Identify clean water is an amateur-status sage ability in the study of Forester, allowing the character to determine whether naturally occurring water is safe for drinking. This is done through observation, odour, taste, and by considering the appearance of the surrounding landscape. By carefully noting these factors, the character can assess a given body of water’s purity without the use of tools or magic.

For convenience, the quality of water can be judged on a purity scale of 1 to 20, reflecting the likelihood of dangerous impurities. Most naturally occurring water will come from one of the following sources:

Purity Ratings
Purity Rating Water Taste Effects
20 pure, unusually fresh clean; no effect
19 pleasant 1 in 1000 chance of containing gastro-intestinal parasites
18 agreeable 1 in 100 chance of causing a gastro-intestinal disease
17 odd, earthy 1 in 10 chance of causing a gastro-intestinal disease
16 peculiar, metallic 1 in 6 chance of causing a gastro-intestinal disease
14-15 queer, stale 1 in 2 chance of any disease
13 bitter 2 in 3 chance of any disease
11-12 rank 3 in 4 chance of any disease
9-10 mouldy 3 in 4 chance of any disease, +1 severity
7-8 rancid, mouldy 5 in 6 chance of any disease, +2 severity
4-6 hint of decay, mouldy 7 in 8 chance of any disease, +3 severity
1-3 putrid, rotting 9 in 10 chance of being poisonous
Clear, flowing water, such as mountain streams and swift-moving rivers, will generally have a purity rating of 16 to 20. While this is the safest type of water, it may still be contaminated by mining runoff or animal defecation, particularly if the source is unknown.
Slow-moving water, such as lowland rivers and sluggish streams, will contain silt and range in purity from 5 to 17. These waters are more likely to carry detritus and disease, such as black water fever or cholera, which spread from decaying matter or tainted runoff from upstream.

Clear ponds, fed by underground springs, will typically have a purity rating between 12 and 20. Some algae may grow in such waters, though their purity depends largely on the surrounding terrain. A mountain tarn with a rocky or sandy bottom will be purer than a prairie or forest pond, where silt and organic material are more common.

Clear lakes, which are fed by rivers, will have a purity rating of 10 to 18. Like clear ponds, their safety depends on the landscape and vegetation. A high-altitude glacial lake will be fresher than a lowland basin, where runoff and organic debris may collect.

Stagnant ponds and lakes, including swamps, bogs, and freshwater marshes, will have suspended silt, decayed material, and abundant algae growth, with a purity rating of 1 to 11. These waters are the most dangerous, as they are prone to bacteria, parasites, and toxic plant life.

The sage ability allows the character to assess water quality in any wilderness environment, providing them with the knowledge necessary to seek the safest drinking sources while avoiding those that could lead to illness or worse.
