Usually when you see a frog, toad, newt, or whatnot in fiction it's either of the "really generally poisonous" or the "gets you high" varieties. That's fairly realistic (because dosages are king in pharmacology), but I wanted more, so here's a suite of tables to generate medicinally useful amphibians of your very own! They're pretty self-explanatory, though you may need to look up some terms if you're not familiar with biology, ecology, and pharmacology. (Go wiki-walking! Learn! It's good for you!)

While you're researching, here are some topics of interest when it comes to real-world amphibians (that can also be adapted for use in games):
- Aposematism: Honest warning coloration on animals. It's often bright colors, but applies to any distinctive coloration or pattern that makes the creature conspicuous and says "go away" when you really should leave it alone.
- Ecological indicators: Indicator species are plants and animals that are highly sensitive to changes in their habitat. When they're thriving, it's a good sign for the whole area. When they're declining, it's a sign that something's wrong and you need to sit up and take notice. Amphibians are often important indicator species because their highly permeable skin and water-reliant lifecycle makes them very vulnerable to pollution and disruption in their habitats.
- The real-life toxins produced by amphibians in nature. They tend to fall into a similar band of nerve-disrupting chemicals and are absolutely fascinating.
- Poison dart frogs (Phyllobates): Batrachotoxin, among other chemicals
- European fire salamanders: Samandarin
- North American newts in the family Taricha: Tetrodotoxin (The same chemical that makes fugu potentially lethal, yes)
- Toads (a bunch, but not all species): Bufotoxins
What's cool about these is that usually the amphibian doesn't produce the toxin itself. It gets it from its diet of other poisonous things (usually insects), either by sequestering the chemicals in their tissues or transforming them from a precursor chemical found in their prey to something even more toxic. If these amphibians are caught and kept, they'll gradually lose their toxicity because their diet in captivity doesn't contain the right chemicals. If they're raised in captivity and never eat a wild diet, they're not poisonous at all!
This is why you have to adventure/quest for your medicinally valuable amphibians, they can't be farmed and still retain their potency. (Unless you create a free-range amphibian ranch, which sounds adorable.)
Once you've finished reading about the delightful, mildly morbid world of poisonous amphibian toxicology, roll some dice!
For some of the tables I've only given guidelines, it's up to you to fill in the details and make it work. Like the coloration table. If you roll "brilliant" it could be brilliant blue, red, orange, whatever so long as it's retina-searing and screams "do not eat!" Follow your heart and make something cool.
(Remember! If you'd like to own these tables in a PDF or print format, along with all the excellent work from other contributors, go grab yourself a copy of Penicillin Vol.3.)
