Every Source, Solvent and Purifier in the potion system. Search by name or effect, or narrow the list by tag, Rank and group.
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 |
Set by the Solvent. Vapor adds +1 Brew Rank; so does a compound of two Sources.

Compared against the Brew Rank, counting no higher than 3. A brew is matched when the Solvent and Purifier each share a tag with the Source; all three sharing one tag makes it Resonant (+Brew Rank to numeric totals).
| 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. |
| Source tag | Side effect |
|---|---|
| Vital | Poisoned for 10 minutes |
| Arcane | Sheds dim light (10 ft) and has disadvantage on Dexterity (Stealth) checks for 1 hour |
| Elemental | 1d6 per Brew Rank of the Source's damage type (fire if none) |
| Toxic | 1d6 poison damage per Brew Rank |
| Mental | Disadvantage on Wisdom saving throws for 1 hour |
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 |
|---|---|---|---|---|---|
| 1 | Common | 1 day | 1 hour at start, 1 hour at end | Anywhere | 1 |
| 2 | Uncommon | 4 days | 1 hour per day | Portable station, or a 4-day stop | 2 |
| 3 | Rare | 10 days | 4 hours per day | Stationary field lab | 3 |
| 4 | Very Rare | 30 days | 8 hours per day | Dedicated lab | 4 |
| 5 | Legendary | 90 days | Continuous, in shifts | Dedicated lab and crew | 5 |
Check DC = 10 + Brew Rank (counting no higher than 3), +5 per Brew Rank above 3, +5 if mismatched. Proficiency removes 1 check; expertise removes 2 and allows one reroll.
