is rolled when the session is missed.
| Result | What happens |
|---|---|
| Miss by 5 or more | Complication: roll on the table for the Brew Rank. |
| Miss by 1 to 4 | Setback: repeat one tending session. The ingredients are safe. |
| Meet or beat by 1 to 4 | Success. |
| Beat by 5 or more | Mastery mark. A mark on every check makes the potion Masterwork: choose Potent, Lasting, Generous or Subtle. |
Skill secures checks before rolling (proficiency 1, expertise 2): a secured check is a success but can't earn a mark, so securing rules out Masterwork. Expertise also rerolls one check per brew.
| Preparation | Effect | Cost |
|---|---|---|
| Resonant brew (identical tags) | +2 | None |
| Careful brewing | +2 | Double the tending time |
| Well-equipped lab | +2 | The brew can't travel |
| An assistant's Help | Advantage on one check | The assistant must be proficient |
| On the road | −2 | None |
| Rushed | −5 | Halve the tending and simmering time |
Wild Mutations
Permanent effects. A Rank 3+ complication of Permanent Alteration rolls here, as do Cauldron Milk and the Robes of the Wildeganger.
